What Sound Do Mice Make in Japanese? Meet the Tiny, Squeaky “Chuu!” of the Japanese Mouse!

You might know the sound of a mouse as “squeak” in English.

In French, it’s “cui-cui.”

In Korean, it’s “jik jik.”

But in Japanese, the sound of a mouse is often written as —
Chuu! (ちゅう!)

It’s soft, high-pitched, and just a bit mischievous.
You’ll hear it in anime, manga, and children’s songs — especially when a little mouse appears and goes… Chuu!

Let’s listen to what it sounds like!

What is “Chuu” (ちゅう)?

“Chuu” is the Japanese onomatopoeia for a mouse’s squeak — especially the small, light sound they make when sniffing around or being startled.

It captures that tiny, cute, almost whisper-like sound.

You’ll often hear “chuu” in:

  • Picture books and children’s stories
  • Anime and manga (especially with mascot characters!)

Pronunciation

choo
(Like “chew,” but with a gentle, rising pitch.)

Say it lightly — like a breathy sound floating through the air.

What Does “Chuu” Look Like?

In manga, “Chuu” is often drawn next to a small round mouse character, peeking out from behind a wall or stealing cheese.

It’s usually written in soft, round letters — matching the gentle and cute nature of the sound.
