What TBM does

TBM (東洋ビルメンテナンス株式会社, Toyo Building Maintenance Co., Ltd.) is a Tokyo-headquartered, privately held integrated building maintenance company founded in 1973 to manage the former Sanwa Bank (now MUFG Bank) Tokyo head office. The company delivers five core service lines to Japanese enterprise and institutional customers: (1) building integrated management covering equipment, security, cleaning, and environmental health; (2) facility support including diagnostics, long-term maintenance planning, energy-saving consulting, and PM/CM coordination; (3) equipment construction and renovation (electrical, HVAC, plumbing, fire protection); (4) sustainable business services, notably mega-solar O&M (51 sites / ~280.5 MW managed) and electrical safety inspection; and (5) parking and bicycle parking facility design, construction, and mechanical-to-flat conversion. Two proprietary technology platforms anchor operations: the BACS-104 Building Automation Control System (24/7 remote monitoring from Tokyo and Osaka centers) and SoleiL Station (centralized solar plant monitoring with weather, webcam, and generation analytics), supported by two 2016 business model patents in mega-solar O&M.

TBM employs 823 staff (1,256 group) including 534 technicians holding 4,263 total professional certifications, and manages approximately 1,266 facilities across office buildings, financial institution branches (~882), data centers (~11), mega-solar plants (51), and condominiums. Revenue model combines recurring managed services contracts (long-term, relationship-based) with project-based equipment construction and one-time parking renovation work. The company is anchored by MUFG Bank as its largest shareholder and a major client, and by Toyo Real Estate Group as second-largest shareholder; FY March 2026 revenue reached ¥18.1 billion.

Revenue mix spans office/financial (~70%+ of named facilities), hyperscale data centers (entry September 2021), renewable energy infrastructure, and condominium parking infrastructure. Distribution is exclusively direct enterprise sales via relationship-based field sales and the corporate website. Supporting infrastructure includes the proprietary TBM TECHS training facility (Yachiyo, Chiba, completed June 2023) and TBM Academy, which offers public certification exam preparation and security management courses (¥6,000–¥110,000 per course) that double as both revenue streams and talent pipeline development. TBM is ISO 9001 / 14001 / 45001 certified and holds 13-category Special Type 1 Construction Business licensing.
