This might just be my favorite onsen accommodation in all of Shikoku.

Whether you choose to stay overnight or just opt for the day-use onsen, it's a fantastic choice either way. For those with tattoos, some of the rooms offer private onsen on the balcony, providing a more intimate experience.

If you love secluded hot springs as much as I do, I can't recommend this place enough. The journey to the outdoor bath itself is an adventure—you take a cable car down to the river, adding an exciting element to the experience. To be honest, I was quite scared because cable car was very steep. But it's all worth it. Bathing at the base of the valley, surrounded by the raw, untouched beauty of the Iya Valley, is an experience that leaves you speechless.
