What cocolonet does

cocolonet (こころネット株式会社) is a privately held Japanese holding company headquartered in Fukushima Prefecture that operates a vertically integrated portfolio of life-event services anchored by funeral operations. Through its core subsidiary Tamanoya (株式会社たまのや, founded 1892), the group runs 37+ company-owned funeral halls under the こころ斎苑 (community halls) and とわのいえ (private family-only halls) sub-brands across Fukushima, Ibaraki, Tochigi, and Yamanashi prefectures, assisted over 5,000 funerals annually, and employs 232 regular and contract staff plus officers as of January 2026. The group is staffed by more than 100 Ministry of Health, Labour and Welfare certified Level 1 funeral directors and operates 24/7/365 emergency response lines.

The company monetizes through one-time service fees on six standardized funeral plans ranging from a 130,000 yen cremation-only plan to a 526,000 yen full traditional funeral (pre-tax), plus customizable orders, corporate/joint funerals, weddings at venues such as KIOKUNOMORI and KAI KORIYAMA, and cross-sold memorial goods through 石のカンノ (tombstones), ぶつだんプラザ (Buddhist altars), and floral delivery. A recurring revenue layer is provided by Heartline mutual aid prepaid monthly plans (1,000-6,000 yen/month), the Anshin Club membership program (10,000 yen joining fee, 5-10% service discounts), and Memolead Life funeral insurance offering 300,000-3,000,000 yen in no-medical-exam death benefits. After-sales support covers Buddhist altars, grave management, inheritance procedures, and estate liquidation.

Distribution is primarily direct-to-consumer via field sales, a 24/7 phone hotline, and walk-in venue consultations, supplemented by SEO, social media, end-of-life seminars, and referrals from mutual aid members. The group was formerly listed on the TSE Standard Market (ticker 6060) but was delisted on January 29, 2026 following its absorption as a wholly-owned subsidiary of Sust Holdings (燦ホールディングス, TSE Prime: 9628), with subsequent subsidiary mergers and executive personnel changes continuing through mid-2026. No proprietary technology platform or AI/ML capability is disclosed.

Direct peers

• 燦ホールディングス (Sust Holdings): Parent company of cocolonet and one of Japan's largest funeral and ceremonial services groups, listed on TSE Prime (9628). Operates an overlapping portfolio of funeral halls, wedding venues, and mutual aid services across multiple regions, making it the closest comparable to cocolonet's business model and geographic strategy.
• 株式会社ティア (Tear Corporation): TSE-listed (2485) funeral services chain primarily operating family funeral halls in the Tokai/Aichi region. Closely comparable to cocolonet in business model (company-owned funeral halls, standardized service tiers, family-focused offerings) and target customer base.
• 公益社 (Koeisha): Large private funeral services group headquartered in Osaka with a nationwide funeral hall network and ceremonial services. Comparable to cocolonet in providing comprehensive funeral, cemetery-related, and life-event services through owned facilities.

Regional players

Emerging players
