Amazing tile here. When you get into the main baths you might not notice, but the back wall of the cold water bath has a new-looking alpine mountain scene that is just beautiful. But then there's more, enclosing the outdoor bath and the waterfall bath is some amazing tile. They are in a green / brown / gray glaze and mounted at different heights. The tiles themselves look like imaginary terraforms or fossil remains of plants and animal footsteps. Just outstanding. As baths go there is a great selection and everything feels extremely clean. The kind man working the front was friendly and inviting. Highly recommend sento like all places in this area.
