TL;DR
A second-tier regional bank based in Chiba Prefecture (TSE PRIME 8337, nickname “Chiba Kogin”). 1952-01-18 Founded as the former Chiba Shoko Credit Cooperative, it went through conversion to a shinkin bank → conversion to an ordinary bank → its current name in 1973 . A standalone bank that has not adopted a holding company, it holds the No.2 position within Chiba Prefecture (No.1 is chiba-bank). Triggered by management deterioration around 1991 , it was rehabilitated as a de facto Mizuho-affiliated second-tier regional bank by accepting strategic shareholders from the former Dai-Ichi Kangyo / Fuji Bank lineage (now mizuho-fg). It specializes in SME lending and community-based sales, and in the wholesale domain it leverages referrals / synergies with mizuho-fg. •

4. Regulation / policy
- Supervisor: Financial Services Agency (FSA)
- Business type: Second-tier regional bank (member of the Second Association of Regional Banks)
- Recent policy issues:
- 2024~ BOJ policy-rate normalization → bonus to regional-bank interest margins (second-tier regional banks benefit too)
- 2024~ regional-bank consolidation pressure (the FSA’s consolidation-promotion policy) — whether Chiba Kogyo can continue its standalone path
- The management impact of demographics within Chiba Prefecture (aging, movement to urban areas)

[!info] Verification status confidence: likely (based on v1.0 public information 2026-05-19, 2026-05-29 figures cross-checked). Total assets, deposits, loans, employees, head-office location, subsidiaries, and major-shareholder ratios are confirmed via the 2025年3月-term financial summary / mini-disclosure magazine / official timely disclosure. Important update: the old draft’s positioning as “a standalone bank under a Mizuho-affiliated strategic shareholder” differs from the current state — chiba-bank became the largest shareholder in 2025-03-28 (19.00%; Mizuho is 15.25%), and per the 2025-09-29 basic agreement / 2026-03-25 final agreement it will establish the joint holding company “Chiba Financial Group” with chiba-bank in 2027-04 . The trigger for the management deterioration and entry into the Mizuho group was the 2000 Fuji Bank investment and public-funds injection (the old draft’s “around 1991 “ was inaccurate and is corrected).
