Two regional banks in central Japan, Aichi Financial Group Inc and San ju San Financial Group Inc, decided to integrate their operations in May 2026, creating a merged entity with total assets surpassing ¥11.6 trillion (about US$74 billion) [1, 2]. The boards reached the agreement on May 13, followed by media reports on May 14 detailing the merger and its scale [1, 2].
Shares of both banks rose after the announcement, with San ju San shares climbing between 6.8% and 8.3%, and Aichi shares rising 2.6% to 6.2% [1, 2]. This merger occurs amid a wave of regional bank consolidations in Japan. Rising interest rates and a shrinking population are increasing pressures on local banks to strengthen their competitiveness through consolidation [1, 2].
In March 2026, Bank of Nagoya Ltd and Shizuoka Financial Group Inc agreed to consolidate under a holding company, illustrating the recent trend among regional banks to combine resources [1].
Japanese hedge fund Ariake Capital Inc has taken a stake of more than 10% in Aichi Financial Group. The fund may propose measures to influence the company’s strategy as the merger progresses [1].
The new regional banking group is expected to enhance financial services and operational efficiency in central Japan. The banks will continue working toward finalizing the integration details over the coming months.
