This entry sits under regional-banks INDEX. Read it against Fukuoka FG (FFG) for peer / contrast context and banking index for the broader system / regulatory boundary.

TL;DR

A regional bank FG rooted in Mie Prefecture. Established through the 2018-04-02 management integration of Mie Bank + Daisan Bank, with 2021-05-01 merger of the two banks → birth of San ju San Bank. The name “San ju San” (Thirty-three) is a double meaning taking the “san” (three) from both banks — “san (mie / Mie) + san (third / Daisan)” (English name: San ju San = 33). Located on the Kansai-leaning boundary of the Chukyo economic zone, competing with the in-prefecture No.1 hyakugo-bank (Hyakugo Bank).

  • Mie Prefecture base: a unique position located on the Kansai-leaning boundary of the Chukyo economic zone
  • Dual nature: economic-zone spillover from the Nagoya area (Chukyo) + cultural proximity to the Kansai region

Industrial base

  • Tourism: Ise Grand Shrine (annual pilgrims ~1000 万 people) + Toba・Shima resorts
  • Fisheries: local industries such as Ise lobster・pearl cultivation
  • Industry: Yokkaichi industrial complex (petrochemicals・electronic components)

  • Holding-company regulation: Banking Act Article 52 -17
  • Recent policy issues:
    • 2024~ BoJ policy-rate normalization → regional-bank earnings-margin improvement bonus
    • regional-bank reorganization pressure under regional revitalization・population decline
    • strategic choice of the boundary position between the Chukyo zone vs the Kansai region

7. Open questions

  • What is the speed of lending expansion into the Nagoya area (Aichi Prefecture)?
  • The direction of competition・cooperation with the Chukyo zone (juroku-fg / Ogaki Kyoritsu, etc.)?
  • What is the digital strategy in the next medium-term plan (from 2024 onward)?
  • The possibility of wide-area cooperation with Kansai-region regional banks?
  • hyakugo-bank (Hyakugo Bank, in-prefecture No.1 competitor in Mie)
  • juroku-fg (Juroku FG, Chukyo-zone adjacent competitor)
  • mufg (Chukyo-based megabank of the former Tokai Bank lineage)
