Meaning
The phrase “腕が鳴る” (My arms are making a sound) is a Japanese idiom that expresses eager anticipation to show one’s skills or abilities.
It’s used when someone feels excited or fired up to take on a challenge, especially when they finally get a chance to prove their talent.

This idiom is not just “I’m excited.” It typically carries three ideas:
- You have confidence in your ability (or at least pride in it).
- The situation is a good match for your skills—something that “calls for” your talent.
- You feel competitive / motivated because the task looks challenging or meaningful.
That’s why it is common in contexts like sports, competitions, work projects, cooking, crafts, programming, negotiations, and performances.
腕 (ude) can mean your “arm,” but in Japanese it also means skill / ability (like “腕前 / udemae”).
You can use 腕が鳴る when:
- you get a difficult opponent (sports, games, debate)
- you’re assigned a challenging project at work
- someone asks you to do something you’re good at (cook, design, fix, build)
- you finally have a stage to show your ability (audition, contest, presentation)
Example sentence
次の試合は強い相手だけど、こういう相手ほど腕が鳴るね。
The next game is against a tough team, but I’m excited to put my skills to the test.

More examples:
- 新しいメニューを任された。料理人として腕が鳴る。
I’ve been put in charge of a new menu. As a chef, I’m itching to show my skills. - 難しい案件だけど、腕が鳴るよ。
It’s a tough project, but I’m excited to show what I can do.
