Breakfast included ; 2 peopleTax included¥23,760〜
(USD 149.66)

An Accommodation featuring terraced open-air baths overlooking the Okawa Valley, where you can experience Aizu’s four seasons.

At Okawaso, a new onsen facility has been established where you can immerse yourself in warmth to your heart's content. The terraced rice field-style open-air bath 'Shikibutai Tanada' offers a sense of unity with the beauty of the valley. Spacious indoor baths. Two saunas, the 'Gorone-style Bakuhanseki Sauna' and the 'Pink Salt Sauna,' with far-infrared effects to relieve fatigue from deep within the body, have also opened simultaneously. A spa room for women is also available, allowing you to enhance your beauty during your travels and refresh both body and mind.

    I stayed here for Demon Slayer, and the atmosphere was exactly as I imagined. The meals were excellent, and I’d love to come again. (I did feel the portions were a bit large.)It was disappointing that the air conditioning didn’t seem adjustable—the Room was a little hot, and even if I wanted to open a window, it couldn’t be opened. As for the open-air bath in midair, I think it really needs a proper washing area, including showers.

  • A superb Onsen Accommodation! Perfect in every way except the meals.

    It’s been getting attention for resembling the Infinity Castle from *Demon Slayer*, and I was really looking forward to staying here. As soon as you enter the Ryokan, the view opening up from the front desk is breathtaking!! Around 4:00 PM, a shamisen performance began on the stage, and the performer’s movements were so graceful I could have watched forever. The terraced open-air bath was spectacular, and we enjoyed snowy views of the nearby mountains and valley. The water temperature was perfect and incredibly relaxing. The other large public bath—the sky open-air bath—can be reserved for private use depending on the time slot for 3,300 yen, but you should definitely make a Reservation during daylight hours. We called to reserve it the day before, but unfortunately only nighttime was available; we used it in the morning during regular hours instead, and it was still wonderful. Both the property and our Room were clean, and we were able to relax a lot—but the shower water pressure in our Room was very weak (lol). The only real disappointment was dinner. We had a Japanese course meal at the restaurant, but it felt unbalanced with too many soups/dishes with broth, and everything came out far too quickly. The tempura batter was overly crunchy and tasted amateurish, which was really disappointing. I wondered if we should have chosen the other restaurant where you can enjoy kappo cuisine prepared by the head chef instead. The breakfast buffet was delicious. The staff were polite as well—overall, aside from that, it was truly a great Accommodation.
