How to say "unconventional" in Japanese

• 奇抜きばつCommon
  na-adjective, nounCovers the 'strikingly unusual' sense: things so novel or eccentric that they startle the eye. Typical of bold fashion, hairstyles, designs, or ideas that break sharply with the ordinary.
  彼かれは、奇抜きばつなアイデアを出だすため、もっと保守的ほしゅてきな同僚どうりょうと何度なんどももめごとをおこしている。↗

  His novel ideas are time and again getting him into trouble with his more conservative colleagues.
• アングラCommon
  prenominal modifierReally a noun meaning 'underground': the alternative, experimental scene in film, theater, and the like. For plain 'unconventional' it is seldom the word you want; keep it to that arts context.
• 型破りかたやぶりCommon
  na-adjective, no-adjectiveThe natural choice for people or approaches that defy convention: a mold-breaking personality, career, or idea. The nuance is refreshing nonconformity — 'outside the box' rather than merely strange.
• 破天荒はてんこうCommon
  na-adjective, nounConveys unconventionality through daring and wildness: a bold, uninhibited person who storms past convention. Colloquial, and it fits spirited characters and their exploits rather than styles or designs.

Choose 奇抜 for strikingly odd or novel styles and ideas, 「型破り」 for people or approaches that defy convention, 破天荒 for daring, wild characters, and 「アングラ」 for underground, alternative arts rather than general unconventionality.
