Nishizawa Gorge, the riverhead of the Fuefuki River, is located in the bordering area of Saitama, Yamanashi and Nagano prefectures, which is a part of Chichibu-Tama-Kai National Park. The gorge has a lot of scenic spots such as pit holes made by erosion, Botai-buchi (a deep pool) and many strange rocks including Kaeru-iwa Rock, which looks like a parent frog carrying its child frog on its back, Jinmen-do Cave, the surrounding rock surface of which looks like a human’s face. There are also many waterfalls in the gorge such as the Okubo Fall, the Ryujin Fall and the Koiito Fall. The highlight is the Nanatsugama Godan Fall (7 basins and 5 stages fall), which is divided into two parts: the upper 3 stages and the lower 2 stages. This cute waterfall is selected as one of Japan’s 100 Fine Waterfalls. The gorge and its surrounding mountains are covered with red and yellow leaves in fall. The gorge was designated as one of 100 Sites Worthy of Preservation into the 21st Century by the Forestry Culture Association. As the walking promenade and bridges are fully arranged along the gorge, a lot of hikers come to enjoy bountiful nature.
