Kobai Onsen (I hope I read that right) is a basic Osaka style sento south of Tenma Station. Nice selection of baths but nothing outside. Watch out for the unsigned electric bath that is in the herbal bath. You cannot see the electricity emitting pads because of the opaque brown water. Great tile work throughout the bath even if it has seen better days. Still it was very clean when I went. I enjoyed my time here and would go back if the chance arises.
