Following the announcement of an ambitious shipbuilding program by the U.S. in 1919, Japan reconsidered the plans for the development of its Navy and gave the order to build four more battleships and four more battlecruisers. The design of the battleship incorporated five 410 mm twin-gun turrets and a 12-inch main armor belt. The first two ships were ordered for construction in 1921, but preparations were suspended due to the Washington Naval Conference. The ships were never built.
