What Taisei Engineering does
Taisei Engineering Co., Ltd. (タイセイエンジニアリング株式会社) is a privately-held Japanese information services company founded in December 1974, headquartered in Setagaya, Tokyo, with a secondary CNT Branch in Inzai, Chiba. The company operates across three service divisions: data entry BPO, custom system development, and RFID solutions, serving primarily major Japanese insurance groups and Toshiba Group manufacturers.
The core data entry business processes insurance applications, government forms, and enterprise documents using a proprietary KIS Association Input method (a 2-stroke kanji input system) combined with dual-entry verify-input processes and master-based validation to achieve financial institution-grade accuracy. The company has layered AI-OCR-based automated document extraction on top of this manual operation, plus adjacent BPO offerings such as Commuter Car Management Outsourcing. The system development division provides custom software, SES (System Engineering Service) contracts, legacy design document reconstruction, and embedded systems (notably railway signal control) for Toshiba Group subsidiaries and other major Japanese enterprises. The RFID division offers hands-free semi-active tag solutions for access control, wayfinding, energy management, and theme park applications.
Commercially, Taisei Engineering sells exclusively through direct enterprise field sales relationships. The firm is labor-intensive: 51-100 employees, registered capital of only ¥20 million, no external funding, and no disclosed revenue. Pricing is quote-based for client services, while engineer salaries are publicly disclosed for recruitment (¥207K-¥430K monthly). The customer base is highly concentrated among long-tenured Japanese enterprise clients, with several relationships spanning 40+ years. Privacy Mark certification (JIS Q 15001) has been maintained continuously since August 2005, and the company holds a worker dispatch license obtained in February 2019.
