Nishizawa Keikoku

Nishizawa Keikoku (西沢渓谷), a breathtaking gorge located in the Chichibu Tama Kai National Park in Yamanashi Prefecture, Japan, is a haven for nature lovers and outdoor enthusiasts. The gorge is carved out by the crystal-clear waters of the Nishizawa River, which winds its way through the valley, creating a picturesque landscape of cascading waterfalls, moss-covered rocks, and towering cliffs adorned with lush vegetation.

The hiking trails in the gorge are well-maintained and offer various routes to suit different levels of fitness and experience. The most popular trail is a circular route of approximately 10 kilometers (6.2 miles), which takes hikers past several waterfalls, including the iconic Nanatsugama-Godaisho Falls (七ツ釜五段の滝), a series of two distinct waterfalls: one with multiple cascading pools called “Nanatsugama” and another with five tiers called “Godaisho no Taki.” The trail also passes through the picturesque scenery of the gorge.

The most famous waterfall in Nishizawa Keikoku is Nanatsugama-Godaisho Falls. The area around the falls is a popular spot for picnics and photography, offering visitors a chance to relax and immerse themselves in the natural beauty of the gorge.

The autumn season is particularly enchanting in Nishizawa Keikoku, as the foliage transforms the gorge into a kaleidoscope of vibrant colors. The contrast between the fiery red and orange leaves, the emerald green moss, and the crystal-clear water creates a breathtaking spectacle that attracts numerous visitors during this time.

To reach Nishizawa Keikoku, visitors can take a bus or drive from Kofu City. Parking is available near the trailhead, and there are restroom facilities and rest stops along the trails. It is recommended to wear sturdy hiking boots and bring sufficient water and snacks, as the hike can take several hours to complete.
