The Sanwa Bank (株式会社三和銀行, Kabushiki gaisha Sanwa Ginkō) was a major Japanese bank headquartered in Osaka, which operated from 1933 to 2002. It resulted from the merger of three local banks, Konoike Bank (est. 1877 as 13th National Bank), 34th Bank (est. 1878), and Yamaguchi Bank (est. 1879 as 148th National Bank).
In 2002, Sanwa Bank merged with Tokai Bank and Toyo Trust and Banking to form UFJ Bank, itself a predecessor entity of Mitsubishi UFJ Financial Group.
