Kashiwabara

What Kashiwabara does

Kashiwabara Group (株式会社カシワバラ・コーポレーション, Kashiwabara Corporation) is a privately-held Japanese diversified housing and real estate services conglomerate founded in 1949 and headquartered in Tokyo, with the Iwakuni headquarters in Yamaguchi Prefecture and offices across Japan (Osaka regional HQ plus sales offices in Sapporo, Sendai, Nagoya, Fukuoka, and Okinawa). The group operates 1,001–5,000 employees and serves both individual consumers—home buyers, homeowners, condominium residents and associations—and corporate clients requiring construction, renovation, infrastructure maintenance, demolition, and property development services. Kashiwabara is led by Representative Director Shinsuke Kashiwabara (柏原 伸介), and no external institutional investment or public listing was identified.

The group's product surface covers the full property lifecycle and is delivered through wholly-owned subsidiaries, each anchored to a distinct service vertical: Kashiwabara Ground (real estate development and custom/spec home sales in Tokyo's Jonan area), Tokyo Gumi (custom wood-frame residential construction), Kashiwabara Days (condominium management and maintenance), Kashiwabara Assist (mortgage origination and refinancing, including products targeted at freelancers, expatriates and single parents), Kashiwabara Hands (hospitality and accommodation development, operating the YAWN YARD garden-stay concept and THE OAK private machiya rental brand), Kashiwabara Partner (insurance), Kashiwabara Connect (telecommunications), Original Text (creative and communication design), Ogura Gumi (demolition), and Nippon no Mado (wooden window sash manufacturing). Service lines for corporate clients include infrastructure maintenance, large-scale and ultra-high-rise condominium repair, building/facility renovation, architectural design and construction, demolition, and investment condominium development. Underpinning the technical offering is over 70 years of accumulated painting and coating expertise, used for infrastructure maintenance and applied to large-scale building refurbishment where specialized scaffolding and scheduling for ultra-high-rise structures are competitive differentiators.

Revenue is generated through a mix of one-time project contracts (custom home construction, renovation, demolition, architectural design), recurring service contracts (condominium management, infrastructure maintenance, mortgage servicing), and transaction-based income (hotel operations, telecom reselling, insurance brokerage). Pricing is contact-based and project-specific rather than publicly disclosed. In September 2025 the group broadened its recurring-revenue base by acquiring 100% of Chintai Keiei Support Co., Ltd. (賃貸経営サポート), which manages 3,695 rental units as of August 2025, primarily in the Osaka area. Distribution is direct, leveraging the physical office footprint nationwide supplemented by the corporate website and participation in industry events such as the BREX Housing, Architecture & Real Estate Comprehensive Expo.
