How to say "sloppy" in Japanese

Choosing the right word
  • 雑ざつJLPT N1approx.Common
    na-adjectiveCovers the everyday sense of sloppy work or a messy result: something done too quickly and without care, so it looks rough. Typical of work, cleaning, or handwriting.
    お客きゃくが雑ざつな作つくりのスタンドに座すわって靴くつを磨みがいてもらっている。↗
    A customer is having his shoes shined on a slapped-together stand.
  • ルーズJLPT N1approx.Common
    na-adjectiveDescribes a person who is careless or lax about time, money, or promises — always late, bad with deadlines. It judges habits and attitude, not the finish of a particular piece of work.
  • ずさんCommon
    na-adjective, nounSloppy in the sense of careless and faulty: planning, management, or work done without proper care, so mistakes and flaws result. Often written in kana alone.
    トニーは人ひとを雇やとい、もっと客きゃくを掴つかみ、仕事しごとをより早はやくずさんにやれば、もっと金かねもうけができると思おもったのだ。↗
    Tony realized that if he hired another crew, got more customers and did the job quicker and sloppier, he could make more money.
  • だらし無いだらしないJLPT N2approx.Common
    i-adjectiveSlovenly rather than merely careless: sloppy appearance, untidy dress or living habits, and a general lack of discipline. Said of people and how they present themselves or keep things.
    それ以来いらい彼かれはだらしない生活せいかつをしてきた。↗
    He has led a loose life since then.
  • 適当てきとうJLPT N4approx.Common
    na-adjective, nounSloppy in the perfunctory sense: doing a job half-heartedly, just to get it over with. The word also means 'suitable' or 'vague', so context must make the careless reading clear.

Use 雑 for carelessly finished work, 「ルーズ」 for laxness with time or money, 「ずさん」 for faulty planning, 「だらし無い」 for sloppy appearance or untidiness, and 適当 for perfunctory, half-hearted effort.
