Guida
Tashiro no Nanatsugama, located in Tokamachi City, Niigata Prefecture, is a precious scenic site designated as both a National Scenic Spot and a Natural Monument. The landscape is characterized by a unique topography where seven distinct waterfall pools are scattered along the Kama River, which flows down from the Naeba mountain range. The geological formations are academically significant, featuring cross-sectional layers on the right bank and vertical layers on the left bank. It is a place where the beauty of natural sculpting meets profound historical narratives.
The area is steeped in the "Nanatsugama Legend." It tells the story of a man who broke a promise to the deity Benten-sama—promising to catch fish with only one net—and subsequently lost his life due to the wrath of the great serpent that dwells in the waterfall pools. This legend symbolizes the deep respect and awe for nature held by the local people. Furthermore, this beautiful landscape has long captivated visitors, having been featured in the works of the Edo-period scholar Suzuki Makoshi, such as "Hokuetsu Setsuho" and "Akuyama Kiko," complete with illustrations.
The greatest attraction is the sight of the seven waterfall pools nestled within the stream, surrounded by dynamic geological exposures. In particular, the Ichiban-taki waterfall boasts a height of 21 meters, offering a truly powerful and awe-inspiring view. Although the area suffered damage from a landslide in 1995, it was beautifully restored using Japan's first "pseudo-rock" (gigan) technology for a check dam. This allows visitors to witness a reconstructed version of the original waterfall, blending natural beauty with advanced engineering. The best views can be enjoyed from the walking paths and the observation points near the Ichiban-taki waterfall.
While the scenery changes beautifully with the seasons, the period from May to August is highly recommended. During these months, the fresh greenery and the lush flow of the water create a refreshing atmosphere. In mid-July, the "Nanatsugama Festival" is held, where you can experience the local culture through the performance of the traditional "Tashiro Kagura" dance alongside the stunning natural backdrop.
Activities here primarily focus on the contemplation of natural geological art. You can walk along the maintained paths to observe the cross-sections of the earth and the shapes of the waterfall pools up close. Please note that for safety reasons, access to certain areas may be restricted; it is important to check the current status before your visit.
The area is surrounded by the rich natural environment of the Yuzawa and Uonuma regions. You can easily incorporate a visit to Tashiro no Nanatsugama into a larger itinerary exploring the historical routes and natural wonders of Niigata Prefecture.
As this is a natural valley area, comfortable walking shoes and practical clothing are highly recommended. Due to recent geological activity, please strictly follow local signage and safety instructions.
