About Us

Corporate History

We were first established in June 1986 as a wholly-owned subsidiary of The Sumitomo Trust and Banking Co., Ltd. (currently Sumitomo Mitsui Trust Bank, Limited) under the corporate name Sumishin Business Service Co., Ltd. (the corporate name was changed to Sumishin Office Service Co., Ltd. in September 2004) for the purpose of providing The Sumitomo Trust and Banking Co., Ltd. with office administrative services.

In March 2006, The Sumitomo Trust and Banking Co., Ltd. and SBI Holdings, Inc. entered into an agreement in order to leverage their expertise in the banking and finance industries to create an internet bank. In April 2006, The Sumitomo Trust and Banking Co., Ltd. and SBI Holdings, Inc. created a joint venture, each acquiring 50% ownership interest in us, and subsequently changed our corporate name to Sumishin SBI Net Bank Research Company, Ltd.

In September 2007, we obtained our banking business license from the Prime Minister pursuant to the Banking Act, were renamed SBI Sumishin Net Bank, Ltd. and commenced operations. In October 2007, we connected to the “Zengin System” and “BANCS” Japanese interbank payment systems. Since 2008, we have expanded into various product lines and services including financial brokerage services, life and car insurance products, mortgage and credit card lending and foreign exchange trading services.

Our subsidiaries under our digital banking segment are SBI Sumishin Net Bank Card Co., Ltd., established in July 2009, and Yuryo Loan, Ltd., acquired in March 2021.
