“An erotic rendezvous at the bath.”
Haga Toru (1996: 97-102) explains that love-making in Edo period prints is often precarious and that artists vied with one another in inventing locations, moments and positions that expressed the sentiment of kiwadoi - the 'dangerous, risky, or pressing'. The bath, generally a public place, is a typical example of such a location: the threat of being caught and the possibilities open for voyeurism are essential for creating the sexual tension.
