How to Say “Something Doesn’t Work” in Japanese

動かない
ugokanai
The Japanese phrase for "something doesn't work" is 動かない (ugokanai).
動かない is used when a machine or a mechanical device fails to operate or move. It is specifically used for mechanical or electronic failures where the device fails to move or function, rather than for abstract concepts like a plan or a system failing. If you want to specify that a machine is broken due to a mechanical fault rather than just not moving, you can use 故障している.

Which one should you use?

While 動かない describes a general state or a failure to start, 動いていない is often used to describe a machine that is currently in a state of not operating. For emphasizing that something does not work at all or lacks any functionality in an informal context, you can use 全然機能しない.

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

In a polite context, such as when speaking to staff or customers, you should use the form 動きません. For formal situations where you want to emphasize that something does not function or operate properly, 機能しない is an appropriate phrase. In informal settings, you can use 全然動かない to emphasize that something doesn't work at all. Additionally, when speaking among friends or acquaintances, adding んだ to 使えない to make 使えないんだ makes the expression more conversational and assertive.

How does it change in a sentence?

To describe a machine that is currently in a state of not operating, use 動いていない.

How do you pronounce it?

Did you know?

  • The term for 'animal', 動物 (dōbutsu), uses the same root as 動かない because it literally translates to a 'moving thing'.
  • In Japanese, you can use 動かない to describe a person who is being uncooperative or refuses to take action. If a person is described as 動かない, it means they are being stubborn or refusing to act, rather than being physically paralyzed.
  • While it often describes failure, calling a person 'unmoving' with 動かない can actually be a compliment, meaning they are steadfast or unshakeable in their convictions.
