Meaning

An adverb expressing the eventual arrival of an expected situation after a prolonged process. It conveys 'in the end,' 'finally,' or 'eventually' and can describe both positive and negative outcomes.

とうとう indicates that after a long period of time or a series of events, something has ultimately come to pass. Unlike やっと which is limited to positive outcomes, とうとう can express both welcome and unwelcome results. It carries a sense of inevitability — the speaker felt the outcome was building over time. Compared to ついに which is more literary and dramatic, とうとう is more commonly used in everyday conversation. It often appears in narrative contexts to signal the climax or conclusion of a sequence of events.

Examples

1. とうとう雨が降り出した。 It finally started raining.
2. 何度も挑戦して、とうとう山の頂上に着いた。 After many attempts, I finally reached the summit.
3. あの古い建物がとうとう取り壊された。 That old building was finally torn down.
