During the Second World War, some Japanese scholars became passionate about studying Fuzhou dialect, believing that it could be beneficial to the rule of the Greater East Asia Co-Prosperity Sphere. One of their most famous works was the "Japanese-Chinese Translation: Fuzhou Dialect" () published in 1940 in Taipei, in which katakana was used to represent Fuzhou pronunciation.
