EXHIBIT 99.1

Notice Regarding the Scheduled Delisting of American Depositary Shares from the NASDAQ Exchange

TOKYO, April 01, 2019 (GLOBE NEWSWIRE) -- Internet Initiative Japan Inc. ("IIJ", NASDAQ: IIJI, TSE1: 3774) announced that further to its announcement on February 7, 2019 regarding its intention of delisting from the NASDAQ Exchange (“NASDAQ”), IIJ has notified the NASDAQ on April 1, 2019 (Eastern Time in the U.S.) that IIJ will apply for voluntary delisting of its American Depositaries Shares (“ADSs”) from the NASDAQ. Please see below for details.

Reasons for Delisting
IIJ listed its ADSs on the NASDAQ in August 1999. While it was quite rare in Japan for Internet-related companies to be listed, Internet-related companies were expanding their businesses through capital market financing in the U.S.A. Since the listing, along with business expansion, IIJ has made efforts to enhance disclosure for shareholders and investors, to comply with the disclosure requirements of the U.S. Securities laws and regulations, to prepare consolidated financial statements in accordance with the generally accepted accounting principles in the U.S.A. and to establish internal controls in accordance with the Sarbanes-Oxley Act of 2002. Meanwhile, the external environment has changed as indicated by the increase in trading volume of Japanese stocks through stock exchanges in Japan by overseas investors due to the internationalization of Japanese financial and capital markets. In addition to the market changes, our small trading volume of ADSs meets the criteria for terminating registration. Therefore, IIJ has decided to apply for delisting of its ADSs from the NASDAQ and for termination of registration of ADSs with the U.S. Securities and Exchange Commission (the “SEC”) under the Exchange Act.

After Delisting
Even after delisting its ADSs from the NASDAQ, IIJ intends to maintain its American Depositary Receipt Program in the U.S.A. through a depositary bank; therefore, IIJ anticipates that its ADSs should continue to be traded in the U.S. on the over-the-counter market. Same as now, a depositary bank will continue to handle conversion from ADS to our ordinary share traded in the Tokyo Stock Exchange which will still be available through the conversion ratio and process such as cash dividend payment.

While IIJ’s reporting obligations under the Exchange Act (including the obligation to file annual reports on Form 20-F) should be terminated, IIJ will continue to disclose financial statements and other information as translation in English on its IR website in a timely manner to ensure that its overseas shareholders and investors should continue to have appropriate information about IIJ.
