Yamauchi

What Yamauchi does

Yamauchi Co., Ltd. (株式会社ヤマウチ) is a privately-held Japanese multi-service conglomerate headquartered in Takamatsu, Kagawa Prefecture, and operating as a wholly-owned subsidiary of Okamoto Group since 2011. Founded in 1932 as a coal merchant, the company pivoted to petroleum distribution after World War II and built a regional energy business before joining Okamoto Group, which catalyzed its transformation into a diversified lifestyle-services platform spanning nine business segments: energy (Yamauchi Self self-service gas stations, Hakko Oil wholesale), automotive maintenance (Ratchet Monkey inspection and repair shops), sports and fitness (JOYFIT, JOYFIT24, JOYFIT YOGA, FIT365, minefit, Setouchi Swimming School, 108.Tokyo, MOSH PIT, WellBe), nursing care (Joy Reha, Joy Reha SPA, Tanpopo no Watage, Medical Seed, Sasuke, Yui), beauty (Scalp Quick, JuJu), food service (Bikkuri Donkey hamburger restaurants), ceremony (Elena funeral homes), reuse (PC819.com, ReBoot), and designated management of public facilities (HAPPY BASE, Yonettsu Kochi).

The company operates through directly-owned retail and service locations (450+ as of FY2025) supplemented by franchise arrangements (Bikkuri Donkey, JOYFIT franchisees) and an active M&A pipeline that has absorbed more than twenty businesses since 2019, ranging from single-location tire shops to multi-facility senior housing operators. Its proprietary technology assets are limited and operational in nature — most notably the internally-developed 'totoco' cloud-based vehicle inspection reservation and management platform (launched November 2024, awarded the DX Award at the 4th Maintenance Business Awards 2025), the JOYFIT mobile app with charity point integration, and environmental systems (LED conversions, gasoline vapor recovery). Revenue is generated through a mix of pay-as-you-go transactions (fuel, food, ceremony, reuse), recurring monthly subscriptions (fitness memberships at ¥2,980 for FIT365 to ¥6,890 for JOYFIT24, elder care day fees), and managed-service contracts with municipal governments. Customer base is fragmented across regional Japanese households and individual consumers, with no material enterprise or B2B concentration.

Growth strategy is explicitly M&A-led and supported by Okamoto Group's ¥190.5 billion revenue scale and 800-store national footprint. The company has stated a target of 700 stores and ¥70 billion in revenue by FY2028 (versus ¥47.9 billion in FY2025) and ¥100 billion by FY2033 under the MOVE TO HAPPY corporate philosophy, with current expansion concentrated in the Kanto, Kansai, and Kyushu regions beyond the original Shikoku base.
