About

This is a municipally run bathing center outside Hitachiota, with an indoor bath, a rotenburo facing the surrounding hills, and a sauna (there's no cold plunge, just a hand shower). The water is alkaline and smooth on the skin. A tatami rest area and a dining hall round it out, useful if you want to linger after bathing rather than just pass through.
