Keiyu Hospital

What Keiyu Hospital does

Keiyu Hospital is a private general hospital founded in 1934 and headquartered in the Minatomirai district of Yokohama, Japan. It operates 35+ clinical departments and specialty centers — including a Breast Center, Endoscopy Center, and Retina-Vitreous Center — staffed by roughly 120 full-time physicians and 354 full-time nurses within a 501–1,000 employee organization. It is designated a Regional Medical Support Hospital and serves as the sole private general hospital in its catchment area, anchored by a referral network of 600+ clinics.

The hospital's core offering is acute inpatient and outpatient care, with a heavy emphasis on advanced surgical and cancer services. Capital equipment includes a da Vinci Xi robotic surgery platform (upgraded March 2025), TrueBeam radiotherapy, 320-row CT, 3T MRI, and a Fiber Dust Thulium Fiber Laser (June 2025), supporting 11,300+ annual surgical cases. Clinical coverage is augmented through academic partnerships with Keio University, St. Marianna University, and Fujita Health University for subspecialty services including cardiac vascular surgery and plastic surgery.

Revenue is generated primarily through Japan's NHI fee schedule for inpatient and outpatient services, supplemented by self-pay offerings such as second opinions, genetic counseling, and advanced screening/diagnostics. Patient flow is driven by the regional referral network and direct community access rather than a single dominant payer or customer. Recent operational moves include digital intake via a LINE-based pre-admission tool (Poketsapo, March 2026) and rationalization of underperforming outpatient capacity (pediatric after-hours clinic discontinuation, January 2025).
