How to say "poop" in Japanese

Choosing the right word
  • うんこCommon
    noun, suru verb, intransitive verbCovers poop in its child's-word sense, matching the English gloss directly. A blunt, childish term for faeces, used when talking to small children or speaking playfully; adults using it sound juvenile or crude.
    生き物いきものなんだからウンコするに決きまってんだろ。↗
    It's a living being, so of course it shits.
  • ウンチCommon
    noun, suru verb, intransitive verbAlso a common children's word for poop or poo, essentially interchangeable with うんこ but sounding slightly softer and cuter, as with the English 'doo-doo'. Typical in speech with toddlers and picture books.

Both 「うんこ」 and 「ウンチ」 are common children's-language words for poop, used largely interchangeably; either is fine when speaking to or like a child, with 「ウンチ」 the softer, more cutesy-sounding choice.
