Heisei Kensetsu

What Heisei Kensetsu does

Heisei Kensetsu (株式会社平成建設) is a Japanese regional construction company founded in 2006 and headquartered in Numazu, Shizuoka Prefecture. It operates across three prefectures — Shizuoka, Kanagawa and Tokyo — through seven branches and showrooms (Numazu HQ, Shizuoka, Setagaya, Hino, Yokohama, Atsugi and Fujisawa), serving individual homeowners, property investors, medical professionals, and corporate clients. The service portfolio spans custom-built homes, renovation, rental apartment development, medical facility opening support (DoctorS' Assist), commercial facility construction, and real estate brokerage and management. The company has won multiple Good Design Awards (notably 2018 and 2025 for 杢巧舘 and COURETTE) and maintains cultural engagement assets including the Heisei Memorial Museum Gallery and the Heisei Art Award partnership with Tokyo University of the Arts.

The company executes projects across multiple structural methods — SE構法 (membership in the NCN network), traditional 在来工法, RC造 (reinforced concrete) and S造 (steel) — and operates an in-house design, manufacturing and construction model that supports integrated quality control. Specialized product lines include the Maison La KUU female-oriented rental apartment brand, the HTS35 guaranteed-rental system for property investors, and DoctorS' Assist, which provides end-to-end clinic opening support from land search and financing through construction, staffing and post-opening management. Recruitment of craftsmen (大工育成) is positioned as a core competency and brand pillar.

Revenue is generated primarily through one-time construction contracts and real estate brokerage/management fees. The go-to-market combines physical showroom visits, on-site construction tours, a multi-channel digital presence, and partnership referrals (notably with regional accounting firms for medical facility openings). Customer acquisition is relationship-led rather than algorithmic, and pricing follows project-based contracting rather than subscription or usage-based models. The private, non-funded status of the company means growth has been funded internally through retained earnings rather than external capital.
