What TOSHO COMPUTER SYSTEMS does

TOSHO COMPUTER SYSTEMS Co., Ltd. (TCS, 株式会社東証コンピュータシステム) is a Japanese private IT services company founded in 1961 as a spin-off of the Tokyo Stock Exchange's computing division (originally Tokyo Securities Computing Center, renamed in 1986). The company builds and operates mission-critical IT infrastructure for the Japanese securities industry, anchored by GigaDRMS Exchange — described as the No.1 exchange terminal system in Japan with direct connectivity to arrowhead, J-GATE, CONNEQTOR, and other Japanese trading venues — and GigaDRMS Dealing, a high-speed securities dealing system. Its back-office stack includes NEWCOSMO for order-to-settlement processing and a JASDEC/BOJ post-trade package supporting T+1 straight-through-processing readiness.

TCS generates revenue across five streams: (1) system development and integration for securities and financial institutions (professional services), (2) ASP/SaaS delivery of GigaDRMS, NEWCOSMO, irVision, and security services from FISC-compliant data centers (subscription/recurring), (3) Security SUITE bundled cybersecurity offerings covering ~40 financial institutions with subscription or per-service billing, (4) IR and market-data SaaS (irVision, stock gadgets, market/timely disclosure data APIs) for listed companies, and (5) IT outsourcing including server custody, 24/7 system monitoring, and solution cloud-ization services. The customer base spans 103 securities companies, listed enterprises (NYK Line, Bandai Namco Holdings, JFE Holdings, Konica Minolta), credit unions, regional banks, IFA firms, and regulatory bodies such as JPX and JASDEC. The go-to-market is direct enterprise sales supplemented by third-party vendor partnerships (Radware, Cybereason, CyCraft Japan, Hammock, Aeria, DDS) and channel partners (CMC Solutions for the Nagoya region). Registered capital is ¥400M; major shareholders include FUJISOFT Inc. and the Tokyo Stock Exchange. The company operates a 319-person workforce across Tokyo (Toranomon headquarters, relocated December 2023) and Osaka (Kansai Service Center).

• NTT DATA Japan: Major Japanese system integrator with a sizeable financial services practice delivering trading, banking, and settlement platforms — directly comparable to TCS's systems integration and managed services for financial institutions.
• Fujitsu Limited: One of Japan's largest IT vendors with broad financial services offerings; sibling of FUJISOFT (TCS's parent) within the Fujitsu/related group, and competes for large brokerage transformation programs.
• SCSK Corporation: Major Japanese IT services firm serving financial institutions with systems integration and managed services — overlapping with TCS's mid-market securities IT offerings and broader financial vertical presence.
• Nihon Unisys, Ltd. Japanese IT services firm with established financial services business covering banking and securities customers — competing broadly with TCS for system integration and managed services engagements in Japanese financial vertical.

Direct peers

• Bravi Inc. Japanese financial IT vendor focused on securities back-office and order management systems; directly competes with TCS's NEWCOSMO in serving Japanese broker-dealers' middle- and back-office needs.

Others

• JPX (Japan Exchange Group): Operator of Tokyo Stock Exchange and a major TCS shareholder/customer; not a competitor but a closely intertwined ecosystem participant whose technology decisions directly affect TCS's exchange terminal franchise.
