How to say "intensely" in Japanese

• 無性にむしょうにCommon
  adverbThe general, common choice: a feeling, desire or urge that swells overwhelmingly, even excessively — wanting to do or have something very much, beyond control.
• がりがり
  adverb (with と)Intensely in the sense of obsessively: single-minded absorption in one thing to the exclusion of all else. A less common mimetic word, usually written in kana alone.
  佳子よしこががりがり勉強べんきょうしている。↗

  Keiko is studying furiously.
• みっちり
  adverb (with と)Intensely in the sense of severely and strictly: training, drilling or instruction pursued hard and rigorously. A less common mimetic word, it is about rigor rather than emotional intensity.
• カンカン
  adverb (with と)A mimetic word for blazing, fierce intensity: the sun blazing down, glaring light, or a person in a fury. A vivid, less common choice for such white-hot states.

Choose 「無性に」 for overwhelming feelings or urges, 「がりがり」 for obsessive single-minded focus, 「みっちり」 for rigorous, hard-driven training or instruction, and 「カンカン」 for blazing intensity, from fierce sunshine to fury.
