The Hokkaido Bank has 134 domestic branches, with 131 of them in Hokkaidō, and one each in the Tohoku region, Tokyo, and Osaka.

The Hokkaido Bank was established on March 5, 1951 in Sapporo.

However, these talks broke off and Hokkaido Takushoku Bank subsequently entered bankruptcy.

Approximately one year later on May 23, 2003, the banks agreed to merge management.

On September 1, 2004, both banks became subsidiaries of the Hokuhoku Financial Group.
