3. Longest River in Japan

Longest River in Japan

The general geography of Japan is mountainous with lots of narrow valleys. This topography means that rivers are short and rapid-flowing rather than long and wide, but there is also a mass of them - Hokkaido island alone has 316 rivers. The longest river in Japan, however, is on Honshu and is the Shinano. It runs for 228 miles, which is about the same as the River Severn in England and Little River in Arkansas.
