The Yaeyama class is the largest class of Japan Maritime Self-Defense Force minesweepers, designed for open-sea mine clearance operations. Three ships were built in the class, a further three ships were planned but were cancelled. The ships use wooden hulls to reduce their magnetic signature and is one of the largest-sized wooden hull ships designed today.

Jane's Fighting Ships notes their similarity to the U.S. Avenger-class minesweepers.
