Osaka Gas Housing Equipment

What Osaka Gas Housing Equipment does

Osaka Gas Housing Equipment Corporation (大阪ガス住宅設備株式会社) is a private Japanese housing corporation and a subsidiary of the Daigas Group (formerly the Osaka Gas Group), headquartered at 4-1-2 Hiranomachi, Chuo-ku, Osaka. Founded on July 22, 1978, with capital of ¥100 million, the company historically built and sold detached residential houses under the 大阪ガス住設の家 (Osaka Gas Housing Equipment Homes) brand, primarily in the Kansai Region of Japan. Its product line historically included proprietary housing designs and the jet stream bath (ジェット噴流バス), the latter marketed through group affiliate Osaka Gas Marketing Co., Ltd. The company is led by President and Representative Director Ueno Yasushi (上野 泰司).

The company's core business has undergone a fundamental pivot: in a public notice on its corporate website, Osaka Gas Housing Equipment announced the termination of new orders for detached houses (戸建住宅の新規受注を終了) effective from April 2025 (Reiwa 7), citing various circumstances. Going forward, the company will not take on new home construction projects. Instead, its operational scope is narrowed to after-sales service and warranty support for the legacy installed base of homeowners who previously built or purchased homes through the company. Maintenance operations are formally outsourced to Daiwa House Reform Co., Ltd. under the company's responsibility, with customer inquiries routed through two dedicated toll-free call centers (0120-554-340 and 0120-000-555) and a partner-managed jet bath hotline (0120-135-498).

The after-sales service infrastructure includes an Owner Support Site (owners.ogj.co.jp) providing self-service maintenance guidance covering water systems, interior fittings, flooring, walls, ventilation, exterior fixtures, and gas equipment, plus submission of maintenance requests that flow to Daiwa House Reform. The company shares customer information jointly with parent Osaka Gas Co., Ltd. and group affiliate Osaka Gas Marketing Co., Ltd. for gas-equipment safety, warranty repairs, and energy services. Component-level relationships exist with YKK AP (exterior fixtures), EIDAI (interior sliding doors), and ventilation-filter suppliers (Kyowa Nasta, Sarashina Manufacturing, Unix). Revenue, pricing, and headcount are not publicly disclosed.
