Taiyo

What Taiyo does

Taiyo (タイヨー株式会社) is a Tokyo-based, family-owned private holding company founded in May 1985 that operates a diversified security and facility services platform across Japan's Kanto and Kansai regions. Its core business is human-based guarding services delivered through ten service lines: facility security, traffic direction, event security, attendant staff, parking lot security, patrol, consulting, highway regulation, train watching, and bodyguard services. The company serves commercial facilities, construction sites, event venues, parking operators, and highway operators including NEXCO East Japan.

Taiyo extends its platform into adjacent revenue streams: mechanical/systems security as an authorized dealer of ALSOK equipment (surveillance cameras, facial recognition, IC card access), building maintenance (cleaning, equipment operation), general construction (highway landscaping and pavement repair under a 特-6 license), and staffing dispatch. In June 2025 the company added a new product line by becoming a certified sales partner for Mitsui Sumitomo Insurance's MS LifeConnect AI smart camera system, introducing computer vision and anomaly detection into its offering. A separate "security with hospitality" initiative targets healthcare, childcare, and eldercare facilities using dual-qualified staff.

Go-to-market is sales-led, executed through a network of 8 branches and 2 satellite offices (Katsushika, Shibuya, Wangan, Matsudo, Keiyo, Saitama, Yokohama, Osaka, Kyoto satellite). Pricing is quote-based for B2B contracts with shift-based or hourly billing for individual clients. The company is family-controlled by the Oomura family, with 748 employees as of May 2025 (632 security guards, 63 operations, 55 in-office), capital of 50 million yen, and no external institutional investors.

Directly comparable in core guarding services to Taiyo, but operates at vastly greater scale across all of Japan and has proprietary technology and government contracts Taiyo cannot match.
• Secom (セコム): Japan's flagship security conglomerate, combining manned guarding with the largest proprietary online security network in Japan (COCC). Highly comparable to Taiyo on guarding services but with nationwide coverage, in-house R&D, and significant international operations.
• Nippon Building Service (日本建物管理): Larger Japanese building management and facilities services firm offering cleaning, equipment operation, and integrated facility management. Overlaps with Taiyo's Building Maintenance Division on commercial office cleaning and maintenance.
