Kumamoto Prefecture has a population of 1,683,115 (As of 2025 10) and has a geographic area of 7409 km2. Kumamoto Prefecture borders Fukuoka Prefecture to the north, Ōita Prefecture to the northeast, Miyazaki Prefecture to the southeast, and Kagoshima Prefecture to the south. Kumamoto is the capital and largest city of Kumamoto Prefecture, with other major cities including Yatsushiro, Amakusa, and Tamana. Kumamoto Prefecture is located in the center of Kyūshū on the coast of the Ariake Sea, across from Nagasaki Prefecture, with the mainland separated from the East China Sea by the Amakusa Archipelago. Kumamoto Prefecture is home to Mount Aso, the largest active volcano in Japan and among the largest in the world, with its peak 1592 m above sea level.

Historically, the area was called Higo Province; the province was renamed Kumamoto during the Meiji Restoration. The creation of prefectures was part of the abolition of the feudal system. The current Japanese orthography for Kumamoto literally means "bear root/origin," or "origin of the bear." However, Man'yōgana-like phonetic transcriptions based on the kanji for "a ball, a sphere" (球) and "to polish, to grind, to brush (one's teeth)" (磨) are used for the names of the Kuma River (球磨川) and Kuma District (球磨郡). The Kuma element also appears in the ancient Kumaso.
