History
Tokai Information Systems was founded in November 1973 in Tokiwa-cho, Hamamatsu, according to the company's official history page. The following year, in 1974, its Data Department began operations, and in 1978 the Systems Department started business, establishing the two core service lines of data processing and systems work. Through the 1980s the company continued as a regional IT services provider in Hamamatsu. In 1992 it began developing client/server (C/S) systems, reflecting the shift in enterprise computing away from mainframe-centric architectures. In 2002 it started developing web systems, moving with the spread of internet-based business applications. In 2005 the Data Department ended its in-house operations, with the work continuing through partner outsourcing thereafter. In 2010 the company started its application development business and began using cloud services. In 2011 it launched its Solutions business. In 2015 data-entry operations ended, completing the transition away from the original data-processing business. In 2018 the company began migrating its internal systems to the cloud, and in 2020 it started telework arrangements for development and general affairs staff, a change accelerated by the broader shift to remote work. The company marked its 50th anniversary in 2023, having grown from a data-processing shop into a provider of consulting, system development, system operation and equipment sales. By the mid-2020s the company presented itself as a one-stop partner for clients' IT needs, from planning and consulting through development and operation, with a focus on digital transformation using AI and IoT and on supplying development resources to clients. Its official site lists case studies in areas such as food-service DX, sports science and the funeral business, and it continues to recruit new graduates and mid-career staff. It remains headquartered in Hamamatsu, now in the Chuo 1-chome district, and holds ISO/IEC 27001:2013 certification for information security management.
