Abu (el. 621 m/2103 ft.) is the name of a group of volcanoes located on the coast of Japan on the southwest end of the island of Honshū.

The group is a shield volcano dating from 800,000 years ago and active into the Holocene era. The date of the latest eruption is unknown.

The group of volcanoes consists of basalt and dacitic lava flows, small shield volcanoes, cinder cones, and lava domes. Altogether, there are about 40 volcanoes, with the highest peak being Irao-yama.

Volcanic activity in the region is thought to be related to subduction of the Philippine Sea Plate.
