The Katori-class training cruisers (香取型練習巡洋艦, Katori-gata renshū-jun'yōkan) were originally ordered by the Imperial Japanese Navy (IJN) to serve as training ships in the 1937 and 1939 Supplementary Naval budgets. During the Pacific War, they were used as administrative flagships for various fleets, such as submarine command and control, and to command escort squadrons. The ships were upgraded as the war progressed with additional anti-aircraft guns and depth charges.
