How to Say “I Need to Go to the Bathroom” in Japanese

トイレに行きたいです
toire ni ikitai desu
In Japanese, "I need to go to the bathroom" is expressed as トイレに行きたいです (toire ni ikitai desu).
These phrases are used to express the need to use a toilet. When asking for permission to use a restroom, such as at a cafe or someone's house, it is more natural to ask to "borrow" the toilet by saying トイレを借りてもいいですか? rather than simply stating your desire to go. In public spaces, you may also see the character 男 used to mark men's restrooms and 女 to mark women's restrooms.

Which one should you use?

Using お手洗い (otearai) instead of トイレ (toire) is a more polite and indirect way to refer to the bathroom in social settings. Furthermore, トイレに行かなくちゃ is a colloquial way to express the need that implies a sense of urgency.

Is there a formal and an informal way to say it?

トイレに行きたいです is a common and straightforward way to say you need to go to the bathroom in a formal setting. For a polite expression, you can use お手洗いに行きます. For a more polite and indirect way to refer to the bathroom in social settings, use お手洗いに行きたいです. If you are with friends or family, you can use the informal トイレ行きたい or the version where the です is dropped, トイレに行きたい. The phrase トイレに行かなくちゃ is colloquial.

How does it change in a sentence?

Dropping the です at the end of トイレに行きたい makes the phrase informal and suitable for use with friends or family.

How do you pronounce it?

toire ni ikitai desu

Did you know?

  • When using a public toilet, you may encounter a button for 'Otohime' (音姫), which literally means 'Sound Princess'. This is a feature that plays the sound of running water to mask any embarrassing noises you might make.
  • In Japan, you might see the word 化粧室 (keshou-shitsu) on signs in high-end department stores. While it literally translates to 'powder room' or 'make-up room', it is a very common and elegant way to refer to a public restroom.
  • In extremely formal or polite speech, people may avoid the word for 'toilet' entirely and instead use 席を外す (seki o hazusu), which means 'to leave one's seat'.

Examples in context

  • すみません、トイレに行きたいです。どこですか?
    Excuse me, I need to go to the bathroom. Where is it?
  • すみません、トイレに行きたいです。
    Sumimasen, toire ni ikitai desu.
    Excuse me, I need to go to the bathroom.
