About This Tour
Guests will journey deep into the hidden region of Nagano known as Akiyamago, a remote mountain valley rich in natural beauty and cultural heritage. Here, they’ll soak in one of the wildest open-air hot springs in Nagano, where the healing waters bubble up directly from the riverbed — a rare and unforgettable experience. Important Note: The outdoor hot spring may be unavailable during bad weather if the river overflows. In that case, we’ll visit a local indoor onsen instead. The tour also includes a taste of tradition with a hearty bear meat hot pot lunch, called "Kumanabe", a local specialty passed down through generations. On the way back to Iiyama Station, we’ll stop by a local sake brewery, where guests can enjoy tasting some of Nagano’s finest rice wine. Akiyamago is usually closed off in winter due to extreme snowfall that even surpasses ski resorts, but we operate guided car tours to this remote area.
