OB System

What OB System does

O.B.System Inc. (株式会社オビーシステム, TSE Standard: 5576) is a Japanese independent systems integrator founded in 1972 in Osaka, providing custom software development, systems integration, and digital transformation (DX) consulting across three service lines: Financial Services (megabank, regional bank, internet bank, insurance, securities, credit), Industrial/Distribution (manufacturing, distribution, medical, microcontroller applications, IoT), and Social/Public (electric power ICT, social infrastructure, satellite communications, public/media/cultural/education). Approximately 70% of revenue is generated through long-standing channel partnerships with Hitachi Group (40+ years) and Mitsubishi Electric Software (30+ years), with the remaining revenue derived from direct enterprise sales and the company's two proprietary medical software packages: CLIP®, a clinical testing system with AI-augmented voice interface launched in 2000 and last updated as CLIP Ver5.1 AI in March 2025, and MEX-Plus®, a health examination support system launched in 2005.

The company operates from three sites — Osaka (headquarters, 1972), Tokyo (headquarters, 2003), and Nagoya (Chubu branch, 2017) — and runs a wholly-owned subsidiary structure with the April 2024 acquisition of Human & Technology (Sapporo) and the May 2025 acquisition of Green Cat (Tokyo). Consolidated revenue for FY2026 (year ended March 2026) was ¥8.65 billion with operating profit of ¥672M, supported by 665 consolidated employees as of April 2026. OB System is accredited under ISO/IEC 27001:2022 (since 2019), ISO 9001:2015 (since 2021), and Japan's Privacy Mark (JIS Q 15001, since 2007), and has received five consecutive years (2022–2026) of Health Management Outstanding Company designation from METI and the Japan Health Council.

The business model combines project-based professional services (system integration consulting, design, development, and maintenance) with subscription-style recurring revenue from proprietary medical software sales, customization, and maintenance. The firm's January 2026 establishment of an AX (AI Transformation) Promotion Office — combined with the integration of its IT Innovation Business into the Financial Services division in April 2026 — signals a strategic push to monetize AI-augmented capabilities across its established SIer distribution channels, though no proprietary foundation-model research or frontier AI development capability is disclosed.
