The 'Kumaso' (熊襲) were a people of ancient
Japan, believed to have lived in the south of
Kyūshū until at least the
Nara period. Their name, Japanese for "bear people", is most likely a description resulting from embellished tales of their physical features (similar to the
Tsuchigumo, whose name means "ground spider"). As the
Yamato pushed southward, the Kumaso people were either assimilated or exterminated. The last "King" of Kumaso was assassinated by Prince Yamatotakeru of Yamato and the Kumaso kingdom came to the end. The name of
Kumamoto Prefecture comes from the Kumaso. Some people believe there are still Kumaso people living in rural Kyūshū, or that there were until as late as the early
20th century.
They are believed to have spoken an Austronesian language.
