How to say "observe" in Japanese

Choosing the right word
  • 認めるみとめるJLPT N3approx.Common

    We have detected an abnormality on your x-ray.
  • 祝ういわうJLPT N3approx.Common
    godan verb, transitive verbIts only link to 'observe' is the festive one: to observe a festival is to celebrate it. For any other sense of 'observe' this is not the word you want.
    Thai Air celebrates its 50th anniversary this year.
  • みるJLPT N5approx.Common
    ichidan verb, transitive verbCovers 'observe' in the plain sense of watching or looking at something; its core meanings are to see, look, and watch, so it fits when observing simply means keeping your eyes on something.
    10ページの5行ぎょう目めをみなさい。↗
    Let's begin with the fifth line on page 10.
  • 従うしたがうJLPT N3approx.Common
    godan verb, intransitive verbCovers 'observe' in the sense of obeying or complying: you observe a law, rule, or custom in the sense of following it. Think 'abide by' rather than watching or noticing.
    A good citizen obeys the laws.
  • 守るまもるJLPT N3approx.Common
    godan verb, transitive verbAlso covers 'observe' as abiding by rules or laws, and it is the word for keeping a promise; it overlaps closely with 従う, so either can work for observing rules.
    いったん約束やくそくしたのであれば、守まもらなければならない。↗
    Once you have made a promise, you must keep it.

Pick the sense first: 「認める」 for observing in the sense of noticing something, 「みる」 for watching, 「従う」 and 「守る」 for observing rules or laws, and 「祝う」 only for observing a festival.
