Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block] | 1. DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Internet Initiative Japan Inc. (“IIJ,” a Japanese corporation) was founded in December 1992 March 31, 2018, 26.9% Certain Significant Risks and Uncertainties The Company relies on telecommunications carriers for a significant portion of its network backbone, on regional NTT subsidiaries, electric power companies and their affiliates for local connections to customers and NTT DoCoMo Inc. (“NTT Docomo”) for mobile connectivity as an MVNO. Currently, NTT Communications Corporation, a wholly owned subsidiary of NTT, and NTT Docomo are major providers of network infrastructure for the Company. The Company believes that its use of multiple carriers and suppliers significantly mitigates the risk of damages from service disruptions. However, any disruption of telecommunication services could have an adverse effect on operating results. Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of accounts receivable. The Company’s management believes that the risks associated with accounts receivable are mitigated by the large number of customers comprising its customer base and its credit line control. The Company also conducts an evaluation of a new customer’s financial condition at the inception of a transaction and continuously monitors delays in payment for each customer.

These services also include the installation of software as well as configuration and installation of hardware. ・ Software―we resell third ・ Hardware―we also resell third third ・ Monitoring and operating services―we monitor our customer's network activity and Internet connectivity to detect and report problems.

The system construction services are generally delivered over a three not Monitoring, operating, and hardware and software maintenance services generally commence once our customers have accepted the systems, and contract periods are generally from one five For multiple-element arrangements that include system construction services, hardware, software essential to the hardware product’s functionality and undelivered non-software services (e.g., monitoring and operating services), the Company allocates revenue to all deliverables based on their relative selling prices. The Company uses a hierarchy to determine the selling price to be used for allocating revenue to the deliverables: (i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third may The method used to account for each unit and the period over which each unit of accounting is recognized are as follows: ・ Revenue allocated to system construction services is accounted for using contract accounting. System construction service revenues, which are generally completed within three 605 35 25 92 not ・ Revenue related to the hardware and software essential to the hardware product’s functionality is not not ・ Revenue related to undelivered non-software services (monitoring, operating and hardware maintenance services) is recognized on a straight-line basis over the contract period. The Company also enters into multiple-element arrangements for system integration services that include software not 985 605, Equipment sales revenues are recognized when equipment is delivered and accepted by the customer. The Company evaluates whether it is appropriate to record the gross amount of revenues and related costs or the net amount earned in reporting system construction services and equipment sales, depending on whether the Company functions as the principal or agent. The ATM operation business revenues consist primarily of commissions for each withdrawing transaction with the use of ATMs. The ATM commission collected from each withdrawal is aggregated every month and recognized as ATM operation revenues. Revenue is recognized net of consumption tax collected from customers and subsequently remitted to governmental authorities. Cash and Cash Equivalents— three Allowance for Doubtful Accounts— Other Investments— 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, the financial condition and near-term prospects of the issuer, and the Company’s intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value and events that might accelerate the recognition of impairment. For debt securities for which the declines are deemed to be other-than-temporary and there is no not not not Non-marketable equity securities are carried at cost as fair value is not not, first may ・ A significant deterioration in the earnings performance or business prospects of the investee. ・ A significant adverse change in the regulatory, economic, or technological environment of the investee. ・ A significant adverse change in the general market condition of either the geographic area or the industry in which the investee operates. ・ A recent example of the new issuance of a security, in which the issue price is less than our cost. The Company estimates the fair value of the non-marketable equity securities when an impairment indicator is present. The fair value is determined as a result of considering various unobservable inputs which are available to the Company, including expectation of future income of the investees, net asset value of the investees, and material unrealized losses to be considered in assets and liabilities held by the investees. The Company recognizes impairment of non-marketable equity securities when the fair value is below the carrying amount and the decline in fair value is considered to be other-than-temporary.

Plan assets, including life insurance pooled investment portfolios, consist of Japanese and U.S. government bonds, other debt securities and marketable equity securities. Life insurance pooled investment portfolios are managed by an insurance company and guarantee a minimum rate of return. The Company’s investment strategy for the plan assets is to manage the assets in order to pay retirement benefits to plan participants from the Company over the life of the plans. This is accomplished by identifying and managing the exposure to various market risks, and diversifying investments in various asset classes based on a portfolio determined by the insurance company in order to maximize long-term rate of return, while considering the liquidity needs of the plans. The plan is permitted to use derivative instruments only for the purpose of hedging. Both margin trading and real estate investments are prohibited in principle. The Company mitigates the credit risk of investments by establishing guidelines with the insurance company. These guidelines are monitored periodically by the Company for compliance. The projected allocation of the plan assets managed by the insurance company is developed in consideration of the expected long-term investment returns for each category of the plan assets.

Investment, Policy [Policy Text Block] | Other Investments— 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, the financial condition and near-term prospects of the issuer, and the Company’s intent and ability to retain the investment for a period of time sufficient to allow for any anticipated recovery in market value and events that might accelerate the recognition of impairment.

The Company estimates the fair value of the non-marketable equity securities when an impairment indicator is present. The fair value is determined as a result of considering various unobservable inputs which are available to the Company, including expectation of future income of the investees, net asset value of the investees, and material unrealized losses to be considered in assets and liabilities held by the investees. The Company recognizes impairment of non-marketable equity securities when the fair value is below the carrying amount and the decline in fair value is considered to be other-than-temporary. |
