Developed originally as fishery protection ships, with a secondary minesweeping and tertiary convoy escort wartime function, the Shimushu class coastal defence ships (Kaibōkan) became during the war the template for the main type of oceanic convoy escorts built by the IJN. These ships were initially conceived in the early 1930s, a resurgent Russian naval presence in the Far East resulted in a number of incidents involving Japanese fisheries in disputed waters, they were consistent with the unlimited category (Article 8) of the London Naval Treaty of 1930 that allowed to build ships like the British sloops, French avisos and the American Erie class patrol gunboats, but they were effectively authorised and built only with the 1937 naval programme, after Japan had left the Treaty system and the Second London Naval Treaty had removed those quantitative limitations that justified the introduction of an unlimited category.

Originally coastal defence ship was a classification used for obsolete battleships and cruisers deemed unfit for first line duties and assigned to coastal defence, it became a separate classification that included only the new escorts in July 1942, the surviving obsolete armoured cruisers were reclassified as heavy cruisers; the new classification was also moved from the gunkan sub-group, which included main combatants like battleships, cruisers, carriers, etc. to the baseline kantei group, which included destroyers and submarines, etc..
