What TSC does

TSC Co., Ltd. (株式会社ティーエスシー) is a Japanese IT services company founded in November 1991 and headquartered in Machida City, Tokyo. Since June 2025 it has operated as a subsidiary of Synergy K Co., Ltd. (株式会社シナジーK, HDC). TSC delivers custom software development across three integrated service lines: (1) measurement and control systems for factory automation and industrial inspection, including a proprietary in-house tool that enables program-less configuration for multi-product production lines; (2) web and business application development using Java, .NET, Angular, TypeScript, and Python; and (3) middleware and platform infrastructure design covering Windows Server, Linux, Solaris, Active Directory, virtualization, and cloud migrations. The company supports diverse legacy and real-time operating environments, including MS-DOS, Windows 95-era systems, N88BASIC modernization, and RTOS deployments.

TSC generates revenue through project-based custom development engagements under fixed-price and time-and-materials contracts, delivered directly by its approximately 39-person engineering team. Its go-to-market is direct enterprise sales supported by long-term referral relationships, with channel reinforcement from Fujitsu Technical Partner (2021) and Core Partner (2024) certifications. Customers span manufacturing, government and public-sector subsidy administration, insurance cooperative systems, and construction — including major manufacturers, 農林水産省 (Ministry of Agriculture, Forestry and Fisheries), the 補助金事務局 (Subsidy Administration Office), 損保業界共同利用, and 大手建設会社. The company emphasizes engineer development, evidenced by 125+ annual holidays, six consecutive years of 健康経営優良法人 recognition, Privacy Mark certification, Kurumin certification pursuit, and METI Business Continuity Plan certification.
