Isahaya Memorial Hospital

What Isahaya Memorial Hospital does

Isahaya Memorial Hospital (諫早記念病院) is a 112-bed care-mix community hospital in Isahaya City, Nagasaki Prefecture, Japan, operated by the private medical corporation Kohzenkai (医療法人 宏善会). Founded in 1953 as Takahashi Surgery Clinic and renamed to its present identity in 1999, the hospital operates 34 general acute beds, 73 community-based integrated care beds, and 5 convalescent beds, employing 281 staff across 12+ clinical departments. Its clinical mix is anchored by orthopedics (with a next-generation CT-based surgical navigation system supporting ~280 hip and knee replacement cases per year and ~500 orthopedic/plastic surgical procedures in fiscal year 2024), cardiology and cardiovascular internal medicine, diabetes and metabolic medicine, respiratory medicine, neurology, gastroenterology, urology, general internal medicine, plastic surgery, and a newly added hypertension outpatient clinic, plus an elective anti-aging IV therapy clinic. The facility is equipped with a 64-row CT, 1.5T MRI, cardiovascular catheterization lab, endoscopy, spirometry, FeNO analysis, and polysomnography. Supporting the hospital, Kohzenkai operates three wholly-owned adjacent subsidiaries: the Isahaya Memorial Hospital Visiting Nursing Station, the Himawari Care Management Office, and Himawari Day Care Service, delivering home-visit nursing, day rehabilitation, day care, and care-management services within a roughly 30-minute radius of Isahaya City.

Revenue is generated primarily through Japan's public health insurance system via outpatient and inpatient fees (specialty consultations, diagnostic examinations, surgical procedures, hospitalization at ¥2,750–¥5,500/day for room upgrades), fee-for-service health examinations (¥32,000–¥55,000 per checkup course with optional CT/MRI add-ons), nursing-care insurance reimbursement for day and home-care services, and elective self-pay IV therapy. Customer acquisition is sales-led and relationship-driven: direct walk-ins, referrals through a dedicated Medical Coordination Office, and inbound transfers from regional partners including Isahaya General Hospital, Japanese Red Cross Isahaya Hospital, Miyazaki Hospital, and Nagasaki Medical Center. The hospital also operates a dedicated recruitment pipeline (kohzenkai.or.jp/recruit/) and a functional-enhancement surcharge program positioning it as a community "family doctor" hub. Recent operating changes include Saturday outpatient closure from January 2026 (physician work-style reform), ward reorganization in August 2025, and incremental product launches through 2026.
