How to say "excessive" in Japanese

• 過度かどCommon
  na-adjective, no-adjectiveThe plainest match for 'excessive' itself: something goes beyond a moderate or proper degree. Fits behavior or intake — drinking, worry, exercise — that exceeds a healthy or reasonable limit.
  過度かどの運動うんどうは身体しんたいのためというよりむしろ害がいになる。↗

  Too much exercise does more harm than good.
• 過大かだいCommon
  na-adjectiveEmphasizes size or amount: something is too large, too much, beyond what is warranted. Typical with estimates, demands, or expectations that are unreasonably big.
  世界的せかいてきに過大かだいに評価ひょうかされた中国ちゅうごく書しょといえば、『孫子まごこ』ですかね。↗

  When it comes to Chinese books that are overvalued worldwide I suppose it's Sun Tzu, isn't it?
• 過当かとうCommon
  na-adjective, nounCovers 'excessive' in the sense of 'exorbitant' — beyond what is fair or reasonable, as in competition or pricing. Its use is narrow; for most other senses a different word fits better.
• 甚だしいはなはだしいJLPT N2approx.Common
  i-adjectiveAn adjective for degrees that are extreme and blameworthy — it leans toward 'extreme' or 'egregious'. Typical of glaring mistakes or misunderstandings, where the excess is frankly terrible.
  あんなことを彼女かのじょに言ゆうなんて非常識ひじょうしきも甚はなはだしい。↗

  It's quite absurd of you to tell her that sort of thing.
• 余計よけいJLPT N2approx.Common
  na-adjectiveReally means 'extra' or 'more than is needed' — superfluous things, or 'too much/too many' of something. It matches 'excessive' only loosely: the idea is surplus, not going beyond a proper limit.
  余計よけいな努力どりょくの結果けっか、彼かれの血圧けつあつは通常つうじょう以上いじょうに上あがった。↗

  The extra effort raised his blood pressure above normal.

Use 過度 for going beyond a proper degree, 過大 for amounts or estimates that are too large, 過当 for exorbitant competition or pricing, 「甚だしい」 for extreme and blameworthy degrees, and 余計 for mere surplus.
