The Sumitomo Bank Building is at 2001 Franklin Street in Downtown Oakland, at the corner of Franklin and 20th Streets. The building was designed by architect Shigenori Iyama and his associate Robert Tanaka, and the bank opened in the new building on July 7, 1965. The building is now occupied by California Bank & Trust, which absorbed Sumitomo Bank in 1998. On December 31, 2015, California Bank & Trust merged with Zions First National Bank to become ZB Bank, N.A.  The former California Bank & Trust offices are operated as "California Bank & Trust, a division of ZB Bank, N.A."  Insurance companies and other small offices also rented space in the building.
