kotoninaru (ことになる) | Meaning and Examples [JLPT N3]

ことになる (koto ni naru) indicates something that has been decided to do by circumstance. Some cases in which ことになる is used can be:

  • The conditions changed so that a certain action was allowed to happen
  • The external situation evolved independently of one's will and a decision was therefore made
  • After a discussion it was decided to do that thing
These are mostly plans and decisions that developed independently of one's will

ことになる is the opposite of ことにする: with ことにする (koto ni suru) the action one performs is for a decision made by oneself directly.
