How to say "groin" in Japanese
Choosing the right word
- 股またnounThe common word for the groin or crotch, and the only one here that also covers the thighs themselves. With the broadest coverage of the body senses, it is usually the word you want.
- 股間こかんnounThe crotch or groin as the area between the thighs. Less common than 股, it covers the same body sense while naming that area a little more explicitly.
- 鼠径そけいnounThe anatomical term for the groin — what medicine calls the inguinal region. Less common than 股, it belongs to medical and technical language rather than everyday speech.
- 鼠径部そけいぶnounThe same anatomical term as 鼠径 for the groin or inguinal region, with 部 ('part') presenting it as a region of the body. Less common than 股, it belongs to medical language.
- 水制すいせいnounNot a body word: this is the engineering sense of 'groin', a groyne or spur dike built from a riverbank to control the current. Never the right word for the part of the body.
For the body area use common 股, which also covers the thighs, or the less common 股間, the area between the thighs; for the anatomical groin use 鼠径 or 鼠径部; 水制 is only the engineering term, a groyne.
