Question
I’m traveling around Japan next month and this is the phrase I most need to know. Restaurants, train stations, department stores — I want to ask politely without fumbling. How do I say “Where is the bathroom?” in Japanese?
Answer by Professional Japanese Teacher
お手洗（てあら）いはどこですか。
Otearai wa doko desu ka.
Where is the bathroom?
This is the phrase I recommend for travelers. お手洗（てあら）い otearai literally means “hand-washing place” and is the polite, neutral word used in restaurants, hotels, and shops. The structure is simple: [noun] + は wa + どこですか doko desu ka, meaning “Where is [noun]?” You can swap お手洗（てあら）い for any place — 駅（えき） eki (station), コンビニ konbini (convenience store), and so on.
You may also hear トイレ toire, borrowed from English “toilet.” It is more casual but still widely used, even on signage. If you prefer something a touch more formal, 化粧室（けしょうしつ） keshoushitsu (powder room) appears in department stores and nicer hotels.
One small tip — Japanese staff usually point and say こちら kochira (this way) rather than giving long directions, so listen for that cue and follow.
