What DT Kyosaikai does
DT Kyosaikai (legally 一般社団法人NTTグループ共済会 / NTT Group Mutual Aid Association) is a Japanese general incorporated association that operates an internal mutual aid platform for NTT Group employees and retirees. The organization was established in 2014 and is headquartered in Grand Park Tower, Shibaura, Minato-ku, Tokyo. It administers four core products: the NTT Group Mutual Aid Pension (共済年金), a supplemental retirement savings vehicle with cafeteria-style incentives; the NTT Group Orphan Education Fund (遺児育英基金), which provides educational grants to children of deceased NTT Group employees up to age 22; Salary Deduction Services (給与控除事業) for life and casualty insurance; and Group Insurance (団体保険) at discounted group rates. Membership is closed to NTT Group constituents: approximately 200 NTT Group companies participate as corporate (法人) members and approximately 150,000 employees and retirees participate as individual (個人) members.
Revenue is generated through recurring membership contributions, pension contributions, and group insurance premiums collected via NTT payroll salary deduction (給与控除). The go-to-market is entirely internal to the NTT Group: members access a dedicated portal gated by employee name codes (氏名コード), and administrative onboarding is facilitated through NTT Group HR and welfare departments. The association is governed by a chairman (会長) and a board of elected member representatives and corporate member representatives, with annual general meetings (定時社員総会) serving as the primary governance forum. It publishes annual financial disclosure documents (balance sheets and net asset fluctuation statements) but does not publicly disclose specific revenue figures.
The organization holds a Health Management Excellence Corporation 2026 (Next Bright 1000) certification from Japan's Ministry of Economy, Trade and Industry and the Japan Health Science Council, reflecting its workplace health management practices. It previously operated under the name 相互扶助部 (Mutual Aid Department) and has since transitioned its fire mutual aid service into a closed/ended business line. The association is not publicly traded, has no parent company, and has no disclosed external funding sources.
