ISE

What ISE does

ISE (株式会社情報システム工学 / Information System Engineering Co., Ltd.) is a Tokyo-headquartered independent Japanese system integrator founded in July 1979. The firm delivers custom software development, IT consulting, and Application Management Outsourcing (AMO) to large enterprise clients across distribution and retail (supermarkets, wholesalers, department stores), financial services (mega banks, life insurance, credit card issuers), marketing and media, manufacturing, and government and public sectors. Operations are concentrated in the Greater Tokyo area, with a smaller China-based AMO operation established in 2012.

The company's core proprietary technology is the CI Framework, a component library for building cross-device business application screens that operate consistently on PCs, tablets, and smartphones. Delivery is organized around the MAC specialist system (Manager, Application Specialist, Consultant) supported by a Foster mentorship program, with engineering teams typically embedded on-site at client premises. The company is ISO/IEC 27001:2005 certified and holds 198 million JPY in stated capital. A wholly-owned subsidiary, ISE Research Institute, concentrates activity in higher-growth adjacencies including DX consulting, AI development (NLP, computer vision, speech recognition, predictive analytics, generative AI), cloud migration, COBOL-to-Java legacy migration, and life-sciences IT.

ISE's business model is project-based professional services: revenue is generated through consulting engagements, custom development projects, and recurring AMO contracts billed largely on a time-and-materials basis, with supplemental license income from the CI Framework. Disclosed revenue for the fiscal year ending March 2026 was 7.4 billion JPY (approximately US$49M at ~150 JPY/USD), produced by 306 employees as of April 1, 2026 — an average of roughly 24 million JPY per head, consistent with Japanese SI labor rates. The company is privately held, with no disclosed external investors or IPO plans.
