List of battleships of Japan
Between the 1890s and 1940s, the Imperial Japanese Navy (IJN) built a series of battleships as it expanded its fleet. Previously, the Empire of Japan had acquired a few ironclad warships from foreign builders, although it had adopted the Jeune École naval doctrine which emphasized cheap torpedo boats and commerce raiding to offset expensive, heavily armored ships.
