What b corporation does

b corporation Co., Ltd. (b コーポレーション株式会社) is a Japan-based B2B services firm founded in September 2004 that delivers commercial-space construction projects for multi-location restaurant and retail chains. It operates as the services arm of the bwd Group, sitting alongside four sister entities — bwd Holdings, B&I, Bond Shoji, and Wood Building Materials — in a vertically integrated construction-services platform. The firm is headquartered in Shibuya, Tokyo, with additional offices in Sapporo, Nagoya, Osaka, and Fukuoka, and it extends execution into Southeast Asia through group affiliate B&I Vietnam.

The company's core offering is a four-line service stack: design, project management, procurement and supply, and construction, packaged for chains that need to roll out or refresh stores at scale. Documented clients and projects include Kyoto Yakiniku Tendan, Saizeriya, Doutor Coffee, Lox's Hamburger, Royal Host, and the Vietnam-based brand "beyond." Production is standardized on Autodesk Revit for BIM and Matterport for 3D site scanning, with the digital model used as the connective tissue across the four service lines from initial survey through as-built documentation. The business model is contract-based: revenue is tied to per-store rollouts, multi-location renovations, and group procurement for chain clients, with no consumer-facing product or recurring SaaS line.

No public revenue, headcount, or backlog disclosures were available in the input. The firm is privately held under bwd Holdings and operates as a sub-consolidated services unit rather than a standalone reporting entity. Pricing is project-by-project, the customer mix is concentrated in national-scale Japanese chain operators in F&B and small-format retail, and the leadership currently rests with Representative Director 小黒 義幸 (Oguro Yoshiyuki), appointed in 2022, alongside Managing Director 奥田 一隆 (Okuda Kazutaka).
