How to say "triumphant" in Japanese

• 鼻高々はなたかだかCommon
  na-adjectiveThe common, everyday choice: feeling proud and triumphant about something, often visibly so. It can carry a hint of boastfulness or self-satisfaction, so it suits pleased-with-oneself moments.
• 揚々ようよう
  taru-adjective, adverb (with と)Covers the exultant, high-spirited sense of triumphant. It is less common, and in meaning it matches 意気揚々, the fuller four-character form that conveys the same idea.
• 意気揚々いきようよう
  taru-adjective, adverb (with と)A four-character idiom for being triumphant and exultant, in high and proud spirits — the picture is someone brimming with elation after a success, such as returning from a victory.
  ワールドカップで優勝ゆうしょうした全日本ぜんにっぽんチームは、意気揚々いきようようと帰国きこくしてきた。↗

  The Japanese World Cup champion team came back home flushed with victory.
• 鬼の首を取ったようおにのくびをとったよう
  expression, na-adjectiveNot a neutral way to say triumphant: it mocks someone who acts triumphant over a mediocre achievement, as if they had grabbed a demon by the neck. A derisive comparison, not a compliment.
• 昂然こうぜん
  taru-adjective, adverb (with と)A less common word depicting a proud, elated bearing — head held high in triumph — rather than quiet inner joy; the pride is on open display and can read as haughty.

Use 鼻高々 for the everyday sense of feeling proud and triumphant; 意気揚々 (or the shorter 揚々) for exultant high spirits; 昂然 for proud, head-high bearing; 「鬼の首を取ったよう」 mocks triumph over something trivial.
