いやいやいや

• Reading: いやいやいや
• Romaji: iya iya iya
• Pronunciation: /i.ja i.ja i.ja/

Meaning

No no no — a rapid denial or expression of disbelief, the classic tsukkomi response to something outrageous or absurd.

Rooted in Japanese comedy's boke-tsukkomi dynamic, いやいやいや is the instinctive response of the straight man (tsukkomi) when the funny man (boke) says something ridiculous. The triple repetition conveys urgency — one いや would be a calm disagreement, but three stacked together signals 'hold on, what you just said is absolutely insane.' It has transcended comedy stages and become a universal conversational tool for expressing incredulous denial.

Examples

1. いやいやいや、それ絶対嘘でしょ？本気で言ってる？ No no no, that's gotta be a lie, right? Are you being serious?
2. 「明日までにこの仕事全部やって」「いやいやいや、無理に決まってるじゃん」 Finish all this work by tomorrow.' 'No no no, that's obviously impossible.
3. いやいやいや、なんでそうなるの？話飛びすぎでしょ。 No no no, how did you get to that conclusion? That's a huge logical leap.

Do Say

• いやいやいや、さすがにそれはおかしいでしょ。 (No no no, that's obviously wrong.)
• いやいやいや、聞いてなかったの？真逆だよ。 (No no no, weren't you listening? It's the complete opposite.)

Don't Say

• フォーマルな場で「いやいやいや」と連発するのはNG (Rapid-firing いやいやいや in formal settings is inappropriate — it sounds like a comedy routine)

Common Mistakes

• Using only one いや when trying to express strong disbelief — the repetition is what carries the comedic or emphatic force
• Mistaking it for genuine anger; いやいやいや is usually light-hearted or exasperated, not hostile

Origin & History
