The Fudo-Otaki Waterfall in Kasukawa-machi, Maebashi City, Gunma Prefecture is the most magnificent waterfall in the prefecture. It is counted as one of Japan’s 100 Fine Waterfalls. It is in the upstream of the Kasukawa River, which flows out of Lake Ko-numa near the top of Mt. Akagi-yama. The waterfall has a height of 50 m. The water dynamically falls down with roaring sounds.

With dark green leaves and acacia blossoms in early summer, fantastic mist and rainbows in summer, autumn foliage, and ice pillars in winter, the waterfall shows different scenery from season to season. Surrounded by the steep cliff formed by erosion, it is nothing but an exquisite work of natural art.

There are places of interests around the waterfall such as the rock cave where Kunisada Chuji (the Japanese Robin Hood) hid himself and Takizawa Fudoson Temple, which had been a training ashram for mountain practitioners in Mt. Akagi-yama until the Edo period (1603-1868).
