TL;DR

A systemic central financial institution whose members are Japanese credit unions. According to the official company profile, the establishment date is 1954-03-29, and the number of members as of 2025-03-31 is 143 credit unions. Responsible for coordinating funds through deposit and loan transactions with credit unions, managing surplus funds, supporting business stability, providing proxy loans, and supporting over-the-counter sales of financial products. The difference between Shinkin banks and banks is determined not by an undefined “strictness” ranking, but by the underlying law, investor qualifications, and legal upper limits on deposits and loans made by non-members. ^[Sources: https://www.zenshinkumiren.jp/company/profile/; https://www.zenshinkumiren.jp/credit-union/.]

Sources: Each central organization has a different legal basis, membership definition, and base date, so they cannot be combined based on size ranking or approximate numbers. The 143 members of Zenshin Union are based on the official company profile as of 2025-03-31. ^[Sources: https://www.zenshinkumiren.jp/company/profile/; https://www.shinkin-central-bank.jp/about/profile/company.html; https://www.nochubank.or.jp/about/profile.html; https://www.rokinren.com/about/profile.html.]

Characteristics of member shinkumi

• A credit cooperative = based on the SME Cooperatives Act + the Kyokin Act, a separate legal system from the Credit Union (Shinkin) Act
• Legal limit on transactions with non-members: In the comparison table of the Federation of Credit Unions, it is explained that deposits and loans made by credit unions to non-members are limited to the total 20%. Shinkin banks also have limits on loans to non-members, so they do not simply rank them based on ``stringency’’.
• 3 classifications:
  • Regional shinkumi (the majority, serving regional members)
  • Industry shinkumi (workers in a specific industry; e.g., physicians’ shinkumi, Metropolitan Police staff shinkumi)
  • Occupational shinkumi (those belonging to a specific company/organization)
• The size of individual credit unions should be confirmed through official disclosures, and the overall range and ranking of the business types should not be determined based on rough numbers.

The 4 pillars

Credit-cooperative shared systems center

• Small and medium shinkumi cannot make large-scale IT investments on their own → Zenshinkumiren leads the joint operation of the core accounting system
• The same model as the Shinkin Central Bank’s “Shinkin Shared Center,” but the shinkumi version is smaller in scale
• Individual shinkumi can choose between their own accounting system vs joining the shared center

Credit-cooperative ATM network

• Fee-preferential ATM use mutually among member shinkumi (a model similar to shinkin ATM interconnection)
• Partnerships also with other-sector ATMs such as Seven Bank / Aeon Bank / Japan Post
• Amid the trend of megabanks / regional banks cutting their own ATMs, it survives as regional infrastructure

3. History

History of failed-shinkumi rescues

• Late 1990 年s to early 2000 年s: many shinkumi failures (Kansai Kogin, the Chogin-affiliated cooperatives, etc.)
• Coordinated with the Resolution and Collection Corporation (RCC) for failure resolution → centered on business transfers to sound shinkumi
• Zenshinkumiren is indirectly involved through industry-safety-net contributions (credit-cooperative-industry contributions)
• Failures of Chogin-affiliated shinkumi → controversy over injection of public funds (became a political issue in the 2000 年s)

Core strategy

• Maintaining the “central bank of credit cooperatives” function: surplus-fund management + liquidity supply for the shinkumi industry’s 143 cooperatives
• Providing common infrastructure for the shinkumi industry: shared systems center + ATM network
• Regional financial safety net: centrally aggregating credit and fund-management operations that shinkumi find difficult on their own

Competitors / substitute forces

• Megabanks / regional banks mounting a lending offensive toward shinkumi members (SMEs) → pressure to shrink shinkumi business
• Net banks / fintech eroding deposits and settlement for individuals
• Regional-bank reorganization also brings cooperation with shinkumi (capital participation, business partnerships)
• Core customers = small, micro, and regional members, with residual value in domains megabanks and regional banks do not pursue

Government / regulatory policy

• Supervisor: FSA + Ministry of Economy, Trade and Industry (the SME Cooperatives Act)
• Cooperative-financial-institution safety net: enrollment in the Deposit Insurance Corporation (DIC)
• Industry contribution funds: loss-reserve contributions common to the shinkumi industry
• Response to regional financial challenges: drew renewed attention in the 2020 年s “challenges of regional financial institutions” debate

5. Governance

• The general representatives’ meeting (representatives of member shinkumi) is the highest decision-making body
• The chairman = a representative of member shinkumi / former FSA or Ministry of Finance officials, etc.
• Executive appointments tend toward government involvement (the central 2 federations + Norinchukin follow the same pattern)
