Broad incumbents

• Seirei Social Welfare Community (聖隷福祉事業団): Large social welfare organization operating hospitals, special nursing homes, and home care services primarily in Shizuoka and broader Japan. Comparable in multi-service long-term care model and non-profit structure, with similar public funding reliance.
• Benesse Style Care (ベネッセスタイルケア): Major for-profit operator of paid nursing homes, group homes, and elderly residences in Japan. Comparable in residential elderly care model, though focused on higher-acuity paid (有料) segment vs. Kouseikai's public insurance-based special nursing homes.
• Tsukui (株式会社ツクイ): Listed Japanese operator of day services (通所介護), in-home care, and group homes across Japan with hundreds of locations. Directly comparable in day service and home visit care offerings to Kouseikai's community-based services.
