How to Say “I Pooped My Pants” in Japanese

うんちを漏らした
unchi o morashita
In Japanese, "I pooped my pants" is said as うんちを漏らした (unchi o morashita).
This phrase is used to express that someone has accidentally defecated in their clothes. While the English phrase specifically mentions "pants," the Japanese phrase うんちを漏らした focuses on the act of leaking/voiding waste. The context of the accident happening in one's clothing is implied.

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

For more formal situations, such as when you need to be more indirect or polite, you can use 失礼ながら、私はおもらしをしました。 (Excuse me, but I had an accident) or すみませんが、私はトイレに行けなかったため、変なことになってしまいました。 (I'm sorry, but because I couldn't go to the bathroom, something strange happened). In very casual settings, you might hear variations like うんちを漏らしちゃって、恥ずかしかったよ。 or 言いづらいけど、実はうんこを漏らしちゃったんだよ。

How does it change in a sentence?

To make the phrase more polite or formal, you should change the verb ending to うんちを漏らしました.

How do you pronounce it?

unchi o morashita

Did you know?

  • The phrase 変なことになってしまいました (hen na koto ni natte shimaimashita) can be used to signal an accident without ever mentioning waste. It literally translates to 'it has become a strange thing', allowing for extreme social discretion.
  • The word うんち (unchi) is considered a 'child-friendly' way to refer to feces. Adults using this word in a serious situation may sound much more infantile or embarrassed than an adult using similar English slang.
  • The verb 漏らす (morasu) describes the accident as a failure of a container to hold its contents. This creates a linguistic connection between a person's body and a leaking vessel, whether the substance is liquid or solid.

Examples in context

  • 赤ちゃんがうんちを漏らした。
    Akachan ga unchi o morashita.
    The baby pooped his pants.
  • 痛すぎて、ついうんちを漏らした。
    Itsusugite, tsui unchi o morashita.
    It hurt so much that I accidentally pooped my pants.
