How to say "without" in Japanese

Choosing the right word
  • なしJLPT N3approx.Common
    noun, noun (suffix)The basic word for the absence of a thing: 'without' in the sense of something expected or usual being missing. Suits statements that something lacks a feature or item, and is normally written in kana.
  • せずにCommon
    adverbThe choice when 'without' concerns an action rather than a thing: doing one thing without doing another. Its second sense, 'instead of', fits when the skipped action is replaced by a different one.
    その事故じこで両親りょうしんを亡なくした少女しょうじょに同情どうじょうせずにはいられなかった。↗
    I couldn't but sympathize with the girl who had lost her parents in the accident.
  • expressionThe negative conditional 'if not', also 'otherwise; or else'. Its 'without' sense is marginal, fitting only when the lack is framed as a condition, so it is seldom the word you want for plain 'without'.
    外そとへでなさい、でないと後悔こうかいしますよ。↗
    Get out, or you will be sorry.
  • expressionAn emphatic way to say 'without': には gives the absent thing contrastive focus, underlining how much its absence matters to what follows. Use it when you want to stress the lack, not merely note it.
    この辞書じしょなしには済すまされない。↗
    I can't do without this dictionary.
  • ノーJLPT N3approx.Common
    prefixLoanword for 'no': refusal, denial, 'not needed', 'not allowed'. As 'without' it shows up chiefly in loan-style expressions, so it is rarely the word you want for ordinary 'without'.

Choose 「なし」 for the absence of a thing, 「せずに」 for doing one thing without doing another (or 'instead of'), 「なしには」 for emphatic 'without', 「ノー」 only in loan-style 'no' expressions, and 「でなければ」 mainly as 'if not'.
