What POSSIBLE Japan does

POSSIBLE Japan (ポシブル医科学株式会社) is a Japanese long-term care and rehabilitation services provider founded in February 1999 in Nara Prefecture, now headquartered in Higashiosaka, Osaka. The company operates four core day service (通所介護) formats — a full-day rehabilitation type using Finnish HUR air-pressure machines and Redcord suspension training with bathing and meals; a half-day rehabilitation type without meals; the Kentoshi Rehabilitation Center composite-functional-improvement type located in the Kita-Osaka medical cluster combining exercise, oral function, nutrition, and tablet-based dual-task cognitive training; and the Life Garden full-day recreation-oriented type — alongside home-visit nursing (24/7), home-visit care, care plan creation, and welfare equipment rental/sales with home modification services. Its proprietary methodology rests on 20-plus years of accumulated rehabilitation protocols emphasizing self-efficacy (自己効力感) to drive behavioral change and prevent deterioration to higher care levels.

POSSIBLE generates revenue primarily through Japan's national long-term care insurance system (介護保険) via fee-for-service reimbursement at direct-operated facilities, supplemented by an asset-light franchise (FC) program that licenses its methodology, cloud systems (Care Supporter, Kanamic), and supervisory support to doctors, companies, and care operators across Japan. A secondary B2B revenue stream comes from corporate health management services (健康経営支援) — seminars, musculoskeletal and fall-prevention training, and wellness evaluations — sold to enterprise clients including JR West Japan, Suntory, AEON Mall, and Japan Post. The company operates 50+ locations across 13 prefectures, staffed by 414 employees (March 2025) including nurses, physical therapists, occupational therapists, speech therapists, and care managers.

POSSIBLE became part of the JR West Japan Group in January 2014, integrated JR West Japan Maintenance Tech's nursing care business into a new J Support Division in April 2019, and in July 2023 became a wholly-owned subsidiary of the Solast Group (株式会社ソラストグループ) — a healthcare, nursing care, and childcare platform. Franchise store openings accelerated post-2023, with new FC locations in Kyoto, Ashiya, Akashi, Wakayama, Matsuyama, Yodogawa, and Nishinomiya between June 2023 and June 2025, indicating ongoing asset-light geographic expansion under the new parent structure.
