What Zero Corporation does

Zero Corporation (株式会社ゼロ・コーポレーション), founded in June 1981 and headquartered in Kyoto, is a privately-held Japanese homebuilder operating under the "Zero Home" (ゼロホーム) brand and serving as a wholly-owned subsidiary of Keihan Holdings Co., Ltd. since July 2017. The company designs, constructs, and sells custom-built wooden detached houses, real estate (land and brokerage), and non-residential wooden buildings, with a core technical platform built around the proprietary "Zero Construction Method" (ゼロ構法) certified in 2000 for narrow urban plots typical of Kyoto's historic districts. Its product line spans the 100-Year Housing (100年住宅) long-term housing standard, the BASE3 high-performance housing series (including LCCM carbon-negative variants and the GX-oriented BASE3 next), and the FRAMIUM concept home, supported by a 50-year structural guarantee.

The business operates a direct-to-consumer model through seven owned model home showrooms across Kyoto, Osaka, Hyogo, and Shiga prefectures, complemented by five real estate sales offices and an industry-first VRChat-based virtual showroom launched in 2023. Revenue is generated primarily through one-time sales of new residential properties (custom and pre-built), brokerage and intermediary fees on land and existing-home transactions, construction contracting, and condominium sales; pricing is quote-based and not publicly disclosed. The customer base consists of individual homebuyers and families in the Kansai metropolitan area seeking durable, energy-efficient, and earthquake-resistant housing, with the company emphasizing transparency through its Open Disclosure Policy (公開ポリシー) since 2002 and sustainability through the Seedling Return Project (苗木を還そうプロジェクト), which links reforestation donations in Miyazaki Prefecture to the number of structural pillars used in delivered homes.
