Kaibōkan

Kaibōkan (海防艦^?, "sea defence ship") or coastal defense ship refers to a type of naval ship used by the Imperial Japanese Navy during World War II for escort duty and coastal defense. The term escort ship is used by the United States Navy to describe this category of Japanese ships.

In the course of the war, the design was simplified and scaled down to permit larger numbers of vessels to be built more quickly.

In addition two former Chinese light cruisers were used, renamed the Ioshima and Yasoshima.
