意味

A set response meaning 'have a good day' or 'take care and come back safely,' said to someone leaving home.

いってらっしゃい is the mandatory response to いってきます, completing one of Japan's most fundamental daily rituals. It literally means 'go and please come back,' expressing a wish for the person's safe return. It is said by whoever remains at home — parents to children, partners to each other, or roommates. The phrase carries genuine warmth and care, and omitting it can feel cold or worrying.

例文

1. いってらっしゃい、気をつけてね！
