公衆(こうしゅう)トイレ

Compound of 公衆(こうしゅう) ('the public; general public') and the katakana loanword トイレ ('toilet'). 公衆(こうしゅう) is a productive prefix for facilities open to general public use: 公衆(こうしゅう)電話(でんわ) ('public phone'), 公衆(こうしゅう)浴場(よくじょう) ('public bathhouse').

USAGE:
Refers specifically to stand-alone toilet facilities in public places — parks, stations, along streets, at tourist sites. For toilets inside stores, offices, or homes, simply トイレ or お手洗(てあら)い is used. When directing someone to a facility, a more polite phrasing like お手洗(てあら)い is preferred.

CULTURAL NOTE:
Public toilets in Japan are famously clean and well-maintained, and are generally free to use. Many recent projects (such as the Tokyo Toilet project) treat public toilet design as an opportunity for striking architecture.
