Also called "Type B coastal defense ships," the Mikuras were improved Shimushus with heavier antisubmarine armament and a simpler design. WIth a loadout of 120 depth charges, later increased to perhaps as many as 300, these ships may be the units that were feared by American submariners as "Chidori pingers."
