What Tama Home does

Tama Home Co., Ltd. is a publicly listed Japanese residential homebuilder (TSE Prime, ticker 1419) founded on June 3, 1998, and headquartered in Minato-ku, Tokyo. The company designs, constructs, and sells custom wooden-frame single-family houses across all 47 prefectures of Japan through a network of more than 200 model house showrooms, supported by Happy Home Fair events and an online reservation system. Its product lineup spans six named series — Dai-Anshin-no-Ie (the flagship bestseller), Dai-Anshin PREMIUM, GALLERIART, Kibou-no-Ie, Wabisai, and Green Eco — at construction price points from ¥20M to ¥40M+. The company differentiates on seismic safety, evidenced by a full-scale vibration test conducted at Japan's E-Defense facility in October 2017 demonstrating that its Dai-Anshin-no-Ie homes withstand seismic intensity 7 without collapse, and standard seismic resistance grade 3 certification.

Tama Home generates revenue primarily through one-time custom home construction contracts, complemented by completed-house sales in subdivisions, renovation/remodeling, condominium sales, sublease rental properties, and an insurance agency line. Pricing is uniformly one-time/perpetual license per project, with financing support provided through affiliate Tama Finance Co., Ltd. The company targets individual Japanese homebuyers — from young couples to multi-generational households — with sub-segments for ready-move buyers, renovation customers, and real estate investors. A vertically adjacent ecosystem spans post-sale services (Happy Life Club, warranty/support), insurance, advertising (Tama AD), lifestyle services (Tama Living), and overseas affiliates in Singapore (Tama Global Investments) and Vietnam (Tama Son Thanh).

As of FY2025 (ending May 31, 2025), Tama Home reported sales of ¥200,800 million with a workforce of 3,272 employees. Ownership remains family-anchored: TAMAX Co., Ltd. holds 39.29%, and four Tamaki family members collectively hold approximately 15%. The Master Trust Bank of Japan holds 7.15% as the largest institutional investor. The company does not hold treasury stock and has 29,455,800 shares outstanding across 64,775 shareholders. Reported financial trend data over the prior four years indicates significant revenue and EBITDA compression, consistent with a cyclical Japanese housing market and input cost pressure.
