What Win International does

Win International is a Tokyo-based medical device trading company founded in 1983, operating as the core distribution subsidiary of the publicly listed Win Partners Group (ウイン・パートナーズ). The company has spent over four decades building a specialized presence in minimally invasive cardiovascular medicine in Japan, distributing PTCA balloon catheters, drug-eluting stents, pacemakers, implantable cardioverter-defibrillators (ICDs), CRT-D devices, ablation catheters, stent grafts, TAVI valves, and peripheral vascular and neurosurgical devices, alongside diabetes management equipment including insulin pumps and continuous glucose monitoring systems. Beyond device distribution, the company provides medical facility design and construction services (operating room design, large equipment packages), consulting services for hospital operations, and a proprietary lot-management system branded SHINZO (信蔵君).

In April 2026, the company launched WIN Asset, a cloud-based medical device and asset management SaaS developed by clinical engineers (CEs) that extends beyond medical equipment to encompass administrative and welfare assets (PCs, electric beds). The platform features PMDA automatic data acquisition, offline inspection mode, department-level access control, a multi-hospital dashboard, and 24/7 AI chatbot support. Distribution is exclusively domestic through a direct sales-led, proposal-based go-to-market motion delivered via ~20 regional sales offices spanning all eight of Japan's macro-regions. Pricing for medical devices follows standard distributor one-time purchase economics, while WIN Asset is sold on annual subscription terms with quote-based pricing. The customer base is exclusively Japanese hospitals and medical institutions.
