The Shimushu class escort ships (占守型海防艦 Shimushu-gata kaibōkan) were a class of ships in the service of the Imperial Japanese Navy during World War II.
The Japanese called these ships Kaibōkan, "ocean defence ships", (Kai = sea, ocean, Bo = defence, Kan = ship), to denote a multi-purpose vessel. They were initially intended for patrol and fishery protection, minesweeping and as convoy escorts. The four ships of the Shimushu class would provide the foundation for the five following classes of 171 Japanese Kaibōkan-type escort ships.
The Shimushu class was initially armed with just twelve depth charges, but this was doubled in May 1942 when their minesweeping gear was removed. The ASW weaponry would later rise to 60 depth charges with a 8 cm trench mortar and six depth charge throwers. The number of AA machine guns was increased to 15.
