Recent moves12 records

Expansion highlights4 records

Broad incumbents

• Tokushukai Medical Group (徳洲会): One of Japan's largest private hospital groups with ~70 facilities, many in rural and underserved areas. Comparable rural acute care footprint, though operating under a for-profit private model rather than cooperative.
• Japanese Red Cross Society (Medical Centers): Operates ~90 Red Cross hospitals across Japan under public medical institution status, providing acute care, emergency, and disaster medical services comparable to JA Koseiren's designated hospital functions, but at much larger national scale.
• Saiseikai (Social Welfare Organization): Long-established social welfare organization operating hospitals and care facilities across Japan under public medical institution designations. Comparable mission-driven non-profit hospital operator with similar acute and elderly care service mix.
• National Hospital Organization (NHO): Japan's largest publicly-operated hospital network of 140+ hospitals providing similar designated public medical institution services nationwide. Broader incumbent operating at national scale with overlapping public hospital designations.

Emerging players

• Kameda Medical Center (亀田総合病院): Large private general hospital group in Chiba Prefecture offering integrated acute, rehabilitation, and elderly care. Comparable in integrated care model and scale, but operates as a private for-profit rather than cooperative.

Direct peers

• JA Fukuoka Koseiren (JA福岡厚生連): Another prefectural JA Koseiren operating general hospitals, clinics, and elderly care facilities in Fukuoka Prefecture under the same cooperative union model. Highly comparable structure, scale, and service mix.
• JA Tokushima Koseiren: Tokushima prefectural agricultural cooperative welfare union running general hospitals and welfare facilities with the same JA Koseiren charter. Direct peer in scale, mission, and operating geography (rural western Japan).
• JA Hiroshima Koseiren (JA広島厚生連): Adjacent-prefecture agricultural cooperative union operating a similar multi-hospital and elderly care network under the same national JA Koseiren framework. Closest direct comparable in business model, ownership structure, service mix, and rural Japanese regional hospital footprint.

Others

• Yokohama City University Hospital: Public university hospital offering comparable designated functions (DPC, cancer treatment, emergency, disaster medical) but in an urban academic setting rather than rural cooperative context. Useful for understanding peer reimbursement economics under the same insurance system.

Regional players

• Saga University Hospital: Regional public university hospital in adjacent Saga Prefecture providing comparable designated public hospital functions in a similar rural western Japan market context. Adjacent geographic peer operating under the same national insurance framework.
