Cross-base strategy

  • A wide-area expansion not found in other Shikoku regional banks: Shikoku (Tokushima + Kagawa) + Osaka (former Taisho Bank branch network)
  • The Awa-odori economy (Tokushima) + the udon economy (Kagawa) + access to the Kansai economic zone (the Taisho Bank lineage in Osaka)
  • Tourism finance for the Shikoku 88-sacred-site pilgrimage + manufacturing finance for Seto Inland shipbuilding · Shikoku paper
  • Agricultural finance (local farm products such as mandarin oranges · udon flour · sweet potatoes)

Alliance / acquisition strategy

  • Tokushima + Kagawa management integration (2010-04-01): an equal-merger-type HD-ification of adjacent Shikoku 2 -prefecture regional banks (similar cases: Yamaguchi FG · Nishi-Nippon FH, etc.)
  • Taisho Bank rescue subsidiary-ization (2017): strategic M&A to acquire the Osaka base, absorbing the financially distressed Taisho Bank
  • Tokushima Taisho Bank merger (2020-01): going from 2 行 → 1 行 structure within the HD to cut duplicate costs · integrating the Osaka + Tokushima branch networks

Survival strategy in a depopulating region

  • The Shikoku 4 prefectures have a high depopulation rate even within Japan → complemented by access to the Kansai economic zone (the Taisho Bank lineage)
  • The intermediate niche between megabanks and shinkin (local-SME main bank)
  • Specialized in local-industry finance for tourism · agriculture · manufacturing

Position in the regional-bank-consolidation context

4. Regulation / policy

  • Supervisor: FSA + Shikoku Local Finance Bureau
  • Holding-company regulation: Banking Act Article 52 -17
  • Recent policy points:
    • 2024~ BOJ policy-rate normalization → bonus from improved domestic deposit-loan margins
    • 2025~ regional-bank consolidation pressure (the FSA’s regional-bank-integration inducement measures)
