Short answer

“I miss you” in Japanese is 会(あ)いたい

How to say I miss you in Japanese?

How to say 'I miss you' in Japanese: the most natural way is 会いたい (あいたい, aitai), which literally means 'I want to see you.' Japanese doesn't have a verb that works exactly like English 'miss,' so people express the feeling as a desire to meet. 会いたい is casual; in polite speech say 会いたいです (あいたいです, aitai desu), and in more formal or humble situations use お会いしたいです (おあいしたいです, o ai shitai desu). If you want to say you feel lonely without someone, 寂しい (さびしい/さみしい, sabishii/samishii) is another common choice. Use these phrases with a partner, close friend, or family member when you want to show that you miss them.

How to use it

  • Use 会いたい as the everyday way to say “I miss you.” It is direct and warm, and it works naturally with close friends, partners, and family.
  • In polite situations, add です: 会いたいです. For something more humble and formal, especially with superiors, use お会いしたいです.
  • 寂しい is not exactly the same as “I miss you” because it means “I feel lonely.” It still works well with a partner or close friend, but it has a sadder, more emotional tone.

Common mistakes

Wrong and Correct

あなたを会いたい。 あなたに会いたい。 The verb 会う takes the particle に, not を. The person you miss is the target of the meeting, so you need に.

部長に会いたいです。 部長にお会いしたいです。 会いたいです is polite but still direct. With a superior, use the humble form お会いしたいです so it does not sound too forward or demanding.
