What 株式会社トラスト does
株式会社トラスト (Trust Co., Ltd.) is a Yokohama-headquartered home renovation contractor founded in 2002 that specializes in natural-materials construction — diatomaceous earth (珪藻土), solid wood, and lime plaster — across full apartment, detached-house, public-housing, and commercial renovations in the Kanagawa and greater Tokyo area. It operates a vertically integrated model that includes in-house custom manufacturing of kitchens, vanities, and furniture, plus a seismic reinforcement service line delivered through specialist partners. Project tickets range from roughly ¥500K on the small end to over ¥21M on the premium end, with the firm claiming category leadership in Yokohama natural-materials renovation.
The business model is a one-stop service stack: site survey and free consultation, design and construction, custom-manufactured interior components, warranty servicing, and embedded financing via partners ORICO and Flat 35. It bundles these with a used-property purchase × renovation package and a dedicated real-estate-investor segment, leveraging a 57-employee headcount under founder/CEO 塚越岳人. Geographic reach is anchored in Yokohama Aoba-ku and extended into Tokyo and Saitama through a franchise partner (DSI, 有限会社ディー・エス・アイ). The firm is privately held, owner-operated, and has accumulated HomePro industry satisfaction recognition over more than two decades of operation.
