The Tamagawa Onsen Nature Study Trail is a walking path located in Towada-Hachimantai National Park in Tamagawa, Tazawako, Senboku City, Akita Prefecture.
This approximately 30-minute trail winds through the source area of Tamagawa Onsen, renowned for its powerfully acidic hot springs, said to be the largest in Japan.
As you walk, you'll encounter steam rising from the ground and the distinctive scent of sulfur. The trail is surrounded by a serene primeval forest of beech and Sakhalin fir, creating a tranquil and peaceful atmosphere.
Along the way, you'll find spots perfect for natural rock bathing (ganbanyoku). This experience offers deep body warmth, promoting blood circulation and potentially boosting metabolism.
The Tamagawa Onsen Nature Study Trail is a highly recommended spot to enjoy the abundance of nature and the blessings of the hot springs.
The "Dai-fun" (Great Eruption), where 9,000 liters of highly acidic hot springs gush out every minute, is truly awe-inspiring. The hot springs flowing from Dai-fun are also known as a source of Hokutolite, a rare mineral designated as a Special Natural Monument of Japan. Its rarity has made Tamagawa Onsen a revered "healing hot spring destination" for centuries.
Experience the raw power of nature and revitalize your mind and body on this unforgettable trail.
