How to use it

States that one is FORCED to do A because of responsibility/circumstances, even if unwilling.

  • 「Vないわけにはいかない」 = cannot not do A, meaning one is forced to do it. A double negative.
  • The direct opposite of 「Vるわけにはいかない」 (cannot do) — differing only by 「ない」.
  • Close to 「~ざるを得ない」 (more formal); this pattern feels more natural in conversation.

Examples

  • Since I was invited, I have to go.

  • Because I caused trouble, I have to apologize.

Keep in mind

  • Double negation = forced to.
  • Compare carefully with the form without 「ない」.

Common mistakes

  • Wrong行(い)くないわけにはいかない。

    Correct行(い)かないわけにはいかない。

    Must use the correct ない form: 行く → 行かない.

Exam tips

  • 「Vないわけにはいかない」 = forced to do; opposite of 「Vるわけにはいかない」.
