Kumamoto Prefecture is situated in the western region of Japan's island of Kyushu, where it occupies an area of 7,408 square kilometers.
Kumamoto is bordered by the Amakusa Sea and by Fukuoka, Oita, Miyazaki, and Kagoshima Prefectures.
In present-day Kumamoto Prefecture, the primary economic activity is agriculture, with rice, vegetables, and fruit, particularly mandarin oranges, the chief crops.
Historically the area was called Higo province and was renamed to Kumamoto prefecture during the Meiji Restoration as part of the abolition of the feudal system.
Kumamoto Prefecture is located in the center of Kyushu, the southernmost of the four major Japanese islands.
Aso (1592 m), an extensive active volcano, is in the east of Kumamoto Prefecture.
