How do you say “I’m happy” in Japanese?

When you are happy, you want to let the person know how you feel.

There are several ways to say “I’m happy” in Japanese.

In this article, I’ll explain how to say “I’m happy” in Japanese.


When you want to say “I’m happy”, you can use the word “うれしい (uresshii) “.

うれしい (uresshii) means “to be happy” or “to be glad”. It’s an i-adjective. The basic conjunction is:

  • うれしい(です)ureshii (desu): I’m happy.
  • うれしくない(です)ureshikunai (desu): I’m not happy.
  • うれしかった(です)ureshikatta (desu): I was happy.
  • うれしくなかった(です)ureshikunakatta (desu): I was not happy.

If you want to say it politely, add “desu” at the ending.

Watashi wa totemo ureshii desu.
I am very happy.

Oaidekite ureshii desu.
I am pleased to meet you.


Another way to say “I’m happy” is to use the word “幸せ (shiawase).”

幸せ (shiawase) is a noun that means “happiness”. As it’s a noun, you don’t have to conjugate it. You can simply say;

Watashi wa shiawase desu.
I’m happy.

Difference between うれしい and 幸せ

As I have explained, うれしい is an adjective while 幸せ is a noun. You have to conjugate うれしい, but you don’t have to do it with 幸せ.

うれしい is used very often in everyday conversations. It is a word that can be used relatively casually. On the other hand, 幸せ is stronger word of うれしい and could mean something special than うれしい.

I wish you every happiness!

This phrase is often used to celebrate the marriage of a friend or other people.
