The story
The Kanto Tsukuba Bank can trace its roots to the establishment of the Shimotsuma Mutual Aid Credit Company (Shimotsuma Mujin Kaisha) in 1927, which would later become the Tsukuba Bank. The Kanto Bank was established in Tsuchiura City in 1952. These two banks merged in 2003, forming the current bank.
In November 2004, the Kanto Tsukuba Bank and the Ibaraki Bank announced plans for a merger, to take place in 2006, that would have created the Hitachino Bank. The bank was scheduled to begin operations in July 2006, but disagreements between the two banks resulted in the deal being dropped. The new bank was expected to have total assets of around two trillion yen, making it the dominant regional bank in the prefecture.
