Can refer to nuclear family (parents and children) or extended family (grandparents, aunts, uncles, etc.)
In Japanese, '家族' can refer to both nuclear and extended family, but in everyday conversation, it often means immediate family (parents and children).
When referring to someone else's family, it's polite to use 'ご家族' (go-kazoku) instead of just '家族'.
From Middle Chinese 'kʉa-t͡sʰok' meaning 'family'
Often used in both formal and informal contexts. Can be used to refer to one's immediate family or extended family depending on context.
