What Hoshiiryo-Sanki does

Hoshiiryo-Sanki (株式会社星医療酸器), founded in 1960 as Hoshi Propan and rebranded in 1974, is a publicly listed Japanese medical gas manufacturer and home healthcare provider headquartered in Tokyo (ticker 5985, Tokyo Stock Exchange Standard Market). The company produces medical gases including Japanese Pharmacopoeia oxygen, nitrogen, liquid nitrogen, carbon dioxide, nitrous oxide (Anesta), and sterilization gases at three in-house filling facilities (Adachi 1987, Omiya 1994, Ayase 1995), and supplies them to hospitals, clinics, and medical facilities across Japan via a 24/7, 365-day delivery network operating out of 33 domestic sales offices. It also designs, constructs, and maintains medical gas supply infrastructure for hospitals.

Beyond gas manufacturing, the company operates a home healthcare segment that rents and sells home oxygen concentrators (Dr Oxygen 7L II, WESTELLA-5T), CPAP/NPPV devices, pulse oximeters, and the proprietary Pallet's-R tablet-based remote monitoring system with Bluetooth and GPS emergency location functionality. Additional business lines include welfare and nursing care equipment (wheelchairs, beds, mattresses), a paid nursing home (Life Stage Asagaya, 2005), day care services, visiting nursing, home care support, YaDoc telemedicine consultations, and a beauty/wellness carbon dioxide product line for esthetic and veterinary use.

Revenue is generated through a mix of one-time medical gas sales, recurring home medical equipment rentals and subscription-style remote monitoring services, professional services for gas equipment design, construction and maintenance, and fee-based nursing care services. Go-to-market is exclusively enterprise field sales targeting hospitals, clinics, and home patients, supported by participation in respiratory care academic conferences. The customer base spans 10,000+ users across institutional and home care segments, and the company holds two wholly-owned subsidiaries (Hoshi Engineering was merged in 2015; Life Stage Asagaya continues as a nursing home subsidiary).
