日本発条健康保険組合

What 日本発条健康保険組合 does

日本発条健康保険組合 (Nippatsu Health Insurance Union) is a statutory, single-employer health insurance union (健康保険組合 / kenpo) established on April 1, 1959 under Japan's Health Insurance Act. It provides mandatory health insurance coverage exclusively to the employees of 日本発条株式会社 (Nippon Hatsujo Co., Ltd., commonly known as NHK Spring) and its affiliated group companies, plus their dependents. As of March 31, 2026 the union covers 10,641 insured members (average age 43.28) and 8,832 dependents (dependency ratio 0.83), giving a total covered population of roughly 19,473 lives. Operations are administered from a single office in Yokohama (Kanazawa-ku, Fukumura 3-10) embedded in the Nippatsu Group industrial complex.

The union delivers statutory medical benefits, cash sickness/maternity benefits, and an extensive preventive-care portfolio. Core offerings include human-dock screenings, family and dependent health exams, cancer and dental screening subsidies, metabolic-syndrome guidance (特定健診・特定保健指導), a fully-subsidized 卒煙サポートプログラム (Smoking Cessation Support Program, ¥59,400/participant), the Kencom walking-activity app, sports-club and accommodation discount partnerships, and a children's health-education booklet developed with Tokyo University. The technology stack is modest but modern for a Japanese kenpo: a third-party healthcare engagement app (Kencom, operated by DeSC Healthcare Co., Ltd. since 2020), a Data Health Plan analytics system that analyzes claims and checkup data to design targeted programs, and online qualification verification integrated with Japan's national My Number Insurance Card (マイナ保険証). All qualifying members were transitioned to My Number-based eligibility verification by December 2025, with traditional health insurance certificates becoming unusable at medical institutions.

The union operates as a non-profit mutual entity funded entirely by statutory insurance premiums collected from member employers and employees via payroll deduction. There are no shareholders, no parent company, and no external equity backing. Revenue mechanics are entirely formulaic: the 2026 combined premium rate is 105.5 per 1,000 of standard monthly remuneration (general 86.2, child-rearing support 2.3, nursing care 17.0), applied to an average standard monthly remuneration of ¥434,417. GTM is fully captive — enrollment is automatic upon employment with Nippatsu Group companies through HR channels, supplemented by a quarterly newsletter (けんぽだより), an official Japanese-language website, and the Kencom app for member engagement. Participation in a 24-union consortium for joint children's health education (Kenpo Diary Kids, 2026) and a 2026 spring walking event indicate modest collaborative ecosystem activity, but no geographic or vertical expansion is pursued outside the Nippatsu Group charter.

Scale indicators4 records

Expansion highlights4 records

Direct peers

• National Federation of Health Insurance Unions (Kenporen / 健康保険組合連合会): The national federation representing all 1,400+ Japanese corporate health insurance unions including this entity. Provides pooled high-cost medical expense arrangements, advocacy, and shared services; the subject union is an active member and operational participant.
• Japan Health Insurance Association (Kyokai Kenpo / 全国健康保険協会): The public, government-administered statutory health insurance provider for SMEs and employees not covered by corporate kenpo. Operates under the same Health Insurance Act framework with comparable contribution structure and benefit mandate, making it the closest functional analogue at much larger scale (~40M insured).
• Sompo Health Insurance: Private health insurance arm of Sompo Japan that provides employer-sponsored group health products in the commercial market. Overlaps with this union in serving Japanese employer health benefit needs, though as a for-profit carrier rather than a mutual.

Emerging players

• DeSC Healthcare Co., Ltd. Operates the Kencom health engagement platform that the subject union licenses for member walking events and health missions. A technology partner with deep operational overlap on the health-promotion layer rather than an insurance competitor.

Broad incumbents

• AIG Japan Holdings: Subsidiary of global insurer AIG offering group accident, health, and travel insurance products to Japanese corporate clients. Comparable employer-benefit focus but operates as a foreign-affiliated multinational rather than a domestic mutual.
• Tokio Marine & Nichido Life Insurance: One of Japan's largest insurance groups offering group medical, accident, and disability products to corporate clients. Operates broadly across P&C and life insurance rather than specializing in the single-employer health union niche.
• Dai-ichi Life Insurance: Major Japanese life insurer offering group health, medical, and welfare products to employers. Comparable in serving Japanese workforce benefit needs but across life, annuity, and health lines rather than as a dedicated health union.
• Mitsui Sumitomo Insurance: Major Japanese non-life insurer offering group accident, health, and corporate welfare coverage. Comparable to the union in providing employer-sold benefits to Japanese workforces, though across a broader casualty portfolio.
