A demanding full-day loop past turquoise granite pools and Nanatsugama-Godan-no-Taki waterfall, regularly ranked among Japan's most scenic gorge hikes.
Unlike many of Japan's gorge attractions, which offer a short paved walkway, Nishizawa Gorge's roughly 10 to 12-kilometer loop is a genuine full-day hiking route, following the Fuefuki River's headwaters past a sequence of named waterfalls, cascades, and turquoise granite pools. The trail's centerpiece, Nanatsugama-Godan-no-Taki, a multi-tiered waterfall recognized among Japan's 100 best waterfalls, sits roughly two-thirds of the way through the loop, after which the route crosses several suspension bridges and returns via a disused forest-railway bed once used to haul timber from the mountains. Because sections of the trail pass over uneven rock, wet log bridges, and drop-offs protected only by cable railings, sturdy footwear and reasonable fitness are necessary, and this is not a casual stroll despite its scenic reputation. The gorge closes each winter, typically from December through late April, reopening once snow and ice clear; even within the open season, waterfall flow and trail conditions vary with recent rainfall, so checking current conditions locally before setting out is worthwhile.
