About
A small day-use bath in Iwaki. The indoor tubs are live-fish transport containers, the kind you see at fish shops and markets, which gives the place its odd charm. It sits beside a fish shop and an onsen water stand where you can take the water away. Washing is basic: reviewers mention no shower and only cold water at the taps, so come ready to keep it simple.
