How to say "safe" in Japanese

Choosing the right word
  • 大丈夫だいじょうぶJLPT N5approx.Common
    na-adjectiveCovers 'safe' meaning unharmed, secure or problem-free: checking whether someone is unhurt, reassuring them, or saying that a situation or plan involves no trouble. It also stands alone as a reassuring reply.
    彼女かのじょは今いまのところ大丈夫だいじょうぶです。↗
    She is all right at the moment.
  • 金庫きんこJLPT N3approx.Common
    noun'Safe' as a thing, not a state: a strong, lockable box, strongbox or vault for money and valuables. If you mean the container itself, this is the word; the others describe safety, not an object.
    貴重品きちょうひんは金庫きんこにしまっておきなさい。↗
    Put your valuables in the safe.
  • セーフCommon
    nounA loanword chiefly for sport — a baseball runner is called safe rather than out — and for casual judgments like 'that counts'; for being free of danger it is seldom what you want.
  • 無難ぶなんJLPT N1approx.Common
    na-adjective, nounSafe as in a safe choice, answer or option: one unlikely to fail, offend or draw criticism. It often carries a shade of the unadventurous — safe precisely because it stands out least.
    It is safer to say that some men and some women are good at figures.
  • 危なげないあぶなげないCommon
    i-adjectiveDescribes an action, performance or manner that shows no hint of danger or slip-ups — safe and certain, with an air of assurance. It judges how something is done, not whether someone has escaped harm.

For freedom from danger or trouble use 大丈夫, for the cash box or vault 金庫, for sports calls 「セーフ」, for an unobjectionable choice 無難, and for an assured, slip-free performance 「危なげない」.
