Hachijo (八丈, Hachijō) was one of four Shimushu-class escort ships built for the Imperial Japanese Navy during World War II.

The ships had two diesel engines, each driving one propeller shaft, which were rated at a total of 4,200 brake horsepower (3,100 kW) for a speed of 19.7 knots (36.5 km/h; 22.7 mph).

A dozen depth charges were stowed aboard initially, but this was doubled in May 1942 when their minesweeping gear was removed.

On 19 February 1943, Hachijo barely missed meeting her doom when she was detached from escorting Akagane Maru to Attu in the morning.

That evening, Akagane Maru ran into the heavy cruiser USS Indianapolis with two destroyers and was sunk.
