A luxurious Sakihana Onsen bath on the top floor, beautifully shimmering in emerald green and fed 100% directly from the source. It features a mild alkaline quality and an exceptionally gentle feel on the skin, offering a triple beauty effect that helps cleanse and moisturize at the same time. There is an indoor bath, as well as the open-air baths Mizukagami and Hanakagami, which look out over the grand flow of the Agano River right before your eyes. You can enjoy an exquisite bath surrounded by seasonal scenery throughout the year.

Two private, fully reservation-based 50-minute panoramic open-air baths, Akane and Ao, are available on the top floor. Like the large public bath, these baths use the beautiful emerald-green Sakihana source water lavishly, with 100% direct flow from the source. Enjoy the magnificent view of the Agano River flowing below, the refreshing breeze crossing the river surface, and the ever-changing colors of the sky in quiet privacy, undisturbed by anyone else.
