What COOLHEAD Japan does
COOLHEAD Japan (株式会社クールヘッド) is a privately held, founder-controlled home healthcare and welfare services provider operating exclusively in Suginami Ward, Tokyo under the "Warm Heart" (ウォームハート) brand. Founded on January 14, 2003 by Representative Director Toshio Toshima (戸島 壽男) and reorganized into a stock company in 2006, the company delivers an integrated suite of in-home services — visiting nursing, visiting care, periodic/on-demand combined care and nursing, home care planning/case management, and disability welfare services — supplemented by private-pay offerings outside Japan's public insurance scope. Customers are individual elderly, disabled, and seriously ill residents of Suginami Ward who access services through nationally standardized nursing care insurance, national health insurance, or disability welfare reimbursement schedules, with private-pay rates ranging from ¥1,200 to ¥18,000 per visit depending on discipline and duration.
The company's underlying technology stack is effectively non-existent from a software perspective: there is no proprietary platform, no mobile app, no public API, and no AI/ML components disclosed. The core "technology" is the multidisciplinary clinical workforce — visiting nurses, certified care workers, PT/OT/ST rehabilitation therapists, and care managers — coordinated through individualized care plans. The company operates from two confirmed physical sites within Suginami Ward: the headquarters at Miyabi Building 103, 2-5-1 Nishiogikita, and the visiting nurse station at 3-17-24 Kami-Igusa.
Revenue is generated almost entirely through fee-for-service reimbursement from Japan's public nursing care insurance, national health insurance, and disability welfare systems, with a supplementary private-pay stream for services beyond public coverage. Marketing and customer acquisition are predominantly community-driven — word-of-mouth, local reputation, Google Maps discovery, and social media presence (Instagram, X, Facebook, Note) — with the website serving as both service inquiry portal and recruitment channel. Active hiring across all clinical roles and the addition of the visiting nurse station in 2020 indicate ongoing incremental expansion, though geographic scope remains a single Tokyo ward.
