How to say "clumsy" in Japanese

Choosing the right word
  • na-adjective, nounCovers 'clumsy' in the sense of hopeless or lousy at a skill. It is openly derogatory — it mocks rather than describes — so it fits blunt criticism or teasing, never polite feedback.
    ヘタクソな人ひとは英訳えいやくしないでください。英訳えいやく依頼者いらいしゃからのお願ねがいです。↗
    Please don't do translations if you're crap at it. This is a plea from the English translation clients.
  • i-adjectiveCovers 'clumsy' as stiff and awkward — movement or manner that lacks natural smoothness. Typical context: a person whose motions come out stiff and unnatural, the opposite of fluid.
    彼かれは動作どうさがぎこちない。↗
    He is awkward in his movements.
  • 拙劣せつれつCommon
    na-adjective, nounCovers 'clumsy' as unskillfully done — work or handling that is poorly executed. Typical context: criticizing the clumsy way something was done or handled rather than a person's physical awkwardness.
  • 不器用ぶきようCommon
    na-adjective, nounCovers 'clumsy' in the physical sense: a person who is awkward and unskillful with their hands or body. Typical context: someone who fumbles with objects or struggles at handicrafts.
  • 無骨ぶこつCommon
    na-adjective, nounSeldom the word you want for 'clumsy': it really means unrefined, rustic, uncouth — artless and lacking polish rather than physically awkward. Its connection to 'clumsy' is marginal.
    彼かれの態度たいどはすこぶる無骨ぶこつだ。↗
    He is very blunt in his manner.

Choose 不器用 for physical clumsiness, 「ぎこちない」 for stiff, awkward movement or manner, 拙劣 for unskillfully done work, 「へたくそ」 for insulting 'lousy at it', and 無骨 only for unrefined, uncouth artlessness.
