One of the pleasures of going to Japan is a visit to the Onsen or the Sento. The Onsen is a natural hot spring bath whereas the Sento is a heated water public bathhouse. Recently there has been a surge in so-called “super sentos”, which are large facilities with multiple baths but sometimes little character. Imai has dedicated his career to drawing people back to the small, neighbourhood, family-run sentos with his creative and thoughtful designs.
Most Japanese houses have one bathroom which everyone shares and if you ever stay in Tokyo, especially in an Air BnB, where 6 or more people share one bathroom, remember there is normally a local sento to relieve some of the pressure!
A favourite of ours is Atami-yu in the lovely Kagurazaka neighbourhood which still has a wood fired boiler to heat the water.
