ばよかった / てよかった Japanese Grammar Lesson

Grammar Type: Phrase

Essential Meaning: I wish X had done Y


  • Group 1 Verbs:
    • Verb conditional form + ばよかった
      • E.g. はなせばよかった [I wish X had spoken]
  • Group 2 Verbs:
    • Verb stem + ればよかった
      • E.g. べればよかった [I wish X had eaten]
  • Irregular Verbs:
    • る = ればよかった [I wish X had come]
    • する = すればよかった [I wish X had done it]


  • ばよかった is an idiomatic usage of the conditional conjunction in which some condition did not come to fruition in the past, but the speaker wishes that it had. In other words, ばよかった expresses counterfactual, wishful thinking and can be translated as “I wish X had done Y“. ばよかった conjugates just like , but it is only used with verbs and is not used with nouns or adjectives.
  • When a sentence with ばよかった does not specify a subject, the speaker is assumed to be the subject.
    • E.g. あのほんめばよかった。[I wish I had read that book.] In this case no subject is specified, so the speaker is assumed to be the subject.
  • When a third person (i.e. someone other than the speaker) wishes someone had done something, the phrase とおもっている is appended to ばよかった.
    • E.g. ビルは日本にほんけばよかったとおもっている。[Bill thinks that it would have been good if he had gone to Japan.] Here a third person named Bill is the subject, so とおもっている is appended.
  • てよかった (i.e. て-Form + よかった) is a similar grammatical structure to ばよかった. The difference is that てよかった expresses a factual past state or action, while ばよかった expresses a counterfactual past state or action.
    • E.g. あのほんんでよかった。[I’m glad that I read that book.]
    • E.g. あのほんめばよかった。[I wish I had read that book.]

先生せんせいけばよかった。[It would have been good if I had asked the teacher.]
