The Chikugo River is a river that flows through Kumamoto, Ōita, Fukuoka and Saga prefectures in Japan. With a total length of 143 kilometers, it is the longest river of Kyūshū island. It rises under the Mount Aso, and discharges into Ariake Sea, in the lower right quadrant of this orthorectified image.

The upper reaches of the river are important to forestry, and the middle and lower reaches are important to local agriculture, providing irrigation to some 400 km² of rice fields on the Tsukushi Plain. The river is also important to industry, with twenty electrical power plants are located along the banks of the Chikugo River, as well as the major city of Kurume in Fukuoka prefecture.

Kyushu, Japan - February 16th, 2009

Kyushu is the third-largest island of Japan and the most southwesterly of its four main islands. It has a population of 13,231,995 (2006) and covers 35,640 km².

Parts of Kyushu have a subtropical climate, particularly the Miyazaki and Kagoshima prefectures.

The island is mountainous, and Japan’s most active volcano, Mt Aso, at 1,591 m, is located towards its center. There are also many other signs of tectonic activity, including numerous areas of hot springs. The most famous of these are in Beppu, on the east shore, and around Mt. Aso.

Mount Aso is the largest active volcano in Japan, and is among the largest in the world. Its peak is 1592 m above sea level and is easily identifiable here by its orange-brown color around the grey caldera.

Mount Aso’s caldera is 25 km across north to south and 18 km across east to west. The caldera has a circumference of around 120 km (75 miles), although sources vary on the exact distance.

The central cone group of Aso consists of five peaks: Mounts Neko, Taka, Naka, Eboshi, and Kishima. The highest point is the summit of Mount Taka, at 1592 m above sea level. The crater of Mount Naka, contains an active volcano which continuously emits smoke and has occasional eruptions.
