EIS

What EIS does

EIS (株式会社英揮情報システム, Eiki Information System Co., Ltd.) is a privately held Japanese IT services company founded in June 1984 and headquartered in Minato-ku, Tokyo. For 41 years the firm has provided end-to-end IT solutions spanning system design, build, development, operations, and consulting, organized into four service pillars: Open System Solutions (e-commerce, travel reservation, EDI/cloud migration), Financial Solutions (life-insurance DWH, securities front-end, bank loan processing, mainframe support), Infrastructure Foundation Solutions (mail systems, server operations, data analytics), and a newly added Generative AI Solutions line built on Azure, Flask, and ChatGPT.

The company's technology stack combines legacy mainframe expertise (COBOL, AIX, HP-UX, DB2) with modern open-system development (Java, .NET, Python, JavaScript, C#) and multi-cloud delivery across AWS, Azure, and GCP. Delivery is anchored by project managers and project leaders who remain hands-on alongside engineers - the firm's so-called "co-playing" model - and staffed engagements include PM, PL, SE, and programmer personnel provision to client sites.

EIS earns revenue primarily through professional-services engagements on time-and-materials and project bases with mid-to-large Japanese enterprises, concentrated in financial services (banks, securities, insurance) and spanning retail, logistics, and manufacturing. Disclosed FY2025 revenue (September 2025 fiscal year end) is ¥2.48 billion on a headcount of approximately 127 employees plus roughly 120 partner/contractor engineers. The firm is an owner-operated, founder-led Kabushiki Kaisha (registered capital ¥50 million) without external institutional investors and holds Privacy Mark, METI system-audit and information-security-audit registrations, and the All-Ministry Unified Qualification that together enable participation in regulated and government-sector work.
