How to say "excessively" in Japanese

Choosing the right word
  • adverbThe default for 'excessively' meaning 'too (much)' or 'overly': a degree that goes past what is desirable or tolerable, often with an unwanted result, as with heat, cost or tiredness.
    料理りょうりにあまりに時間じかんがかかりすぎる。↗
    Cooking takes up too much time.
  • やたらJLPT N2approx.Common
    adverb (with と)Chiefly 'indiscriminately' or 'recklessly'; when it amounts to 'excessively', the excess is unselective and without restraint — doing something an awful lot, usually with a critical nuance. Seldom the neutral choice for plain 'too much'.
    上役うわやくにやたらにぺこぺこするな。↗
    Don't be subservient to your boss.
  • 無性にむしょうにCommon
    adverbReally means 'very much' or 'intensely': an urge or feeling that swells beyond control, as in craving or longing. As 'excessively' it is marginal — it describes overwhelming desire, not excessive degree of an action.
  • むやみにJLPT N1approx.Common
    adverbA close match for 'excessively' as 'unreasonably, immoderately': going beyond sensible limits, typically with disapproval — excessive worry, spending or caution. Choose it when the excess is a matter of poor moderation rather than simple degree.

Choose 「あまりに」 for plain 'too/overly' degree, 「むやみに」 for immoderate, unreasonable excess, 「やたら」 when the excess is indiscriminate or reckless, and 「無性に」 only for overwhelming urges or feelings rather than true excess.
