                           Year Ending March 31, 2007

  Continuous Increase in Revenues and Profits due to Strong Business
                              Environment


    TOKYO--(BUSINESS WIRE)--Nov. 9, 2006--Internet Initiative Japan
Inc. (Nasdaq: IIJI, Tokyo Stock Exchange Mothers: 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, 2007 ("FY2006").(1)

    Highlights of Second Quarter FY2006 Results

    --  Revenue totaled JPY 14,007 million ($118.7 million), an
        increase of 17.4% from 2Q05.

    --  Operating income was JPY 811 million ($6.9 million), an
        increase of 59.9% from 2Q05.

    --  Net income was JPY 2,120 million ($18.0 million), an increase
        of 111.9% from 2Q05.

    Target for FY2006(2)

    --  As announced on November 2, 2006, IIJ revised its original
        targets for FY2006 that were announced on May 10, 2006. The
        revised targets are JPY 56 billion for revenues, JPY 3.2
        billion for operating income, JPY 5 billion for income before
        income tax expense (benefit) and JPY 5 billion for net income.

    Overview of 2nd Quarter of FY2006 Financial Results and Business
Outlook(2)

    "We had a very strong second quarter, with revenues and profits
increasing compared to the same period last year," said Koichi Suzuki,
President and CEO of IIJ. "The business environment in IIJ's key
markets remained quite strong this quarter. Corporate customers
continued to shift to higher speed connectivity services due to the
steady expansion of corporate network usage. We also continued to see
strong demand for outsourcing services because corporate customers
faced an increase of network-related security incidents and an overall
shortage of Internet engineers. Corporate customers also increased the
construction of internal information technology networks based on
Internet technology. For Internet connectivity services, revenues
turned to increase compared to the previous quarter, despite the
continued stiff competition. The shift of customers to relatively
lower-priced broadband services has almost completed and customers of
IP Services, which are mainly used for Internet connectivity at
corporate headquarters and data centers, shifted to higher-speed
connections. Additionally, the number of contracts for broadband
services for the connection of corporate branch offices and shops via
Internet VPN increased. For value-added services, revenues increased
in a number of areas, including e-mail related services that provide
virus-fighting functions, isolate spam and record outgoing and
incoming e-mails comprehensively, security-related services, Internet
VPN related services and data center services. For systems
integration, revenues rose mainly due to an increase in projects for
companies that selected us to construct corporate information
technology networks that use Internet technology, systems related to
online business expansion and to enhance existing systems. In
addition, we introduced several new e-mail and security-related
products this quarter and will continue to try to capitalize on the
growing demand in out target markets."

    "According to the favorable financial results for the first half
of FY2006, we announced revised targets for FY2006 on November 2,
2006," said Akihisa Watai, CFO of IIJ. "We revised our revenue target
for FY2006 from JPY 55 billion to JPY 56 billion. We maintain our
target for operating income of JPY 3.2 billion for FY2006, since our
annual revenues and operating income are largely influenced by the
financial results in the fourth quarter, which is very strong
historically due to seasonal factors mainly related to corporate
spending on systems integration projects, and those figures tend to
fluctuate greatly in that period."

services, affected by an increase in demand for outsourcing services.

    SI revenues increased 39.9% to JPY 7,221 million in 2Q06 compared
to 2Q05. The increase was mainly due to an increase in one-time
revenues from network design, construction and consultation and a
steady increase in monthly recurring revenues from network operation
and maintenance.

    Equipment sales revenues were JPY 630 million in 2Q06, a decrease
of 37.0% compared to 2Q05.

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


    Cost of Connectivity and VAS revenues was JPY 5,254 million in
2Q06, an increase of 5.3% compared to 2Q05.

    Cost of SI revenues was JPY 5,611 million in 2Q06, an increase of
43.2% compared to 2Q05. The increase was mainly due to an increase in
revenues from systems integration projects.

    Cost of Equipment Sales revenues was JPY 583 million in 2Q06, a
decrease of 39.7% compared to 2Q05.

    Sales and marketing expenses were JPY 843 million in 2Q06, an
increase of 5.4% compared to 2Q05. The increase was mainly due to an
increase in advertising expenses and personnel expenses.

    General and administrative expenses were JPY 862 million in 2Q06,
an increase of 23.3% compared to 2Q05. The increase was mainly due to
an increase in personnel expenses.

    Operating income

    Operating income was JPY 811 million in 2Q06, an increase of 59.9%
compared to 2Q05. The increase was mainly due to the increase in
revenues from relatively higher-margin value-added services and
systems integration.

    Other income and others

    Other income in 2Q06 was JPY 334 million, a decrease of 43.4% from
JPY 590 million in 2Q05. The decrease was mainly due to a decrease in
the gain from sale of available-for-sale securities, which is largely
a reflection of the decrease in the value of the securities held due
to market price fluctuations. The gain from the sale of
available-for-sale securities in 2Q06 was JPY 445 million.

    Income tax benefit in 2Q06 was JPY 1,109 million, compared to
income tax expense of JPY 44 million in 2Q05. The benefit was mainly
because of deferred tax benefits of JPY 1,266 million resulting from a
release of valuation allowance against deferred income tax assets
related to tax operating loss carryforwards and others. Minority
interests in earnings of subsidiaries in 2Q06 was JPY 82 million.
Equity in net loss of equity method investees in 2Q06 was JPY 52
million.

    Net income was JPY 2,120 million in 2Q06, an increase of 111.9%
compared to 2Q05.

    2nd Quarter FY2006 Business Review

    Analysis by Service

    Connectivity and Value-added Services

    For dedicated access services, customers for IP Services, which
are mainly used for corporate headquarters and data centers, continued
to shift to higher speed bandwidth for IP Services. The number of
contracts for broadband services also continued to increase
substantially compared to 2Q05, mainly due to the increasing demand
for services that connect branch offices and shops through Internet
VPN.

    The number of contracts for dedicated access services increased by
3,410 to 16,112 compared to 2Q05. Total contracted bandwidth increased
by 102.2Gbps to 253.2Gbps compared to 2Q05.

    Dedicated access service revenues were JPY 2,687 million, a
decrease of 0.3% compared to 2Q05. The decrease is mainly related to a
decrease of JPY 234 million in interconnection revenues between IIJ's
network and Asia Internet Holding Co., Ltd. ("AIH"), IIJ's former
equity method investee, because AIH was merged into IIJ in October
2005.

    Dial-up access service revenues were JPY 606 million in 2Q06, a
decrease of 11.2% compared to 2Q05, mainly due to a decrease in
revenues from services for individual customers, such as IIJ4U, as
well as the discontinuance of services of certain large customer to
which we provided our services as OEM.

    VAS revenues were JPY 1,906 million in 2Q06, an increase of 30.7%
compared to 2Q05. The increase was due to an increase in revenues from
various types of services, such as e-mail, security and Internet VPN
related services and data center services.

    Other revenues were JPY 957 million in 2Q06, an increase of 2.9%
compared to 2Q05.

    As a result, revenues from Internet connectivity and value-added
services in 2Q06 were JPY 6,156 million, an increase of 6.7% compared
to 2Q05. The gross margin for Internet connectivity and value-added
services in 2Q06 was JPY 901 million, an increase of 15.7% compared to
2Q05. The gross margin ratio in 2Q06 was 14.6%, compared to 13.5% in
2Q05.

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

2. Management Policy

(1) Basic Management Policy

   IIJ's basic management policy is to lead the development of the information
society in Japan based on Internet technologies and contribute to the creation
of new markets and the development of industries. IIJ intends to fulfill its
social responsibility as a company by realizing this policy and by continuously
increasing its value.

(2) Basic Policy on the Distribution of Profits

   While it regards the payment of dividends to shareholders as an important
management issue, IIJ did not pay dividends for the fiscal year ended March 31,
2006, since it recorded an accumulated deficit in its non-consolidated financial
statements for the fiscal year ended March 31, 2006. IIJ proposed the reductions
of additional paid-in capital and common stock in its non-consolidated financial
statements to the general shareholders' meeting held in June 2006 and the
reductions were approved. As a result, IIJ's accumulated deficit in its
non-consolidated financial statements was eliminated effective August 4, 2006.
IIJ expects to have retained earnings in its non-consolidated financial
statements for the fiscal year ending March 31, 2007. While it intends to pay
dividends to shareholders stably and continuously, IIJ has not decided if it
will pay dividends or has not decided about the level of payment of dividends
for the fiscal year ending March 31, 2007 at this moment, since a large portion
of net income is raised from gain from sale of available-for-sale securities and
it pays little tax due to tax operating loss carryforwards.

(3) Policies regarding the Reduction in the Size of the Investment Unit

   IIJ believes that reducing the size of the investment unit is one of the
effective ways to expand its investor base and increase the liquidity of its
shares. IIJ intends to take it into account in the future, by closely watching
the level of the stock price, the number of shareholders, the effectiveness of
expenditures and the stock market environment and other items in general.

(4) Business Indicators as Targets

   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 and general and administrative
expenditures, while closely watching its revenue growth ratio, gross margin
ratio, operating margin ratio and other figures.

(5) Medium and Long-term Business Strategies

   The IIJ Group expects that the requirements by its customers for usage of
network systems will become more advanced and diversified, as broadband expands
in Japan and usage of Internet by corporate customers and public organizations
increases. The IIJ Group speculates that demands for reliable network systems
and outsourcing of network systems by corporate customers and public
organizations that are its main customers will continue to increase, and the IIJ
Group regards the current market trend as an opportunity for our growth. On the
other hand, the IIJ Group expects that competition in the fields of Internet
connectivity and value-added services and systems integration will become more
intense. Although price competition is high for Internet connectivity services,
the IIJ Group recognizes that it is possible for it to differentiate itself from
other companies by providing connectivity services along with value-added
services and systems integration. The IIJ Group believes it to be important for
its business development to actively promote research and development on new
technologies related to Internet and continuously provide total solutions that
are reliable, highly value-added and competitive.

(6) Issues that IIJ should Address

   Although the environment surrounding the IIJ Group is becoming more favorable
and its results of operations are improving, it is important for the IIJ Group
to recognize the expansion of network usage by enterprises and public
organizations as a market opportunity, continue to provide reliable and
competitive services and enhance the business structure of IIJ and the IIJ
Group. In the fiscal year ending March 31, 2007, the IIJ Group will continue its
efforts to increase revenues and profits, promote its research and development,
introduce new services, investigate business partnerships including investments
and enhance its corporate governance.

   It is also important for the IIJ Group to attract and educate excellent
engineers and sales personnel to maintain its growth in the future, and the IIJ
Group is especially focusing on educating recent graduates. The IIJ Group
recruited 41 recent graduates (including 29 new graduates recruited by IIJ)
during the fiscal year ended March 31, 2006. 82 recent graduates joined the IIJ
Group in April 2006 (including 49 new graduates recruited by IIJ).

other Companies

29.7% as of September 30, 2006, including its indirect ownership. However, IIJ's
sales activities are not affected by NTT's ownership in IIJ and IIJ is
maintaining its management independence.

   IIJ entered into a subscription agreement with NTT in which IIJ granted to
NTT pre-emptive rights to subscribe to its pro rata portion of any future
issuances of shares by IIJ upon its completion of its private placement to NTT
in 2003. NTT did not exercise the rights upon IIJ's issuance of new shares of
common stock for public offering when it listed on the Mothers market of the
Tokyo Stock Exchange in December 2005.

c. Personal Relationships with the Parent Company and other Companies and their
Group Companies

   IIJ's board of directors consists of 13 members including 4 outside
directors. Within the directors, Takashi Hiroi is an employee of NTT.

   Takashi Hiroi, an outside director (part-time director) of IIJ, is an

of its access circuits, and services provided by NTT Communications for a
significant portion of its domestic and international backbones. The amount paid
to NTT East and West, and NTT Communications for their telecommunication
circuits was JPY 431,304 thousand and JPY 2,359,319 thousand, respectively for
the interim period ended September 30, 2006.

business practices, and there is no special contract made in relation to the
investment by NTT Group, as the business transactions existed before NTT Group
became our largest shareholder.

3. Results of Operations and Financial Conditions

(1) Consolidated Results of Operations in the Interim Period Ended
September 30, 2006 (from April 1, 2006 to September 30, 2006)

a. Overview of Financial Results

   For the interim period ended September 30, 2006, the business environment
surrounding IIJ continued to be very favorable. Corporate customers shifted to
higher speed services for Internet connectivity services as they increase usage
of networks, the demands for outsourcing services increased due to an increase
of security incidents and an overall shortage of Internet related engineers, and
the construction of corporate information network systems utilizing Internet
technologies increased. As a result, the revenues and profits increased compared
to the interim period ended September 30, 2005.

   For Internet connectivity services, revenues turned to increase quarter over
quarter basis, as the shift of customers to lower-priced services caused by the
expansion of broadband services has almost finished, customers shifted to higher
speed services for IP Service, which is mainly used for Internet connections for
corporate headquarters and data centers, and the contracts for broadband
services, which are used for the connection between corporate branch offices and
shops increased.

   For value-added services ("VAS"), revenues increased overall, such as e-mail
related services which provide comprehensive functions of deletion of computer
viruses, isolation of spam, recording of incoming and outgoing e-mails and
others, security-related services, Internet VPN related services and data center
services.

   For systems integration ("SI"), revenues increased due to an increase in
revenues from the construction of corporate information network systems
utilizing Internet technology, construction of systems for the expansion of
businesses over the Internet by customers and enhancement of existing systems
and others.

   In the interim period ended September 30, 2006, the IIJ Group continued its
efforts to capture the increase in demand mentioned above mainly by enhancing
line-ups of VAS. The IIJ Group began to provide "IIJ Managed VPN PRO", "IIJ
Secure MX Service", "IIJ Managed Firewall Service", "IIJ Document Exchange
Service" and "iiMail" and others.

   As a result, for the IIJ Group's consolidated results of operation for the
interim period ended September 30, 2006, total revenues amounted to JPY 26,444
million, an increase of 21.3% compared to the interim period ended September 30,
2005, operating income amounted to JPY 1,370 million, an increase of 81.8%
compared to the interim period ended September 30, 2005, income before income
tax expense (benefit) amounted to JPY 2,144 million, an increase of 20.5%
compared to the interim period ended September 30, 2005 and net income amounted
to JPY 2,854 million, an increase of 75.8% compared to the interim period ended
September 30, 2005.

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


   Connectivity and VAS revenues were JPY 12,019 million for the interim period
ended September 30, 2006, an increase of 4.2% compared to the interim period
ended September 30, 2005. The increase is mainly due to an increase in revenues
from VAS, which was affected by an increase in demand for outsourcing services.



   SI revenues increased by 47.2% from the interim period ended September 30,
2005 to JPY 13,253 million for the interim period ended September 30, 2006. The
increase was mainly due to a significant increase in one-time revenues from
network design, construction and consultation and a continuously steady increase
in monthly recurring revenues from network systems operation and maintenance.

   Equipment sales revenues were JPY 1,172 million for the interim period ended
September 30, 2006, a decrease of 8.0% compared to the interim period ended

c. Analysis by Service

1) Connectivity and VAS

   For dedicated access services, customers shifted to higher speed services for
IP service, which are mainly used for Internet connection for corporate
headquarters and data centers and the number of contracts for broadband
services, which are used for the connection of corporate operational sites
increased. However, revenues from dedicated access service revenues were JPY
5,303 million for the interim period ended September 30, 2006, a decrease of
2.6% compared to the interim period ended September 30, 2005. The decrease is
mainly due to a decrease of revenues of JPY 468 million from the interconnection
of IIJ's network with AIH, IIJ's former equity method investee, which was caused
by the merger of AIH into IIJ.

   Dial-up access service revenues were JPY 1,213 million for the interim period
ended September 30, 2006, a decrease of 12.2% compared to the interim period
ended September 30, 2005. The decrease is mainly due to the discontinuance of
services of certain large customer to which IIJ provided its services as OEM and
the decrease in revenues from services fro individual customers, such as IIJ4U.

   VAS revenues were JPY 3,647 million for the interim period ended September
30, 2006, an increase of 28.1% compared to the interim period ended September,
2005. The increase was mainly due to an increase in revenues from various types
of services, such as e-mail, security and Internet VPN related services and data
center services.

   Other revenues were JPY 1,857 million for the interim period ended September
30, 2006, a decrease of 0.3% compared to the interim period ended September 30,
2005.

   As a result, revenues from connectivity and VAS for the interim period ended
September 30, 2006 were JPY 12,019 million, an increase of 4.2% compared to the
interim period ended September 30, 2005. The gross margin for connectivity and
VAS was JPY 1,695 million for the interim period ended September 30, 2006, an
increase of 7.2% compared to the interim period ended September 30, 2005. The
gross margin ratio for connectivity and VAS was 14.1% for the interim period
ended September 30, 2006.

Significant Basic Items for Preparation of Consolidated Financial Statements for
--------------------------------------------------------------------------------
the Interim Period Ended September 30, 2006
-------------------------------------------

   The Terminology,  Form, and Preparation Methods for the Consolidated
Financial Statements for the Interim Period Ended September 30, 2006

   The consolidated financial statements for the interim period ended September
30, 2006 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 81 "provisions for the terminology,
form, and preparation methods for interim consolidated financial statements"
(Ministry of Finance, ordinance No. 24, 1999).

   IIJ registered issuance of ADRs under the United States Securities and
Exchange Commission ("the United States SEC") and list IIJ's 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.

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.

Consolidation

   The consolidated financial statements for the interim period ended September
30, 2006 include the accounts of IIJ and all of its subsidiaries, Net Care, Inc.
("Net Care"), IIJ Technology Inc. ("IIJ Technology"), IIJ Financial Systems Inc.
("IIJ FS"), Net Chart Japan Inc. ("Net Chart") and IIJ America, Inc. ("IIJ
America"), which have interim periods ending September 30, except for IIJ
America. 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, 2006 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 for the
interim period ended September 30, 2006. Significant 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 generally accepted
accounting principles 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
impairment loss on advances to equity method investees, valuation allowances for
deferred tax assets, allowance for doubtful accounts, and estimated lives of
fixed assets. Actual results could differ from those estimates.

Revenue Recognition

   Revenues from customer connectivity services consist principally of dedicated
Internet access services and dial-up Internet access services. Dedicated
Internet access services represent full-line IP services and standard-level IP
services (T1 Standard and IIJ FiberAccess/F Service). Dial-up Internet access
services are provided to both enterprises and individuals (IIJ4U). The term of
these contracts is one year for dedicated Internet access services and generally
one month for dial-up Internet access services. All these services are billed
and recognized monthly on a straight-line basis.

   Value-added service revenues consist principally of sales of various Internet
access-related services such as firewall services. Value-added services also
include monthly fees from data center services such as housing, monitoring, and
security services. Other revenues under connectivity and value-added services
consist principally of call-center customer support and Wide-area Ethernet
services to construct networks that connect multiple operational sites for
customers. 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
value-added services are deferred and recognized over the contract period.

   Systems integration revenues consist principally of the consultation of
Internet network systems, design, development or construction and related
maintenance, monitoring and other operating services. The period for the
development of the systems or designs is less than one year and revenues are
recognized when network systems and equipment are delivered and accepted by the
customer under the completed contract method. The development of the Internet
network systems or design includes multiple element arrangements such as
consultation, planning, systems design, and construction services, and equipment
and software purchased from third parties. 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. Maintenance,
monitoring, and operating service revenues are recognized ratably over the
separate contract period, which is generally for one year.

   Systems integration service is subject to the Emerging Issues Task Force
("EITF") of the Financial Accounting Standards Board ("FASB") Issue No. 00-21,
"Revenue Arrangements with Multiple Deliverables" which was adopted as of April
1, 2004.

   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 equipments are delivered and accepted by the
customer.

Cash and Cash Equivalents

   Cash and cash equivalents include time deposits and readily marketable
securities with original maturities of three months or less.

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," all marketable equity securities are classified 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 investments on a
regular basis to determine if the fair value of any individual investment 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 operations in the
period in which the decline was 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. 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
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 loss for long-lived assets for the interim period ended
September 30, 2005, and the interim period ended September 30, 2006 and the
fiscal year ended March 31, 2006.

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 pension 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, in accordance with SFAS No. 87,
"Employers' Accounting for Pensions".

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 assets
that are not likely to be realized.

Foreign Currency Transactions

   Foreign currency assets and liabilities, which consist substantially of cash
and accounts payable for connectivity leases to international carriers
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 Sprits

   On August 4, 2005, IIJ's board of directors approved a five-for-one split of
IIJ's common stock. Shareholders of record on August 31, 2005 received an
additional common share. The stock split was effective on October 11, 2005. In
order to reflect this split, information pertaining to the number of shares of
common stock and net income per share has been restated in the accompanying
financial statements and related notes.

Stock-based Compensation

   The Company accounts for stock-based compensation in accordance with SFAS No.
123R, "Accounting for Stock-Based Compensation" from the interim period ended
September 30, 2006. SFAS No. 123R requires compensation expense for stock
options and other share-based payment to be measured and recorded based on the
instruments' fair value. The Company adopted SFAS No. 123R and the related FASB
Staff Positions on April 1, 2006 by using modified prospective application,
which requires recognizing expenses for options granted prior to the adoption
date equal to the fair value of unvested amounts over the remaining vesting
period. The portion of these options' fair value attributable to vested awards
prior to the adoption of SFAS No. 123R is never 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 and Advertising

   Research and development and advertising costs are expensed as incurred.

Advertising

   Advertising costs are expensed as incurred.

Basic and Diluted Net Income per Share

   Basic net income per 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 share reflects the potential dilutive effect of stock
options. (See note 8 - Basic and Diluted Net Income per Share)

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
engages 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, value-added services, systems integration and sales of
network-related equipment. The Company's chief operating decision maker, who is
IIJ's President and Representative Director, 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 FASB Interpretation ("FIN") No. 48, "Accounting
for Uncertainty in Income Taxes," which clarifies the accounting for uncertainty
in income taxes 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 quarterly financial
statements, disclosure, and transition. FIN No. 48 is effective for fiscal years
beginning after December 15, 2006. The Company is currently evaluating the
impact of adopting this interpretation.



   In September 2006, the FASB issued SFAS No. 157, "Fair Value Measurements."
SFAS No. 157 establishes a framework for measuring fair value in applying
generally accepted accounting principles, and expands disclosures about fair
value measurements. SFAS No. 157 is effective for financial statements issued
for fiscal years beginning after November 15, 2007. The Company is currently
evaluating the impact of adopting SFAS No. 157.

   In September 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 to recognize the overfunded or underfunded status of their benefit
plans as an asset or liability in its balance sheet and to recognize changes in
that funded status in the year in which the changes occur as a component of
other comprehensive income. SFAS No. 158 is effective for fiscal years ended
after December 15, 2006 except for the change in measurement date which is
effective as of the beginning of the fiscal year beginning after December 15,
2008. The adoption of SFAS No. 158 is not expected to impact the Company's
consolidated financial condition and results of operations.
