Relaxation space for after bathing
Every bath at Nonoyu is a private room, not a shared hall, and there are 13 of them across three tiers: plain indoor tubs, rooms that pair an indoor bath with a small open-air one, and two Western-style indoor rooms. Most rooms also come in a choice of style, cypress tub, rock bath, or tatami-floored, each with its own garden to look out on while soaking. The spring water is smooth and faintly slick on the skin, and it runs straight from the source rather than being recirculated. While you wait, there's an irori (囲炉裏) hearth lounge to sit by, and a free footbath in the courtyard for anyone visiting. The building sits along the Koshi river in Kikuchi, and reopened after a renovation in 2021.
