The Nishizawa Keikoku is probably the most breathtaking valleys of the Chichibu-Tama-Kai National Park, a park which covers over 1250 square kilometers of forested mountains, hills, gorges and several rural towns in the prefectures of Yamanashi, Saitama, Nagano and Tokyo.

A hiking trail leads up the narrow Nishizawa Valley along a picturesque mountain stream and past several waterfalls. After about 90 minutes, you reach the valley’s highlight, the Nanatsugama-Godan-no-Taki, a beautiful five tiered waterfall. A separate, more leveled trail leads back from the waterfall to the bus stop.
The trail through the valley is steep at times, and sturdy shoes are recommended. A visit to the Nishizawa Keikoku is particularly beautiful during the autumn leaves season, which usually reaches its peak in late October and early November.
