Seiwakai

What Seiwakai does

Seiwakai is a private Japanese medical corporation (医療法人 清和会) headquartered in Yanagawa City, Fukuoka Prefecture, operating Nagata Hospital, a 182-bed care-mix (ケアミックス) facility that delivers acute, chronic, rehabilitation, and palliative care to the regional population. Its 14 clinical departments span internal medicine subspecialties (respiratory, gastroenterology, cardiology, diabetes, hepatology, allergy, dialysis, sleep disorders, geriatrics), rehabilitation, palliative care, and radiology, supported by three dedicated specialized centers: the Health Support Center, the Clinical Trial Center, and the Dialysis Center. The organization's broader service footprint encompasses 18 affiliated facilities including a satellite clinic (Mitsuhashi-Nagata Clinic), a geriatric care facility (Shanti), a dementia group home (Tsukuda), a visiting nursing station (Hanamizuki), helper services, day care, residential elderly homes, and community care plan services, collectively creating a vertically integrated care network spanning hospital, convalescent, and home/community settings.

The technological core combines an electronic medical record (EMR) system with DPC (Diagnosis Procedure Combination) data infrastructure and an anonymized medical data framework for third-party sharing. Recent capital equipment investments include the PHILIPS Azurion7 M20 vascular angiography system (installed July 2024) with cone-beam CT and automated dose reduction, Paramount Bed's Nemuri SCAN non-wearable under-mattress sleep monitoring sensor (introduced March 2025), and an AI-powered gait analysis tool branded Torto (introduced June 2025) deployed across the hospital rehabilitation department and the Shanti geriatric facility. The hospital maintains certified clinical technology infrastructure, including Japan Council for Quality Health Care certification, ISO certification, and designation as a Japanese Society of Gastroenterology colorectal disease specialty facility, and participates in national clinical research including Consumer Affairs Agency-mandated food allergy monitoring surveys and the recurring ELNEC-J palliative care nurse education program (13 editions).

Revenue is generated primarily through reimbursements under Japan's national health insurance fee schedule for covered inpatient, outpatient, surgical, rehabilitation, dialysis, palliative, and clinical trial services, supplemented by out-of-pocket payments for non-covered items (notably vaccinations priced individually per dose and optional overnight health checkup packages such as the Ohana Dock). Self-pay channels include the hospital-based Health Support Center, a foot care outpatient clinic (launched July 2024), and the Mitsuhashi-Nagata Clinic's intranasal influenza vaccine service (Flumist, launched October 2025). Patient acquisition is relationship-driven rather than marketing-led, depending on community reputation, physician referrals managed through the formal Regional Coordination Office (地域連携室), corporate and municipal health-screening contracts, and recurring community engagement (diabetes education classes, COPD awareness events, concerts, and the quarterly Clover Newsletter distributed at the hospital and Nishitetsu Yanagawa Station).

3. Health Examination and Screening Services: The hospital operates a Health Support Center (健康サポートセンター) offering comprehensive health examinations, lifestyle disease screening, and overnight stay health checkup programs (御花ドック).
