RIEI

What RIEI does

RIEI Co., Ltd. (株式会社リエイ) is a privately-held Japanese life-services group founded in 1972 (formally incorporated 1980) and headquartered in Urayasu, Chiba. The company operates four segments: (1) Life Service — outsourced management of corporate welfare facilities including employee dormitories, student housing, recreation and training centers, currently covering 537 facilities and 9 corporate serviced apartments; (2) Food Service — facility catering, corporate/school cafeterias, bento lunch delivery, and branded retail food products, operating at scale of approximately 13 million meals annually across brands such as Manyoken (ekiben), Moriyama Napoli (frozen pizza, acquired 2022), Mamoka-ru (industrial catering, acquired 2020), and Stockholm Roast (coffee, acquired 2025); (3) Elderly Care Service — private nursing homes, group homes, day care centers, and visiting care delivered under the Communicare24 brand since 2000 across 81 locations primarily in the Greater Tokyo Area, with revenue subject to Japan's Long-term Care Insurance (LTCI) fee schedule; and (4) Global Business — Japanese-style elderly care operations in China via three subsidiaries/JVs (Beijing, Shanghai with a 300-bed nursing home, Chengdu) plus consulting and caregiver training services for Asian-market entrants.

Revenue mechanics mix recurring managed-services and LTCI-regulated fees with transaction-based food sales and professional-services consulting. RIEI's go-to-market combines direct-to-consumer care operations, B2B sales through five regional sales offices (Osaka, Nagoya, Sapporo, Fukuoka, Okayama), and e-commerce/retail channels for branded food products. The group includes the founding RIEI Co., RIEI LIFE COMPANY, RIEI-FLAG (real estate leasing including Honolulu, Hawaii), RIEI FOOD LABO production facilities (Urayasu and Sapporo), and recently acquired Oval Technology Co., Ltd. (technology/systems, 2026). For the period ending March 2025, RIEI reported consolidated revenue of ¥19,702 million against a 4,390-employee group headcount, with operations spanning Japan, mainland China, and a small U.S. real estate footprint.
