The Daiichi Information Systems

What The Daiichi Information Systems does

The Daiichi Information Systems Co., Ltd. (DIS) is an independent Japanese system integrator founded in July 1972 and headquartered in the DIS Ebisu Building in Shibuya, Tokyo. The company delivers one-stop IT services across the full system lifecycle — consulting, application development, infrastructure construction, and 24/7 system operation and maintenance — to a concentrated base of large Japanese enterprise and public-sector clients. Its primary verticals are financial services (banks, trust banks, insurance), manufacturing, and government, with anchor relationships including the Mizuho Financial Group, Meiji Yasuda Life Insurance, Mitsubishi Electric, and the Tokyo Metropolitan Government. Service delivery is conducted on-site at client locations across the Kanto region (Tokyo, Kanagawa, Saitama).

DIS's revenue mix combines traditional professional services (application development, infrastructure design/build, IT solutions, IT services) with managed-services recurring revenue (24/7 system operation and maintenance, including approximately 120 mission-critical business systems under non-stop operation for financial clients). Pricing is project-based with multi-year contract cadence and custom quotations, reflecting its B2B enterprise field-sales motion. The group has 837 employees as of April 1, 2026, operates a wholly-owned nearshore development subsidiary (TBK System Engineering) in Koriyama, Fukushima, and reported FY March 2026 standalone revenue of ¥88.3 billion (approximately $590M USD) and consolidated group revenue of ¥98.3 billion (approximately $655M USD).

On top of its traditional SI base, DIS has layered a portfolio of proprietary AI products and services: AI Dashboard (serverless predictive analytics on AWS), Mail Beacon-1 (Azure OpenAI-based email analysis for executive risk/opportunity detection), and the Azure OpenAI Construction Service (packaged GenAI deployment with RAG). These were launched or expanded between December 2023 and March 2025, alongside the PC-LCM managed service for PC lifecycle management. The company is privately held with no disclosed external venture or private equity backing, retains founder-family control under President Kojima Yoshihisa, and has grown organically for over 50 years. Its distribution model is direct enterprise field sales with no channel partners, and its geographic footprint is domestic Japan with no disclosed international operations.
