             IIJ Announces Second Quarter Results for the
                  Fiscal Year Ending March 31, 2008


    TOKYO--(BUSINESS WIRE)--Nov. 13, 2007--Internet Initiative Japan
Inc. (Nasdaq:IIJI) (Tokyo Stock Exchange First Section: 3774) ("IIJ"),
one of Japan's leading Internet-access and comprehensive network
solutions providers, today announced its financial results for the
second quarter of the fiscal year ending March 31, 2008 ("FY2007")(1).

              Highlights of Second Quarter FY2007 Results

    --  Revenue totaled JPY 16,294 million ($ 141.7 million), an
        increase of 16.3% from 2Q06.

    --  Operating income was JPY 1,125 million ($9.8 million), an
        increase of 38.6% from 2Q06.

    --  Net income was JPY 2,907 million ($25.3 million), an increase
        of 37.1% from 2Q06.

        dividend of JPY 750 per share of common stock for the interim
        period ended September 30, 2007 (400 American Depository

                    Financial Targets for FY2007(2)

    --  We are maintaining our initial targets for the full FY2007
        that we disclosed on May 15, 2007.

    --  We plan to pay an additional cash dividend of JPY 750 per
        share of common stock for FY2007.

    Overview of 2nd Quarter FY2007 Financial Results and Business
Outlook(2)

    "We continued to record good results in 2Q07," said Koichi Suzuki,
President and CEO of IIJ. "The revenues and operating income have
shown a steady increasing trend supported by the favorable increase in
monthly recurring revenues from our Internet connectivity and
value-added services, or VAS. Revenues from Internet connectivity
services increased continuously in 2Q07 mainly due to the shift by
corporate customers to higher speeds and our business expansion in the
home users market by our acquisition of hi-ho, Inc., or hi-ho.
Corporate customers keep showing strong demands for our outsourcing
services including anti-spam services and data centers to reduce the
risk of interruptions to their businesses and increase security
measures. As a result, the gross margin from connectivity and VAS
increased by 48.4% compared to 2Q06. For systems integration, or SI,
we continued to see strong demands and revenues from SI increased by
10.3% compared to 2Q06. Some projects are becoming larger in scale and
are expected to be completed in the last half of FY2007 and the order
backlog for SI and equipment sales increased by 82.8% compared to
2Q06."

    "In 2Q07, we continued to build the basis for further growth in
the middle and long-term," continued Suzuki. "In August 2007, we
announced that we would provide our high-quality content distribution
platform to "acTVila", TV portals established by major home appliance
manufacturers in Japan for digital televisions connected to the
Internet. In September 2007, GDX Japan Inc., or GDX, our consolidated
subsidiary, announced that it will provide "GDX Trusted Platform" to
offer corporate customers a revolutionary and highly reliable e-mail
messaging infrastructure."

------------------------------------------- -------- --------- -------

    Connectivity and VAS revenues were JPY 7,936 million in 2Q07, an
increase of 28.9% compared to 2Q06. The increase was mainly due to an
increase in revenues from connectivity services for corporate users,
JPY 1,080 million of revenues from connectivity services for home
users provided by hi-ho, which we acquired on June 1, 2007, and an
increase in revenues from value-added services overall.

    SI revenues increased 10.3% to JPY 7,968 million in 2Q07 compared
to 2Q06. The increase was due to an increase in one-time revenues from
systems construction as well as monthly recurring revenues from
systems operation and maintenance.

    Equipment sales revenues were JPY 391 million in 2Q07, a decrease
of 37.9% compared to 2Q06.

    Cost of revenues was JPY 12,869 million in 2Q07, an increase of
12.4% compared to 2Q06.

------------------------------------------- -------- --------- -------

    Cost of Connectivity and VAS revenues was JPY 6,598 million in
2Q07, an increase of 25.6% compared to 2Q06, mainly due to JPY 1,081
million of costs along with revenues of JPY 1,314 million from hi-ho,
which we acquired on June 1, 2007, and an increase in personnel
related costs and supplies costs. The cost of revenues also included
amortization of intangible assets of JPY 21 million for hi-ho.

    Cost of SI revenues was JPY 5,938 million in 2Q07, an increase of
5.8% compared to 2Q06. The increase was mainly due to an increase in
revenues from SI projects and an increase in personnel expenses.

    Cost of Equipment Sales revenues was JPY 333 million in 2Q07, a
decrease of 42.9% compared to 2Q06.

    Sales and marketing expenses were JPY 1,088 million in 2Q07, an
increase of 29.1% compared to 2Q06. The increase was mainly due to an
increase in personnel related expenses with business expansion and
sales and marketing expenses related to hi-ho of JPY 155 million.

    General and administrative expenses were JPY 1,153 million in
2Q07, an increase of 33.7% compared to 2Q06. The increase was mainly
due to an increase in personnel related expenses and an increase in
rent expenses caused by expansion of offices along with the business
growth.

    Research and development expenses were JPY 60 million in 2Q07, an
increase of 42.1% compared to 2Q06.

    Operating income

    Operating income was JPY 1,125 million in 2Q07, an increase of
38.6% compared to 2Q06. The increase was mainly due to an increase in
gross margin from connectivity and VAS of JPY 436 million and gross
margin from SI of JPY 419 million, despite of the increase in sales
and marketing expenses and general and administrative expenses.

    Other income (expense) and others

    Other expense in 2Q07 was JPY 184 million, compared to other
income of JPY 334 million in 2Q06. The decrease was mainly due to a
decrease in gains from the sale of available-for-sale securities.

    Income tax benefit in 2Q07 was JPY 1,980 million, compared to
income tax benefit of JPY 1,109 million in 2Q06. The increase is
mainly due to deferred tax benefits of JPY 2,114 million resulting
from a reduction of the valuation allowance against deferred income
tax assets due to the increasing income trend and the application of
the consolidated tax filing system for IIJ and its wholly owned
subsidiaries.

    Minority interests in losses of subsidiaries in 2Q07 was JPY 15
million, an amount which was affected by the elimination of minority
interests related to our 4 consolidated subsidiaries wholly owned by
us, after we made our two subsidiaries, IIJ Technology Inc. and Net
Care, Inc. wholly owned through the share exchanges in May 2007.
Minority interests in losses of subsidiaries were related to GDX.

    Equity in net loss of equity method investees in 2Q07 was JPY 29
million, which was mainly due to equity in net loss of Internet
Revolution Inc.

    Net income was JPY 2,907 million in 2Q07, an increase of 37.1%
compared to 2Q06.

    Financial Condition

    Balance Sheets

    As of September 30, 2007, total assets increased by JPY 5,545
million from the amount as of March 31, 2007 to JPY 53,238 million.
For current assets, inventories increased by JPY 767 million, related
to on-going SI projects; prepaid expenses increased by JPY 682
million, mainly for maintenance expenses related to SI projects; other
current assets increased by JPY 847 million mainly due to an increase
in current deferred tax assets (net) resulting from a reduction of the
valuation allowance; and cash decreased by JPY 1,885 million, each
from the respective amount as of March 31, 2007. Property and
equipment increased by JPY 1,468 million from the amount as of March
31, 2007 mainly due to our acquisition of hi-ho and an increase in
property for us and to provide services to our customers. Intangible
assets increased by JPY 2,940 million from the amount as of March 31,
2007, mainly due to the recording of intangible assets of JPY 2,302
million upon our acquisition of the minority shares of two
consolidated subsidiaries and of JPY 659 million upon our acquisition
of hi-ho, including amortizable intangible assets of JPY 289 million.
Other assets increased by JPY 1,217 million mainly due to an increase
in non-current deferred tax assets (net) resulting from a revision of
valuation allowance. The fair value of available-for-sale securities
as of September 30, 2007 decreased by JPY 266 million from the amount
of March 31, 2007 to JPY 1,043 million.

    For current liabilities, short-term borrowings increased by JPY
4,600 million from the amount as of March 31, 2007, mainly related to
our acquisition of shares of two consolidated subsidiaries from their
respective minority shareholders, and accounts payable decreased by
JPY 2,338 million from the amount as of March 31, 2007.

    Total shareholders' equity as of September 30, 2007 was JPY 23,786
million, an increase of JPY 3,674 million from the amount as of March
31, 2007.

    Cash Flows

    Cash as of September 30, 2007 was JPY 11,670 million, a decrease
of JPY 1,190 million compared to 2Q06.

    Net cash provided by operating activities in 2Q07 was JPY 1,444
million, compared to JPY 1,608 million in 2Q06. In 1Q07, we recorded
net cash used in operating activities of JPY 1,328 million mainly due
to changes in operating assets and liabilities resulting from an
increase in inventories and prepaid expenses related to on-going SI
projects, a decrease in accounts payable and payment of income tax.
However in 2Q07, we recorded net cash provided by operating activities
because operating income continued to increase, mainly due to a steady
increase in revenues from connectivity and VAS, and there was less
effect from changes in operating assets and liabilities during this
quarter.

    Net cash used in investing activities in 2Q07 was JPY 832 million,
compared to JPY 855 million in 2Q06. We paid JPY 422 million for the
purchase of property and equipment and JPY 250 million for an
investment in an equity method investee.

    Net cash used in financing activities in 2Q07 was JPY 1,552
million, compared to JPY 983 million in 2Q06. We recorded a net
increase in short-term borrowings with initial maturities less than
three months of JPY 1,000 million. We also recorded repayments of
short-term borrowings with initial maturities over three months and
long-term borrowings of JPY 1,769 million and principal payments under
capital leases of JPY 883 million.

    2nd Quarter FY2007 Business Review

    Analysis by Service

    Connectivity and VAS

    For connectivity services for corporate use, customers continued
to shift to higher speeds. Total contracted bandwidth increased by
81.7 Gbps to 334.9 Gbps compared to 2Q06.

    Revenues from connectivity services for corporate users were JPY
3,009 million, an increase of 7.5% compared to 2Q06. Revenues from IP
Services, the services mainly used by corporate headquarters and data
centers, increased by 6.2% compared to 2Q06, primarily due to new
contracts and the shift by our corporate customers to higher speeds.
Revenues from broadband services increased by 22.8% compared to 2Q06,
largely due to the expansion of broadband utilization in the corporate
internal network.

    Revenues from connectivity services for home users were JPY 1,489
million in 2Q07, an increase of 201.9% compared to 2Q06. The increase
was mainly due to additional revenues of JPY 1,080 million from hi-ho,
which we acquired on June 1, 2007, partially offset by the decrease in
revenues from services under IIJ Brand and OEM services.

    VAS revenues were JPY 2,379 million in 2Q07, an increase of 24.8%
compared to 2Q06. The increase was mainly due to an increase in
revenues from e-mail, security-related services and data centers,
resulting from an increase in demand for outsourcing services by
corporate customers.

    Other revenues were JPY 1,059 million in 2Q07, an increase of
10.7% compared to 2Q06.

    As a result, revenues from Internet connectivity and VAS in 2Q07
were JPY 7,936 million, an increase of 28.9% compared to 2Q06. The
gross margin for Internet connectivity and VAS in 2Q07 was JPY 1,337
million, an increase of 48.4% compared to 2Q06. The gross margin ratio
in 2Q07 improved to 16.9% compared to 14.6% in 2Q06.

    SI

    Revenues from SI were JPY 7,968 million in 2Q07, an increase of
10.3% compared to 2Q06. The increase was mainly due to an increase of
13.4% in monthly recurring revenues from systems operation and
maintenance compared to 2Q06 and an increase of 7.7% in one-time
revenues from systems construction compared to 2Q06. The order backlog
for SI and equipment sales at September 30, 2007 was JPY 18,938
million, an increase of 82.8% from the amount as of September 30,
2006. The increase is mainly because some projects are becoming larger
in scale and are expected to be completed in the last half of FY2007.

    The gross margin for SI in 2Q07 was JPY 2,030 million and the
gross margin ratio in 2Q07 was 25.5%, compared to 22.3% in 2Q06.

    About Internet Initiative Japan Inc.

    Founded in 1992, Internet Initiative Japan Inc. (IIJ, NASDAQ:
IIJI, Tokyo Stock Exchange First Section: 3774) is one of Japan's
leading Internet-access and comprehensive network solutions providers.
The company has built one of the largest Internet backbone networks in
Japan, and between Japan and the United States. IIJ and its group of
companies provide total network solutions that mainly cater to
high-end corporate customers. The company's services include
high-quality systems integration and security services, Internet
access, hosting/housing, and content design.

    Statements made in this press release regarding IIJ's or its
management's intentions, beliefs, expectations, or predictions for the
future are forward-looking statements that are based on IIJ's and its
management's current expectations, assumptions, estimates and
projections about its business and the industry. These forward-looking
statements, such as statements regarding FY2007 revenues and operating
and net profitability, are subject to various risks, uncertainties and
other factors that could cause IIJ's actual results to differ
materially from those contained in any forward-looking statement.
These risks, uncertainties and other factors include: IIJ's ability to
maintain and increase revenues from higher-margin services such as
systems integration and value-added services; the possibility that
revenues from connectivity services may decline substantially as a
result of competition and other factors; the ability to compete in a
rapidly evolving and competitive marketplace; the impact on IIJ's
profits of fluctuations in costs such as backbone costs and
subcontractor costs; the impact on IIJ's profits of fluctuations in
the price of available-for-sale securities; the impact of
technological changes in its industry; IIJ's ability to raise
additional capital to cover its indebtedness; the possibility that
NTT, IIJ's largest shareholder, may decide to exercise substantial
influence over IIJ; and other risks referred to from time to time in
IIJ's filings on Form 20-F of its annual report and other filings with
the United States Securities and Exchange Commission.

1. Results of Operations

(1) Analysis of Consolidated Results of Operations

a. Overview of Consolidated Results for the Interim Period Ended September 30,
2007

   The Japanese economy for the interim period ended September 30, 2007 seems to
continue to be in a gentle recovery trend mainly resulting from an improving
trend of employment and recovering personal consumptions, as well as
improvements in corporate earnings and an increase of corporate capital
investments, while a trend of the economy in the United States and fluctuation
in crude oil prices must be watched carefully.

   For the data communication market which the IIJ Group belongs to, the IIJ
Group continues to see steadily increasing corporate IT investment and
expenditure and corporate customers are shifting to higher speeds for Internet
connectivity and showing the strong demands for outsourcing services to reduce
the risk of interruptions to their businesses and increase security measures.

   Under such business environment, for the business results of the IIJ Group in
the interim period ended September 30, 2007, revenues from connectivity services
and value-added services ("VAS") such as anti-spam services and data centers
increased steadily. Gross margin from connectivity and VAS increased by JPY 844
million, 49.8% year-over-year and the structural income increasing trend
continued from the previous quarter. Revenues from systems integration ("SI")
increased by JPY 1,049 million, 7.9% year-over-year. Some projects are becoming
larger in scale and the order backlog for SI and equipment sales increased by
JPY 8,576 million, 82.8% year-over-year.

   As for business development, the IIJ Group continued to build the structure
for its further growth in the middle and long-term. The IIJ Group engaged in the
video distribution business such as provision of content distribution platform
to "acTVila", TV portals for digital televisions. IIJ established GDX Japan Inc.
to prepare to introduce message exchange network services. IIJ also acquired
hi-ho, Inc. ("hi-ho"), an Internet Service Provider for home users.

   As a result, for the consolidated results of operations for the interim
period ended September 30, 2007, revenues were JPY 29,990 million, an increase
of 13.4% year-over-year. Gross margin was JPY 6,179 million, an increase of
27.1% year-over-year. Operating income was JPY 1,816 million, an increase of
32.5% year-over-year. Income before income tax benefit was JPY 1,697 million, a
decrease of 20.8% year-over-year, mainly due to a decrease in the gains from the
sale of available-for-sale securities. Net income was JPY 3,477 million, an
increase of 21.8% year-over-year, mainly due to the record of deferred tax
benefits of JPY 1,970 million.

      ----------------------------------------------------------------------------------------------------------------------


   Revenues from  connectivity  and VAS were JPY 14,807 million,  an increase of
23.2%  year-over-year,  mainly due to an increase in revenues from  connectivity
services for  corporate  users,  JPY 1,419 million (for four months) of revenues
from connectivity  services for home users provided by hi-ho, which IIJ acquired
on June 1, 2007, and an increase in revenues from VAS overall.

   SI  revenues   increased  to  JPY  14,302   million,   an  increase  of  7.9%
year-over-year,  due to an increase in one-revenues from systems construction as
well as monthly recurring revenues from systems operation and maintenance, along
with increasing corporate IT investment and expenditure.

   Equipment  sales  revenues  were  JPY  881  million,   a  decrease  of  24.8%
year-over-year.

      ----------------------------------------------------------------------------------------------------------------------


   The cost of connectivity  and VAS revenues,  which are mostly fixed-type cost
such as  cost  for  backbone,   was  JPY  12,268  million,  an increase of 18.8%
year-over-year.  The increase is mainly due to JPY 1,488  million of costs along
with  revenues of JPY 1,748  million  from hi-ho,  which IIJ acquired on June 1,
2007 (both for four  months),  and an increase in  personnel  related  costs and
supplies  costs.  The cost of revenues also included  amortization of intangible
assets of JPY 21 million for hi-ho.

   The cost of SI revenues,  which are mostly variable-type cost such as
outsourcing costs and purchase, was JPY 10,787 million, an increase of 5.8%
year-over-year. The increase  was mainly due to an increase in revenues from SI
projects and an increase in personnel expenses.

   The cost of equipment sales revenues was JPY 756 million, a decrease of 29.0%
year-over-year, as revenues from equipment sales declined.

3) Sales and Marketing Expenses, General and Administrative Expenses and
   Research and Development

   Sales and marketing  expenses were JPY 2,027 million,  an increase of 24.2%
year-over-year.  The  increase  mainly due to an increase in  personnel  related
expenses and advertising  expenses,  and sales and marketing expenses related to
hi-ho of JPY 184 million (for four months).

   General and  administrative  expenses were JPY 2,220 million,  an increase of
24.9%  year-over-year.  The  increase was mainly due to an increase in personnel
related expenses and an increase in rent expenses caused by expansion of offices
along with the business growth.

   Research and development  expenses were JPY 116 million, an increase of 41.7%
year-over-year.

5) Operating Income

   Operating   income   was  JPY  1,816   million,   an   increase   of  32.5%
year-over-year.  The  increase  was due to an  increase  in  gross  margin  from
connectivity  and VAS of JPY 844  million  and gross  margin  from SI of JPY 454
million, despite of the increase in sales and marketing expenses and general and
administrative expenses.

6) Other Income (Expense)

   Other  expense  was JPY 119  million,  compared  to other  income  of JPY 774
million in the interim period ended  September 30, 2006. The decrease was mainly
due to a decrease in gains from the sale of available-for-sale securities to JPY
214 million from JPY 925 million in the interim period ended September 30.

7) Income before Income Tax Benefit

   Income before income tax benefit was JPY 1,697  million,  a decrease of 20.8%
year-over-year.  The decrease was because IIJ recorded  other expense of JPY 119
million mainly due to the decrease in gains from the sale of  available-for-sale
securities.

8) Income Tax Benefit, Minority Interests and Equity in Net Loss of Equity
Method Investees

   Income tax benefit was JPY 1,805  million,  compared to income tax benefit of
JPY 960 million in the interim period ended September 30, 2006. The increase was
mainly due to  deferred  tax  benefits  of JPY 1,970  million  resulting  from a
reduction of the valuation  allowance  against deferred income tax assets due to
the increasing  income trend and the application of the  consolidated tax filing
system for IIJ and its wholly owned subsidiaries.

   Minority interests in losses of subsidiaries were JPY 24 million, affected by
the elimination of minority interests related to our 4 consolidated subsidiaries
wholly owned by us, after IIJ made our two  subsidiaries,  IIJ  Technology  Inc.
("IIJ-Tech")  and Net Care Inc.  ("Net  Care")  wholly  owned  through the share
exchanges in May 2007. Minority interests in losses of subsidiaries were related
to GDX.

   Equity in net loss of equity method  investees was JPY 49 million,  which was
mainly due to equity in net loss of Internet Revolution Inc.

9) Net Income

   Net income was JPY 3,477 million, an increase of 21.8% year-over-year.



c. Analysis by Service

1) Internet Connectivity and VAS

   Revenues from connectivity services for corporate use were JPY 5,981 million,
an increase of 8.1%  year-over-year.  IIJ had new  contracts  for IP Service and
customers shifted to higher speeds.

   Revenues from connectivity  services for home use were JPY 2,295 million,  an
increase of 133.4%  year-over-year.  The increase  was mainly due to  additional
revenues of JPY 1,419 million from hi-ho (for four months),  partially offset by
the decrease in revenues from services under IIJ Brand and OEM services.

   Revenues   from  VAS  were  JPY  4,485   million,   an   increase   of  23.0%
year-over-year.  The  increase  was mainly due to a steady  increase in revenues
from network-related outsourcing services such as e-mail, securities-related and
Internet  VPN  services  and data  centers  affected by an increase in corporate
outsourcing needs.

   Other revenues were JPY 2,046 million, an increase of 10.2% year-over-year.

   As a result,  revenues from connectivity  services and VAS totaled JPY 14,807
million,  an increase of 23.2%  year-over-year.  The gross  margin was JPY 2,539
million,  an increase of 49.8%  year-over-year and the gross margin ratio was up
to 17.1% from 14.1% of the interim period ended September 30, 2006.

2) SI

   Revenues from SI were JPY 14,302 million, an increase of 7.9% year-over-year.
One-time revenues from systems  construction were JPY 6,721 million, an increase
of  1.1%   year-over-year.   Recurring   revenues  from  systems  operation  and
maintenance  steadily  increased  to JPY 7,581  million,  an  increase  of 14.8%
year-over-year.  The order backlog for SI and  equipment  sales at September 30,
2007 was JPY  18,938  million,  an  increase  of 82.8%  from  the  amount  as of
September 30, 2006.  The increase was mainly because some projects were becoming
larger in scale and were expected to be completed in the last half of FY2007.

   The  gross  margin  from SI was JPY  3,515  million,  an  increase  of  14.8%
year-over-year, and the gross margin ratio was 24.6%.

d. Target for the fiscal year ending March 31, 2008

   The Japanese economy is expected to continue to be in a gentle recovery
trend, while a trend of the economy in the United States and fluctuation in
crude oil prices must be watched carefully.

   The business results of the IIJ Group in the interim period ended September
30, 2007 were almost in line with the target for the interim period ended
September 30, 2007 that IIJ disclosed in the press release made on August 13,
2007 (see note).

   IIJ does not revise the target for the fiscal year ending March 31, 2008,
that IIJ disclosed in the press release on August 13, 2007. The targets are JPY
69,000 million for total revenues, an increase of 20.9% year-over-year, JPY
4,600 million for operating income, an increase of 31.4% year-over-year, JPY
5,100 million for income before income tax benefit, an increase of 1.0%
year-over-year, and JPY 5,600 million for net income, an increase of 3.5%
year-over-year.

   (Note) On August 13, 2007, IIJ only revised its target for net income for the
interim period ended September 30, 2007, because IIJ planed to revise valuation
allowance against deferred income tax assets, related to the increasing income
trend and the application of the consolidated tax payment system for IIJ and its
wholly owned subsidiaries. The revision was related to the timing of the
recording of income tax benefits or expenses within the fiscal year and IIJ did
not revise targets for the financial results for full FY2007.

 (2) Analysis for Financial Condition

a. Assets, Liabilities and Total Shareholders' Equity



   As of September 30, 2007, total assets increased by JPY 5,545 million from
the amount as of March 31, 2007 to JPY 53,238 million. For current assets,

3. Management Policies

(1) Basic Management Policies

   IIJ aims to contribute in creating a new market and in innovating industries
by leading the information society of Japan with Internet technology. By
practicing its management philosophy, it also continuously seeks to maximize its
corporate value and to fulfill its social responsibility.

(2) Target Management Indicators

   In conducting its business activities, the IIJ Group closely considers the
composition of total revenues, profitability, financial position, and other
factors. The IIJ Group is making efforts to enhance its profitability by
increasing revenues and controlling costs, sales and marketing expenses and
general and administrative expenses, while closely watching its revenue growth
ratio, gross margin ratio, operating margin ratio and other figures.

(3) Medium and Long-term Business Strategies

   The IIJ Group recognizes that customer needs and demands for the use of
network system will become more advanced and diverse as Internet use in business
and public organizations is increasing due to the expand in broadband network.
The IIJ Group continues to recognize the current market environment to be an
opportunity for its growth, because it expects that corporate customers and
public organizations, its main customers, will increase their needs for reliable
network systems and outsourcing services for their network systems, such as
security measures. On the contrary, the IIJ Group sees that the competition with
competitors for Internet connectivity, VAS and SI will further deepen. While
price competitions for Internet connectivity services are still severe, the IIJ
Group believes that it can be competitive by providing solutions together with
VAS and SI. The IIJ Group believes that it is important for the Group to promote
its research and development for Internet and to continuously provide its
customers with reliable and value-added solutions for the enhancement of the IIJ
Group business.

(4) Issues that Should be Addressed

   Although the environment surrounding the IIJ Group is very favorable, it is
important for the IIJ Group to continue to provide reliable and competitive
services at the right timing to capture the needs for network systems of
enterprises and public organizations. For its medium and long term business
expansion, it is also important for the IIJ Group to expand its business field
by M&A and creation of new business and to promote its partnerships with
business partners properly. In the interim period ended September 30, 2007, IIJ
made hi-ho fully owned by acquiring all the shares of hi-ho and established GDX
and TN and invested in TCC. In addition, IIJ believes that it is important for
IIJ to perform its potential more comprehensively as a Group and construct its
Group business structure to promote an effective business. In May 2007, IIJ made
its two subsidiaries, IIJ-Tech and Net Care wholly owned through the share
exchanges. In September 2007, IIJ applied for a consolidated tax payment system
to introduce the system in the fiscal year ended March 31, 2009.

   It is important for the IIJ Group to attract and educate excellent personnel
to maintain its growth in the future. The IIJ Group is actively recruiting
mid-carriers including managements and recent graduates on a regular basis. The
number of the employees on the consolidated basis at the end of the interim
period ended September 30, 2007 was 1,327 (including 83 recent graduates joined
the IIJ Group in April 2007), an increase of 172 compared to the end of the
fiscal year ended March 31, 2007.

(5) Other Issues to be Addressed

   For the interim period ended September 30, 2007, IIJ provides Internet
connectivity services for the amount of JPY 351 thousand, to Applied Research
Institute, Inc. which Koichi Suzuki, President and CEO of IIJ has 100% voting
right. It is conducted under normal business relationship.

Principal Standard Items for Preparation of Consolidated  Financial Statements
------------------------------------------------------------------------------
for the Interim Period Ended September 30, 2007
-----------------------------------------------
The Terminology, Form, and Preparation Methods for the Consolidated Financial
Statements for the Interim Period Ended September 30, 2007

  The consolidated financial statements for the interim period ended September
30, 2007 have been prepared under the accounting principles, procedures and ways
of presentations requested for the issuance of American Depository Receipts
("ADRs") and others (generally accepted accounting principles in the United
States of America ("U.S. GAAP"), including Accounting Research Bulletins
("ARB"), Accounting Principles Board ("APB") Opinions, Statement of Financial
Accounting Standards ("SFAS") and related interpretation guidelines) in
accordance with the provisions of article 87 "provisions for the terminology,
form, and preparation methods for interim consolidated financial statements"
(Ministry of Finance, ordinance No. 24, 1999).

  IIJ registered the issuance of ADRs under the United States Securities and
Exchange Commission ("the United States SEC") and listed the ADRs on NASDAQ
market in August 1999. Accordingly, IIJ regularly files its annual report on
Form 20-F in English with the United States SEC, including consolidated
financial statements in English prepared under U.S. GAAP, in accordance with
Rule 13 of the U.S. Securities Exchange Act of 1934, as amended.

  Summary of Significant Accounting Policies.

Basis of Presentation

  IIJ maintains its record in accordance with generally accepted accounting
principles in Japan. Certain adjustment and reclassifications have been
incorporated in the accompanying consolidated financial statements to conform to
U.S. GAAP. These adjustments were not recorded in the statutory accounts.

   In this document,  a part of the financial  statements for the interim period
ended September 30, 2006 is  reclassified in accordance with the  representation
of the financial statements for the interim period ended September 30, 2007.

Consolidation

   The consolidated financial statements for the interim period ended September
30, 2007 include the accounts of IIJ and all of its subsidiaries, Net Care,
IIJ-Tech, IIJ-FS, NCJ, which was established in August 2006, GDX, in which IIJ
invested in April 2007, hi-ho, which became IIJ's consolidated subsidiary in
June 2007 and IIJ America, which all, except for IIJ America, have interim
periods ending September 30. IIJ America's interim period end is June 30 and
such date was used for purposes of preparing the consolidated financial
statements for the interim period ended September 30, 2007 as it is not
practicable for the subsidiary to report its financial results as of September
30. There were no significant events that occurred during the intervening period
that would require adjustment to or disclosure in the accompanying consolidated
financial statements. Intercompany transactions and balances have been
eliminated in consolidation. Investments in companies over which IIJ has
significant influence but not control are accounted for by the equity method.
For other than a temporary decline in the value of investments in equity method
investees below the carrying amount, the investment is reduced to fair value and
an impairment loss is recognized.

   A subsidiary or equity method investee may issue its shares to third parties
at amounts per share in excess of or less than the Company's average per share
carrying value. With respect to such transactions, the resulting gains or losses
arising from the change in ownership are recorded in income for the year in
which such shares are issued.

Use of Estimates

   The preparation of financial statements in conformity with U.S. GAAP requires
management to make estimates and assumptions that affect the reported amounts of
assets and liabilities and disclosure of contingent assets and liabilities at
the date of the financial statements and reported amounts of revenues and
expenses during the reporting period. Significant estimates and assumptions used
are primarily in the areas of evaluation of cost method investments, valuation
allowances for deferred tax assets, allowance for doubtful accounts,
determination of pension benefit costs and obligations, estimated useful lives
of fixed assets and impairment of long-lives assets. Actual results could differ
from those estimates.

Revenue Recognition

   Revenues from customer connectivity services consist of Internet connectivity
services for corporate users and Internet connectivity services for home users.
Internet connectivity services for corporate users represent IP services and
broadband services such as IIJ FiberAccess/F Service. Internet connectivity
services for home users are provided under IIJ brand such as IIJ4U and IIJmio,
hi-ho brand and others, and include dial-up services, optical fiber or ADSL
based broadband services. The term of these contracts is one year for Internet
connectivity services for corporate users and generally one month for Internet
connectivity services for home use. All these services are billed and recognized
monthly on a straight-line basis.



   VAS revenues consist principally of sales of various Internet access-related
services such as firewall services. VAS also include monthly fees from data
center services such as housing, monitoring, and security services. Other
revenues under connectivity and VAS consist principally of Wide-area Ethernet
services and call-center customer support. The terms of these services are
generally for one year and revenues are recognized on a straight-line basis
during the service period.

   Initial set up fees received in connection with connectivity services and VAS
are deferred and recognized over the contract period.

   SI revenues consist principally of the development of Internet network
systems and related maintenance, monitoring and other operating services. The
development of the Internet network systems includes planning, systems design,
and construction services, and equipment and software purchased from third
parties. SI service is subject to the Emerging Issues Task Force ("EITF") Issue
No. 00-21, "Revenue Arrangements with Multiple Deliverables". For deliverables
in multiple-element arrangements, the guidance below is applied for separability
and allocation. A multi-element arrangement is separated into more than one unit
of accounting if all of the following criteria are met:

-  The delivered item(s) has value to the client on a stand-alone basis;

-  There is objective and reliable evidence of the fair value of the undelivered
   item(s); and

-  If the  arrangement  includes  a  general  right of  return  relative  to the
   delivered  item(s),  delivery or  performance of the  undelivered  item(s) is
   considered probable and substantially in the control of the company.

   If these  criteria are not met, the  arrangement is accounted for as one unit
of accounting  which would result in revenue being recognized on a straight-line
basis or being  deferred until the earlier of when such criteria are met or when
the last  undelivered  element is delivered.  If these criteria are met for each
element and there is objective and reliable evidence of fair value for all units
of accounting in an arrangement,  the arrangement  consideration is allocated to
the separate units of accounting based on each unit's relative fair value.

   The period for the development of the systems is less than one year and
revenues are recognized when network systems and equipment are delivered and
accepted by the customer. When the equipment or system is delivered prior to
other elements of the arrangement, revenue is deferred until other service
elements are completed and accepted by the customer because the customer may
return all of the equipment or system in the event that the Company does not
complete other service elements. Maintenance, monitoring and operating service
revenues are recognized ratably over the separate contract period, which is
generally for one year.

   Equipment sales are reported on a gross or net basis in accordance with EITF
Issue No. 99-19 "Reporting Revenue Gross as a Principal versus Net as an Agent".
Revenues are recognized when equipment is delivered and accepted by the
customer. Title to equipment passes when equipment is accepted by the customer.

Allowance for Doubtful Accounts

   An allowance for doubtful accounts is established in amounts considered to be
appropriate  based  primarily upon the Company's past credit loss experience and
an evaluation of potential losses in the receivables outstanding.

Other Investments

   In accordance with SFAS No. 115, "Accounting for Certain Investments in Debt
and Equity Securities," the Company classifies its marketable equity securities
as available-for-sale securities, which are accounted for at fair value with
unrealized gains and losses excluded from earnings and reported in accumulated
other comprehensive income (loss). The cost of securities sold is determined
based on average cost.

   The Company reviews the fair value of available-for-sale securities on a
regular basis to determine if the fair value of any individual security has
declined below its cost and if such decline is other than temporary. If the
decline in value is judged to be other than temporary, the cost basis of the
investment is written down to fair value. Other than temporary declines in value
are determined taking into consideration the extent of decline in fair value,
the length of time that the decline in fair value below cost has existed and
events that might accelerate the recognition of impairment. The resulting
realized loss is included in the consolidated statements of income in the period
in which the decline is deemed to be other than temporary.




   Non-marketable equity securities are carried at cost as fair value is not
readily determinable. If the value of a security is estimated to have declined
and such decline is judged to be other than temporary, the security is written
down to the fair value. Determination of impairment is based on the
consideration of such factors as operating results, business plans and change in
the regulatory, economic or technological environment of the investees. For
purposes of computing an impairment loss, fair value is determined as the
Company's interest in the net assets of investees.

Inventories

   Inventories consist mainly of network equipment purchased for resale and
work-in-process for development of Internet network systems. Network equipment
purchased for resale is stated at the lower of cost, which is determined by the
average-cost method, or market. Work-in-process for development of network
systems is stated at the lower of actual production costs, including overhead
cost, or market. Inventories are reviewed periodically and items considered to
be slow-moving or obsolete are written down to their estimated net realizable
value.

Leases

   Capital leases, which meet specific criteria noted in SFAS No.13, "Accounting
for Leases", are capitalized at the inception of the lease at the present value
of the minimum lease payments. All other leases are accounted for as operating
leases. Lease payments for capital leases are apportioned to interest expense
and a reduction of the lease liability so as to achieve a constant rate of
interest on the remaining balance of the liability. Operating lease payments are
recognized as an expense on a straight-line basis over the lease term.

Property and Equipment

   Property and equipment are recorded at cost. Depreciation and amortization of
property and equipment, including purchased software and capitalized leases, are
computed principally using the straight-line method based on either the
estimated useful lives of assets or the lease period, whichever is shorter.

   The useful lives for depreciation and amortization by major asset classes are
as follows:


                                                                          
----------------------------------------------------------------------------------------------------
                                                                    Range of useful lives
----------------------------------------------------------------------------------------------------
  Data communications, office and other equipment                          2 to 15 years
  Leasehold improvements                                                   3 to 15 years
  Purchased software                                                             5 years
  Capitalized leases                                                        4 to 7 years
----------------------------------------------------------------------------------------------------


Impairment of Long-lived Assets

   Long-lived assets consist principally of property and equipment, including
those items leased under capital leases. The Company evaluates the impairment of
long-lived assets whenever events or changes in circumstances indicate that the
carrying amount of an asset may not be recoverable in accordance with SFAS No.
144, "Accounting for the Impairment or Disposal of Long-Lived Assets." There
were no impairment losses for long-lived assets for the interim period ended
September 30, 2007.

Goodwill and Intangible Assets

   In accordance with SFAS No. 142, "Goodwill and Other Intangible Assets,"
goodwill (including equity-method goodwill) and intangible assets that are
deemed to have indefinite useful lives are not amortized, but are subject to
impairment testing. Impairment testing is performed annually or more frequently
if events or changes in circumstances indicate that the asset might be impaired.
The Company performs annual impairment tests on March 31.

Pension and Severance Indemnities Plans

   The Company has pensions plans and, or severance indemnities plans. The cost
of the pension plans and severance indemnities plans are accrued based on
amounts determined using actuarial methods.

   On September 29, 2006, the FASB issued SFAS No.158, "Employers' Accounting
for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB
statements No. 87, 88, 106, and 132(R)." ("SFAS No. 158"). SFAS No. 158 requires
an employer that sponsors one or more defined benefit pension plans or other
postretirement plans to 1) recognize the funded status of a plan, measured as
the difference between plan assets at fair value and the benefit obligation, in
balance sheet; 2) recognize in shareholders' equity as a component of
accumulated other comprehensive income, net of tax, the gains or losses and
prior service costs or credits that arise during the period but are not yet
recognized as components of net periodic benefit cost; 3) measure defined
benefit plan assets and obligations as of the date of the employers' fiscal
year-end balance sheet; and 4) disclose in the notes to the financial statements
additional information about the effects on net periodic benefit cost for the
next fiscal year that arise from delayed recognition of the gains or losses,
prior service costs or credits, and transition asset or obligation.



   The Company  adopted SFAS No. 158 effective  March 31, 2007.  The adoption of
SFAS No. 158 resulted in a decrease in total shareholders' equity of JPY 111,731
thousand as of March 31, 2007.

Income Taxes

   The provision for income taxes is based on earnings before income taxes and
includes the effects of temporary differences between assets and liabilities
recognized for financial reporting purposes and income tax purposes and
operating loss carryforwards. Valuation allowances are provided against deferred
tax assets when it is more likely than not that a tax benefit will not be
realized.

Foreign Currency Transaction

   Foreign currency financial statements have been translated in accordance with
SFAS No. 52, "Foreign Currency Translation." Pursuant to this statement, the
assets and liabilities of a foreign subsidiary and an equity method investee are
translated into Japanese yen at the respective period-end exchange rates. All
income and expense accounts are translated at average rates of exchange. The
resulting translation adjustments are included in accumulated other
comprehensive income.

   Foreign currency assets and liabilities, which consist substantially of cash
denominated in U.S. dollars, are stated at the amount as computed by using
period-end exchange rates and the resulting transaction gain or loss is
recognized in earnings.

Derivative Financial Instruments

   All derivatives are recorded at fair value as either asset or liabilities in
the balance sheet in accordance with SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," as amended by SFAS No. 138 and No. 149
(collectively, "SFAS No. 133"). In accordance with SFAS No. 133, the Company
designated interest swap contracts as a hedge of the variability of cash flows
to be paid related to interest on floating rate borrowings (cash flow hedge) and
the effective portion of the derivative's gain or loss is initially reported as
a component of other comprehensive income and subsequently reclassified into
earnings when the underlying transaction affects earnings. The ineffective
portion of the gain or loss is reported in earnings immediately.

   The Company enters into contracts to hedge interest rate risks and does not
enter into contracts or utilize derivatives for trading purposes.

Stock-based Compensation

   On April 1, 2006, the Company adopted SFAS No. 123R, "Share-Based Payment"
and the related interpretations, which requires compensation expense for stock
options and other share-based payments to be measured and recorded based on the
instruments' fair value, by using the modified prospective application method.
SFAS No. 123R requires recognizing expenses for share-based payments granted
prior to the adoption date equal to the fair value of unvested amounts over the
remaining requisite service recognized. As all existing granted stock-based
awards of the Company have vested, the adoption of SFAS No.123R did not have any
impact on the Company's consolidated financial position or results of
operations.

Research and Development

   Research and development costs are expensed as incurred.

Advertising

   Advertising costs are expensed as incurred and are recorded in "Sales and
marketing."

Basic and Diluted Net Income per Common Share

   Basic net income per common  share is computed by dividing  net income by the
weighted-average number of shares of common stock outstanding during the period.
Diluted net income per common share  reflects the potential  dilutive  effect of
stock options and convertible  bonds. (See "NET INCOME PER SHARE (Unaudited)" in
the latter part of this document for details.)



Other Comprehensive Income (Loss)

   Other comprehensive income (loss) consists of translation adjustments
resulting from the translation of financial statements of a foreign subsidiary,
unrealized gains or losses on available-for-sale securities and gains or losses
on cash flow hedging derivative instruments.

Segment Reporting

   SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," establishes standards for reporting information about operating
segments. Operating segments are defined as components of an enterprise that
engage in business activities from which it may earn revenues and incur expense
and for which separate financial information is available that is evaluated
regularly by the chief operation decision maker in deciding how to allocate
resources and in assessing performance.

   The Company provides a comprehensive range of network solutions to meet its
customers' needs by cross-selling a variety of services, including Internet
connectivity services, VAS, SI and sales of network-related equipment. The
Company's chief operating decision maker, who is the Company's Chief Executive
Officer, regularly reviews the revenue and cost of sales on a consolidated basis
and makes decisions regarding how to allocate resources and assess performance
based on a single operating unit.

New Accounting Standards

   In June 2006, the FASB issued FIN No. 48, "Accounting for Uncertainty in
Income Taxes, an interpretation of FASB statement No. 109" ("FIN No. 48") which
clarifies the accounting for uncertainty in income tax recognized in an
enterprise's financial statements in accordance with SFAS No. 109, "Accounting
for Income Taxes." This interpretation prescribes a recognition threshold and
measurement attribute for the financial statement recognition and measurement of
a tax position taken or expected to be taken in a tax return. This
interpretation also provides guidance on derecognition, classification,
interest, and penalties, accounting in interim periods, disclosure, and
transition. The Company adapted FIN No. 48 from the interim period ended
September 30, 2007. The adoption of FIN No. 48 did not have a material effect
upon the Company's financial position or results of operations.

   In September 2006, the FASB issued SFAS No.157, "Fair Value Measurements"
which defines fair value, establishes a framework for measuring fair value in
generally accepted accounting principles, and expands disclosures about fair
value measurements. This Statement applies under other accounting pronouncements
that require or permit fair value measurements and is effective for fiscal years
beginning after November 15, 2007. The Company is currently evaluating the
impact of adopting this Statement.

   In February 2007, the FASB issued SFAS No. 159, "The Fair Value Option for
Financial Assets and Financial Liabilities," which permits entities to choose to
measure many financial instruments and certain other items at fair value. This
Statement's objective is to improve financial reporting by providing entities
with the opportunity to mitigate volatility in reported earnings caused by
measuring related assets and liabilities differently without having to apply
complex hedge accounting provisions.

   SFAS No. 159 is effective for fiscal years beginning after November 15, 2007.
The Company is currently evaluating the impact of adopting this Statement.

---------------------------------------------------------------------------------------------------------------------



   For the interim period ended September 30, 2007 and 2006, the number of the
potentially dilutive shares excluded from the computation of diluted net income
per share because the exercise prices of the options were greater than the
average market price of the common shares was 950 shares.

SUBSEQUENT EVENTS (Unaudited)
-----------------------------

On October 31, 2007, IIJ made an additional investment of JPY 485,000 thousand
to TN (common stock: JPY 22, 500 thousand), its equity method investee. As a
result, TN became IIJ's 66.9% owned consolidated subsidiary.

On November 12, 2007, IIJ's board of directors resolved to pay a cash
dividend  of JPY 750 per share of  common  stock for the  interim  period  ended
September  30, 2007  (record  date:  September  30,  2007,  the total  amount of
dividend payments: JPY 154,859 thousand).
