The area where the thigh meets the abdomen. In Japanese, the most common and neutral term is 鼠径部 (sokeibu), but in everyday conversation, 股 (mata) or 太ももの付け根 (futomomo no tsukene) are often used. The choice depends on context: medical, casual, or anatomical.

Talking about a groin pull, strain, or injury, often in sports or fitness contexts.

鼠径部 (sokeibu) is the precise anatomical term and is used in medical contexts. 股 (mata) is the everyday word for the crotch area, which includes the groin but can also refer to the inner thighs or the crotch of clothing. 太ももの付け根 (futomomo no tsukene) literally means 'base of the thigh' and is a descriptive, neutral way to indicate the groin area without sounding too clinical or too casual.
In English, 'groin' is a standard term even in casual contexts. In Japanese, using 鼠径部 in everyday conversation can sound overly technical or stiff. Instead, use 股 or 太ももの付け根 unless you are in a medical setting.
I can't walk because of groin pain.
