What Haseko does

Haseko Corporation (株式会社長谷工コーポレーション, TSE: 1808) is Japan's leading condominium construction company, holding the #1 position in cumulative condominium construction volume nationally with dominant shares in the Tokyo Metropolitan Area and Kansai region. Founded in 1937 and headquartered in Minato-ku, Tokyo, the company operates an integrated design-build model applied to 95% of its condominium projects, underpinned by its proprietary Haseko版BIM — a 3D Building Information Modeling system tailored specifically for condominium design and construction workflows.

The company's revenue is generated across six principal streams: condominium construction (general contracting), condominium and real estate development (sale of built inventory), condominium management (recurring fees from managing associations and landlords — 520,000+ units under group management), large-scale repair and renovation, senior living operations, and overseas development in Hawaii and Vietnam. Its business model combines transactional project revenue (development, construction, renovation) with recurring annuity-like revenue (management, senior living, insurance distribution through Haseko Links). Customers span individual homebuyers, condominium associations, and corporate clients including developers and businesses requiring commercial real estate or employee housing. The integrated group network of 15+ wholly-owned subsidiaries covers the entire residential lifecycle from land acquisition through long-term management.

Haseko's go-to-market is sales-led and B2B/B2C hybrid, with condominiums sold directly through group sales subsidiaries (Haseko HFD, Haseko Sumai, Haseko Home) and corporate real estate handled through dedicated teams. Technology investments include the proprietary Haseko版BIM platform (used across nearly all projects), WinActor RPA and DXSuite AI-OCR for office automation (delivered via subsidiary Haseko Links, rebranded from Haseko Systems in April 2026), and VR/AR tools for property sales visualization. The company is currently executing a medium-term evolution plan launched in April 2025 to expand overseas operations, evidenced by its April 2026 minority investment in U.S. operator Trinsic Residential Group — its first operating platform investment in the U.S. since re-entering that market in 2019.
