Overview
Tokai Software Development Co., Ltd. (株式会社東海ソフト開発) is a Japanese information-technology services company headquartered in Shibuya-ku, Tokyo. It was established in July 1992 in Shinagawa-ku, Tokyo, with capital of 50 million yen, and has since grown into a systems-development and IT-solutions provider whose work is concentrated in two fields it explicitly names as its business pillars: education and medical care. The company is closely tied to the Tokai University group: its shareholders are Tokai Educational Industry Co., Ltd. (68%) and the Tokai University Educational System (32%), and its early development department was opened inside Tokai University's Faculty of Development Engineering. The company's service portfolio centers on the planning, construction, and improvement of IT environments for schools, universities, hospitals, and clinics. Its official site highlights a track record of environment improvement and system construction for many educational institutions — including Tokai University's universities and high schools — and for many medical institutions, including Tokai University Hospital. It also provides internet services as a registered Type 2 telecommunications carrier and is registered as a certified office for the Japan Medical Association's standard receipt (ORCA) software, reflecting its focus on medical accounting and clinical systems. Tokai Software Development operates from its Tokyo head office, with a history of branch and project offices in Kanagawa and Shizuoka prefectures. It has been a privately held company throughout its existence, with two shareholders and capital of 50 million yen. In late 2025 and early 2026 the company disclosed a ransomware attack and published a series of notices and updates about its response, an incident that has been a prominent item in its public communications.
History
Tokai Software Development Co., Ltd. was established in July 1992 in Shinagawa-ku, Tokyo, with capital of 50 million yen. The following month, in August 1992, the company opened a development department inside the Faculty of Development Engineering of Tokai University, an arrangement that anchored its early growth in the university's academic and technical environment. In April 1995 the company hired its first regular employee, a graduate of the Faculty of Development Engineering's Department of Information and Communication Engineering. In August 1996 the head office was relocated to Shibuya-ku, Tokyo, where it remains. In April 1997 the company opened the Shimizu branch office in Shimizu-ku, Shizuoka City, Shizuoka Prefecture, and launched its first website on the internet. In August 1999 the Shimizu branch was moved to Hase, Atsugi City, Kanagawa Prefecture, and renamed the Atsugi office. In April 2000 the company acquired its own domain and opened its website at tokaisoftdev.co.jp. In June 2002 the company amended its articles of incorporation to add the sale of goods and changed the term of its auditors to four years. In April 2003 the Numazu Development Department was relocated to Shimizu-ku, Shizuoka City as the Shizuoka office, and the company began sales operations with "schools" and "medical care" as the pillars of its business. In December 2003 the Shizuoka office was registered as a certified office for the Japan Medical Association's standard receipt (ORCA) software. In April 2004 the company obtained Type 2 telecommunications carrier status and began internet services. In March 2006 the Atsugi office was also registered as a certified office for the Japan Medical Association's standard receipt software. In May 2012 the Shizuoka office was relocated to Mishima City, Shizuoka Prefecture. In June 2013 the company added specified worker dispatching services to its articles of incorporation. In June 2014 the Atsugi office was relocated to Onna, Atsugi City, Kanagawa Prefecture. In March 2017 the Shizuoka office was closed, and in April 2017 the company substantially renewed its website. As of its corporate profile, the company has capital of 50 million yen, 1,000 issued shares out of 4,000 authorized, and two shareholders: Tokai Educational Industry Co., Ltd. with 680 shares (68%) and the Tokai University Educational System with 320 shares (32%). Its main bank is Mitsubishi UFJ Bank's Hon-Atsugi branch, with additional relationships at Resona Bank's Isehara branch and Japan Post Bank's Isehara branch. In late 2025 and early 2026 the company disclosed a ransomware attack and issued a series of reports on its response.
