How to say "belly" in Japanese

Choosing the right word
  • お腹おなかJLPT N5approx.Common
    nounThe everyday word for the belly or stomach area; the honorific お makes it polite. This is what you use in ordinary conversation when referring to your own or someone's belly.
    いいえ、結構けっこうです。お腹なかが一杯いっぱいですから。↗
    No, thank you. I've had enough.
  • 腹はらJLPT N3approx.Common
    nounThe same word without the polite prefix, blunter and more direct in tone. It is the form found in many set phrases; for talking about your belly in conversation, お腹 is the gentler choice.
    カンガルーの雌めすは子供こどもを腹はらの袋ふくろに入いれて動うごく。↗
    A female kangaroo carries its young in the pouch.
  • 腹部ふくぶCommon
    nounThe anatomical term for the abdominal region, used in medicine and technical description. For the belly of everyday speech it is not the word you want; it sounds clinical.
    その一撃いちげきは彼かれの腹部ふくぶをとらえた。↗
    The blow caught him in the stomach.

Use 「お腹」 for the belly in everyday conversation, 腹 for the same part when you want a blunter tone or a set expression, and 腹部 for the abdomen as an anatomical region.
