📖 How to use it

いよいよ marks the arrival of a long-awaited or decisive moment, meaning 'finally' or 'at last', and can also emphasize certainty.

Attaches to いよいよ is an adverb that precedes a verb, adjective, or clause; no specific conjugation is required.

いよいよ is used when something that was anticipated or built up over time is about to happen or has finally happened. It often appears with verbs like 始まる (to begin), 来る (to come), or 決まる (to be decided). For example, after months of preparation, you might say いよいよ明日出発です ('Finally, we depart tomorrow'). It carries a sense of climax or culmination, unlike the more neutral やっと (finally), which simply indicates that something took longer than expected. Additionally, いよいよ can express certainty, as in いよいよ本当だ ('It's undoubtedly true'), where it emphasizes that something is beyond doubt. This usage is common in news or formal statements.

いよいよ試験の日が来た。

Iyoiyo shiken no hi ga kita.

The day of the exam has finally come.

いよいよ明日、日本に出発します。

Iyoiyo ashita, Nihon ni shuppatsu shimasu.

Finally, tomorrow we depart for Japan.

そのニュースがいよいよ本当だと分かった。

Sono nyūsu ga iyoiyo hontō da to wakatta.

I found out that the news is undoubtedly true.

Not やっとやっと means 'finally' after a long wait or effort, but lacks the sense of a climactic or decisive moment. いよいよ often implies a major event or turning point, while やっと is used for everyday completions, e.g., やっと宿題が終わった (I finally finished my homework).

Register いよいよ is standard and used in both spoken and written Japanese; it is slightly formal but appropriate in announcements and news.
