About SDP Japan

SDP Japan, Inc. is a healthcare services company founded in January 2014 by CEO Kazuhiko Nagayo. The firm operates as a platform business, providing comprehensive management and operational support to specialty surgical institutions, particularly in the fields of orthopedics and cardiovascular care. This model addresses systemic challenges in Japan's healthcare sector, where surgeons often lack adequate infrastructure and patients face difficulties in finding specialists. SDP Japan's business model involves developing surgery-focused clinics and handling non-medical operations on their behalf. This allows physicians to concentrate on clinical practice by outsourcing administrative functions.

The company's services for its partner medical institutions include patient acquisition marketing, procurement of supplies like medical equipment and implants, sourcing real estate, and providing administrative support. By centralizing purchasing, it achieves cost reductions on medical materials. SDP Japan aims to establish a Japanese-style Ambulatory Surgical Center (ASC) platform adapted to the country's public insurance system. This strategy is designed to meet the growing demand for surgical procedures, which are increasing by 5-8% annually in its focus areas, driven by Japan's aging population.

Since its inception, SDP Japan has supported the creation of seven surgical institutions in the Tokyo metropolitan area, which collectively performed over 3,000 surgeries in 2024, reaching a cumulative total of approximately 14,000. In June 2025, the company announced a Series D funding round of approximately JPY 4.5 billion (USD 31 million) to fuel its nationwide expansion and roll out its model to underserved regional cities.
