📝 Usage Notes

there is no way that~

📖 How to use it

Expresses strong logical impossibility: 'there is no way that ~'.

Attaches to Attach to the plain present/past form of verbs and adjectives, or to noun + である. For な-adjectives, use なわけがない (e.g., 便利なわけがない).

わけがない is used when you are certain that something cannot be true based on logic or common sense. It is stronger than はずがない and often carries an emotional tone of disbelief or frustration. The noun わけ means 'reason', so literally it means 'there is no reason (for it to be so)'.

In conversation, you will often hear it with そんな (such) or どうして (why) to emphasize that something is unthinkable. For example, if your friend says they got a perfect score without studying, you might reply 'そんなわけがない！' (That's impossible!).

Note that わけがない is not used for mere low probability—it's for absolute denial. If you're just saying something is unlikely, use はずがない or 可能性が低い instead.

こんなに難しい試験に、勉強もしないで合格するわけがない。

Konnani muzukashii shiken ni, benkyou mo shinai de goukaku suru wake ga nai.

There's no way I'll pass such a difficult exam without studying.

あの人が嘘をつくわけがない。いつも正直だし。

Ano hito ga uso o tsuku wake ga nai. Itsumo shoujiki da shi.

There's no way that person would lie. They're always honest.

こんなに雪が降っているのに、飛行機が飛ぶわけがない。

Konnani yuki ga futte iru noni, hikouki ga tobu wake ga nai.

With this much snow, there's no way the plane will take off.

Not はずがないはずがない also means 'cannot be' but is slightly less emphatic and more objective. わけがない is used when you are emotionally certain or when you find the idea absurd. Example: 彼が来るはずがない (It's unlikely he'll come) vs. 彼が来るわけがない (There's no way he'll come—it's unthinkable).
