How to say "increasingly" in Japanese

Choosing the right word
  • ますますJLPT N3approx.Common
    adverbCovers the core sense of 'increasingly', meaning more and more as something intensifies. Use it when a state or quality keeps growing stronger over time, as in increasingly difficult or increasingly popular situations.
    われわれは彼かれをますます尊敬そんけいした。↗
    We respected him all the more.
  • いよいよJLPT N2approx.Common
    adverbMeans 'more and more; all the more; increasingly', with the nuance that things are approaching a decisive or critical moment. Best when intensification is tied to a climax or imminent outcome, not just steady growth.
    いよいよ薄暮はくぼ、もうすぐ宵闇よいやみ。↗
    It's getting more and more shadowy, soon it will be twilight.
  • だんだんJLPT N1approx.Common
    adverb (with と)Really means 'gradually; by degrees; little by little'. It suits 'increasingly' only when you want to stress slow, step-by-step change rather than intensification; for plain 'more and more', ますます is usually the word you want.
    だんだん暖あたたかくなります。↗
    It will get warmer and warmer.

Use 「ますます」 for steady intensification of a state, 「いよいよ」 for something reaching a critical or decisive stage, and 「だんだん」 when you mean gradual, step-by-step change rather than intensification.
