トイレ

Etymology
, borrowed from.

Noun

 * 1) bathroom, restroom, lavatory
 * 2) toilet

Usage notes
While previously this term was considered rather crude when used to refer to the bathroom (being literally “toilet”), its usage is increasingly accepted, particularly in the younger generation – 「トイレはどこですか. 」 (“Where is the toilet?”) is generally acceptable. In polite conversation, however, is preferred.

The honorific is less often used, but is found, particularly in polite writing referring to toilets, rather than the room – if wishing to be polite when referring to the room, one would more often use お手洗い.
