尻
shiri[ɕiɾʲi]
The Japanese word for arse is 尻 (shiri).
尻 is the standard anatomical term for the part of the body a person sits on. Beyond its literal meaning, it is frequently used in various idiomatic expressions to refer to the end or the rear of something.
Which one should you use?
尻 is the standard term, while けつ is an informal, slangy way to refer to the backside. The term ケツ is a more colloquial and potentially vulgar way to say 'arse' than 尻. For formal, medical or scientific contexts, the term 臀部 is used to describe the buttocks.
Is there a formal and an informal way to say it?
臀部 should be used in formal or medical situations. けつ and ケツ are informal, slangy or potentially vulgar expressions.
