What Kokoro Net does

Kokoro Net Group (こころネット株式会社) is a regional Japanese life-event services conglomerate headquartered in Fukushima City, operating across five prefectures in the Tohoku and Kanto regions (Fukushima, Ibaraki, Tochigi, Yamagata, and Yamanashi). The group's core business is funeral services, delivered through 36 funeral halls operated by subsidiary Tamanoya under the Kokoro Saien and Towanoie brands, with 24/7 availability and minimum 30-minute response capability. Supporting businesses include Heartline's prepaid mutual aid subscription plans (F1/F2/F3 tiers at 120,000-360,000 yen over 5-10 year installments), With Wedding's two ceremony venues (KIOKUNOMORI and KAI KORIYAMA), Fleur's flower wholesale and eco-paper coffin (Yushu) operations, Kanno Trading's stone materials and gravestones, Budatan Plaza Buddhist altar retail, and Memory Lead Life funeral insurance.

The business model combines one-time transactional revenue (funerals, weddings, altar/grave sales) with recurring subscription revenue (Heartline mutual aid monthly installments, Memory Lead Life insurance premiums). Go-to-market is direct-to-consumer through physical branch offices, in-person enrollment consultations, and a Heartline Partner corporate benefit program; the company does not disclose any proprietary technology platform, and digital channels are limited to a 24/7 flower wholesale e-commerce site and corporate websites. The group was historically listed on TSE Standard Market (ticker 6060) but became a wholly-owned subsidiary of San Holdings (燦ホールディングス, TSE Prime: 9628) via share exchange effective January 29, 2026, with ongoing subsidiary mergers and capital restructuring underway.

The customer base is individual Japanese consumers and families needing funeral, wedding, and memorial services, plus a small corporate channel via the Heartline Partner employee benefit program. Pricing tiers range from 130,000 yen for basic cremation to 578,600 yen for general funerals, with mutual aid contracts structured as 1,000-6,000 yen monthly installments. Customer testimonials emphasize responsiveness and compassionate service, consistent with the trust-driven nature of the category.

Broad incumbents

• 燦ホールディングス (San Holdings): TSE Prime-listed parent company of Kokoro Net since January 2026, operating a broader national funeral and life-event services portfolio. As the acquirer, it now encompasses Kokoro Net's Tohoku/Kanto operations within a wider national platform.
• Service Corporation International: Largest funeral services company in North America operating funeral homes, cemeteries, and cremation services. Comparable as a broad incumbent in the death care services industry, though operating in a different geography and regulatory environment.

Direct peers

• 株式会社メモリード (Memorido): Fukuoka-based funeral services and mutual aid company operating funeral halls and life-event services across Japan. Comparable business model combining funeral hall operations with prepaid mutual aid plans and related life-event services.
• 株式会社極楽 (Gokuraku Group): Nagoya-based funeral services and life-event company operating funeral halls and related services in central Japan. Comparable funeral hall operator with similar service portfolio including memorial services and family ceremony offerings.
• 株式会社アルファクラブ (Alpha Club): Japanese funeral services group operating under multiple regional brands with funeral halls and mutual aid plans. Comparable integrated life-event service provider serving similar customer segments through direct-sales and physical hall network.
• ティア株式会社 (Tear Corporation): TSE-listed Japanese funeral services company operating funeral halls and mutual aid plans across multiple regions. Directly comparable to Kokoro Net's Tama no ya funeral halls and Heartline mutual aid offerings with similar GTM model and customer demographic focus.
• 株式会社公益社 (Koeisha): Osaka-based funeral services company operating a network of funeral halls and related memorial services. Comparable regional funeral services operator with similar in-person direct-sales model and customer demographic focus on elderly Japanese families.
• 株式会社くらしの友 (Kurashi no Tomo): Tokyo-based funeral services and mutual aid company with extensive hall network. Comparable full-service funeral business model including funeral halls, mutual aid prepayment plans, and related life-event services serving Japanese families.

Emerging players

• 家族葬のファミーユ (Famille): Specialized family-only funeral hall operator expanding across Japan. Comparable as a focused competitor in the family-funeral format that Kokoro Net is actively expanding through its Towanoie brand, representing a direct emerging-format threat.

Regional players

• 株式会社JAライフサポート (JA-affiliated mutual aids): Japan agricultural cooperative-affiliated mutual aid funeral service providers. Comparable as a major competitor in the prepaid funeral mutual aid segment where Heartline operates, leveraging JA's broader member base and rural geographic reach.
