How to say "excitement" in Japanese

• 興奮こうふんJLPT N1approx.Common
  noun, suru verb, intransitive verbThe core word for excitement as a heightened, worked-up state — a racing heart before a match or a stirred-up crowd. It can also shade into agitation or arousal, so context decides the reading.
  観客かんきゃくは彼かれのホームランに興奮こうふんした。↗

  His home run excited the crowd.
• 感動かんどうJLPT N3approx.Common
  noun, suru verb, intransitive verbExcitement in the sense of being deeply moved — the emotional stir you feel at a moving film, book, or speech. It is not the word for thrills, hype, or physical agitation.
  その小説しょうせつを読よんで深ふかく感動かんどうした。↗

  I was deeply moved by that novel.
• テンションCommon
  nounA colloquial loanword for one's energy level or mood — the buzz and hype of a party or a lively night out with friends. Expect it in casual conversation rather than formal writing.
• エキサイトCommon
  noun, suru verb, intransitive verbAs a standalone noun this loanword is marginal, and you will seldom need it for 'excitement'; treat it as a curiosity rather than a working vocabulary item.
• 挑発ちょうはつCommon
  noun, suru verb, transitive verbNot a word for the feeling of being excited: it means provocation, deliberately stirring someone up. Choose it only when 'excitement' amounts to rousing or goading another person.
  このような障害しょうがいが完全かんぜんに取り除とりのぞかれるまで、極きわめてささいな、ちょう発はつでさえ争あらそいが起おこる可能性かのうせいがいつもある。↗

  Until such difficulties are ironed out completely, there is always a chance of fighting breaking out at the slightest provocation.

Use 興奮 for heightened, worked-up excitement, 感動 for being deeply moved, 「テンション」 for casual energy or hype, while 「エキサイト」 and 挑発 are rarely the right choice for the feeling itself.
