Goko Tatemono

What Goko Tatemono does

Goko Tatemono (互光建物管理株式会社, Goko Tatemono Kanri Co., Ltd.) is a privately held Japanese building management company founded in May 1951 as Shinko Cleaner Co., Ltd., reorganized in 1958, and renamed to its current form in 1964. Headquartered in Osaka with a registered capital of ¥80 million (authorized ¥150 million), the company operates as the flagship operating entity of the Goko Group (互光グループ), a diversified nationwide network of 7 regional building management subsidiaries covering Hokkaido, Tohoku, Tokyo, Chubu, Osaka, Kobe, and Fukuoka. The company directly employs 1,832 people as of January 2026 and is led by President Asada Akihiro, with ownership concentrated in the founding Asada family.

The company's core business is integrated facility management across five product lines: Building Management (cleaning, equipment, security, facility management for offices, factories, hospitals, schools), Hotel Management, Store/Retail Management, Condominium Management (300 associations and 26,930 units for the parent entity; 1,112 associations and 67,506 units group-wide), and Real Estate Management (leasing, brokerage, rent collection). These services are underwritten by UNICORN-G, a proprietary 24-hour centralized building management system launched in 1977 that combines equipment monitoring, disaster prevention, security, telephone response, and video surveillance, staffed by qualified equipment technicians. The company also operates a condominium renovation add-on service and worker dispatch operations. Enterprise customers include NTT Facilities, Daiwa Living, Suntory, Panasonic Group, Kubota, Mizuho Trust Bank, and JR East Hotels, with a diversified long-tail of condominium associations.

Goko Tatemono operates a sales-led, consultation-based go-to-market: free on-site surveys, customized proposals, and management committee approvals. The GTM is entirely direct — services are delivered through the company's own offices and employed staff across all major Japanese regions, with no third-party distribution. Pricing is not publicly disclosed and is negotiated per building based on size and service scope. Certifications include ISO 14001:2015 (environmental management), Privacy Mark under JIS Q 15001 (first obtained 2006, renewed through 2020), and multiple sector-specific government registrations for condominium management, real estate transactions, security, and specialized construction.
