Adachi Seiwa Shinkin Bank

Adachi Seiwa Shinkin Bank is a Japanese cooperative financial institution serving Tokyo's Adachi Ward and surrounding areas. As a shinkin bank, it focuses on providing financial services to small and medium-sized enterprises, local residents, and community organizations within its designated service area.

The bank was formed through the merger of two local shinkin banks in Adachi Ward, creating a larger institution better positioned to serve the community. Adachi Seiwa Shinkin Bank operates as a member-owned cooperative, emphasizing regional prosperity and mutual support among its members.

In 2024, the bank announced plans to merge with Toei Shinkin Bank, with the combined entity to be named Shitamachi Shinkin Bank, marking another step in its evolution to serve the greater Tokyo area more effectively.
