How to Say “I Wish You Luck” in Japanese

kouun o inorimasu
In Japanese, "I wish you luck" is expressed as 幸運を祈ります (kouun o inorimasu).
This phrase is used to express a hope that someone will be successful in a future endeavor. This phrase is quite formal and is often used in written correspondence or formal speeches rather than casual conversation.

What does it mean word for word?

The phrase is composed of 幸運 (kouun), which literally means "good fortune" or "luck".

Is there a formal and an informal way to say it?

The default form 幸運を祈ります is polite. For a more informal version used with friends or equals, you can use the dictionary form 幸運を祈る. In casual settings, you might also use Ganbare to mean "Good luck", "Do your best" or "Hang in there". In formal contexts, other variations exist: Ganbatte kudasai can mean "Please do your best" or "Good luck", Seikou o inorimasu means "I pray for your success" and Saikou no kouun o inotte imasu means "I am praying for the best of luck".

How does it change in a sentence?

The default form 幸運を祈ります uses the polite -masu verb ending.

How do you pronounce it?

kouun o inorimasu

Did you know?

  • If you use the casual 幸運を祈る with a superior, it may be interpreted as quite arrogant, as it sounds like you are granting them your blessing.
  • When using 頑張ってください (ganbatte kudasai) to wish luck, the speaker is literally asking the listener to 'persist' or 'endure', which can feel like a demand for hard work rather than a passive wish for luck.
  • The word 幸運 (kouun) shares its first character, 幸, with the word for 'happiness', meaning that wishing someone luck is linguistically linked to wishing them a happy life.

Examples in context

    Anata no seikou to kouun o inorimasu.
