How to say "safety" in Japanese

Choosing the right word
  • 安全あんぜんJLPT N4approx.Common
    noun, na-adjectiveThe general word for safety as an objective state: being free from danger, harm or accident. Think traffic, workplace or food safety — protecting people and property from physical danger.
    君きみは自分じぶんの安全あんぜんにもっと気きを配くばるべきだ。↗
    You should be more thoughtful of your safety.
  • 無事ぶじJLPT N3approx.Common
    noun, na-adjectiveSafety as an outcome: safe and sound, unharmed, nothing having gone wrong. Typical when reporting a safe return or arrival, or that someone has come through an accident or ordeal unscathed.
    彼かれの無事ぶじを知しらされて、部長ぶちょうは安堵あんどのため息いきをついた。↗
    Informed of his safety, the manager breathed a sigh of relief.
  • 安否あんぴCommon
    nounA person's safety or well-being as something to ask after or confirm; it fits inquiries and reports on whether someone is safe, as after a disaster, not general talk about safe conditions.
    私は彼女かのじょの安否あんぴが気きがかりなんだ。↗
    I am concerned for her safety.
  • 安泰あんたいCommon
    na-adjective, nounSafety in the sense of lasting security and stability — of one's life, position or livelihood — a settled state with nothing to threaten it, rather than freedom from immediate physical danger.
    彼女かのじょに目めをかけられれば、あなたは安泰あんたいでいられますよ。↗
    Try to stay on her good side and you'll be on easy street.
  • 安心あんしんJLPT N4approx.Common
    noun, na-adjective, suru verb, intransitive verbThe feeling of safety rather than safety itself: peace of mind, being relieved and at ease because danger or worry has passed. Choose this when English 'safe' means feeling safe, not being safe.
    あいつに仕事しごとを任まかせておけば安心あんしんだ。↗
    You can trust him with any job.

For safety as an objective state use 安全; for coming through unharmed, 無事; for asking after a person's safety, 安否; for lasting security and stability, 安泰; and for the feeling of being safe, 安心.
