A Western-Style Bath at an Island Inn

The Iwamotoro Roman Bath is a Western-style bathroom at a long-established inn on Enoshima (Agency for Cultural Affairs). The bath is about three bays square and covered by a glass dome.

Its walls carry a wall fountain and decoration in the manner of Venetian windows, made in tile and terracotta, and stained glass with a peacock design fills the screen between the bath and the dressing room (Agency for Cultural Affairs). The Agency records the names of the craftsmen said to have made the tiles and the stained glass.

Why It Was Registered

The Agency registered this early Showa inn bath, with its glass dome, tile, terracotta and stained glass, as something that would not be easy to reproduce.
