I thought I had been to all the sento in this area, but I was happily mistaken. Hinode Onsen is a sleepy little place in a maze of houses and apartment buildings but surprisingly good. The baths were cooler than other sento, but the steam sauna was burning--in a good way! All complemented by a cold water bath that was not too cool or warm.
Be careful in the steam bath as the plastic dividers are missing and the scalding hot fountain that makes the steam is very much accessible.
