Visit Oita

Nestled within the serene Kuju Plateau at an altitude of 1,100 meters, Akagawa Onsen is a tranquil retreat known for its extraordinary healing properties. Its most captivating feature is its rich sulfur spring, often hailed as "Japan's best sulfur cold mineral spring." Brimming with sulfur, calcium, and natural moisturizing agents, the water is said to enhance skin health, leaving it soft and smooth after bathing. Sourced naturally from three upstream springs, the onsen showcases a striking cobalt blue hue. The outdoor baths offer a unique experience where you can soak while admiring a stunning waterfall.

Akagawa Onsen also produces unique products such as soaps crafted from its spring water and concentrated onsen water that has been concentrated to 2,000 times its natural strength, which make for highly sought-after souvenirs.

The spring water itself is mild in taste and easy to drink, allowing visitors to enjoy its benefits internally as well. Take a moment to experience the full spectrum of Akagawa Onsen's therapeutic qualities, both in its baths and through its soothing water.
