Kouseikai Mizuno Hospital

What Kouseikai Mizuno Hospital does

Kouseikai Mizuno Hospital (医療法人宏生会 水野介護医療院・水野クリニック / Medical Corporation Kouseikai Mizuno Nursing Care Clinic Mizuno Clinic) is a privately held Japanese medical corporation operating a 100-bed nursing care medical facility (介護医療院) and an outpatient clinic in Seto City, Aichi Prefecture. The organization underwent a structural transition on July 1, 2023, rebranding from a traditional convalescent hospital (療養型病院) to a higher-acuity nursing care medical facility under Japan's 2018 long-term care reimbursement framework. It serves a single customer segment — elderly patients requiring ongoing post-acute medical care, nursing, and rehabilitation — through integrated inpatient, outpatient, and preventive services.

The core operating model combines long-term inpatient nursing care (covering central venous nutrition, tracheostomy management, oxygen therapy, sputum suction, and rehabilitation) with outpatient internal medicine, rehabilitation, health examinations, and vaccinations. Operationally distinctive features include an in-house pharmacy (院内処方) that lets patients fill prescriptions on-site and ward-dedicated medical clerks (メディカルクラーク) that free nurses from administrative work. The organization also operates the affiliated Sukoyaka-so (すこやか荘) elderly care facility as a wholly-owned subsidiary, building a small post-acute care ecosystem. It holds the 在宅復帰機能強化加算 (Home Return Function Reinforcement Addition) certification, originally approved February 1, 2016.

Revenue is generated almost exclusively through Japan's universal national health insurance and long-term care insurance reimbursement systems, with pricing set by the national medical fee schedule. A modest employee benefit program (Benefit Station partnership with Benefit One, June 2017) and resort accommodation discounts (Resort Trust) support staff retention rather than drive commercial revenue. The dental department was announced for closure effective March 31, 2025. The facility employs 180+ staff and serves only the local Seto City catchment area, with no evidence of expansion, M&A, or external capital backing.
