中京銀行 (Chukyo Bank, historical)

Wiki route

This entry sits under the regional-banks INDEX as the historical predecessor anchor for current operating bank Aichi Bank under Aichi FG. Read it against the The Bank of Nagoya in-prefecture rival and San Jusan Bank / The Juroku Bank Chubu peers, and against regional-bank consolidation pattern for the broader system / regulatory boundary.

TL;DR

Chukyo Bank, Ltd. (株式会社中京銀行) was a second regional bank headquartered in Nagoya City, Aichi Prefecture, that merged with the former Aichi Bank in 2025-01-01 and was consolidated into Aichi Bank (operating boundary migration complete). Established through the 1953 年 consolidation of “第三相互無尽 + 第十七相互無尽,” it was a typical “mutual-bank-origin second regional bank” that went through the path of mutual savings bank → second regional bank ordinary-bank conversion. The former securities code TSE 8530 was delisted at the time of Aichi FG’s establishment (2022-10), and this page is positioned not as the current legal entity but as a pre-merger historical anchor. ^•
