Aomori Michinoku Bank, Akita Bank, and Bank of Iwate have entered discussions to pursue a management integration, with a target completion date of April 2028. The banks intend to establish a common holding company rather than a direct merger, a structure that would allow each institution to maintain its original name and legal entity.

The proposed integration aims to establish a headquarters in Morioka City. While there are currently no plans to integrate IT systems, the banks have stated that services for customers and business partners will remain unchanged for the time being.

The move is motivated by a tightening business environment resulting from rising interest rates and a shrinking population. The banks have expressed a “sense of crisis” regarding rapid population decline in the North Tohoku region, specifically within Akita, Aomori, and Iwate prefectures. By coordinating management through a group structure, the institutions seek to achieve synergies in regional production, capital, profitability, and management stability.

If successful, the combined group is expected to hold approximately 13.3 trillion yen in consolidated assets. This would make the entity the largest regional banking group in the Tohoku region, surpassing the Sendai-based 77 Bank, and the tenth largest regional banking group in Japan.
