How to say "mysterious" in Japanese

Choosing the right word
  • na-adjectiveThe direct borrowing of English 'mysterious', used much as in English, typically for a person or atmosphere that has an air of mystery or enigmatic allure.
  • 不可解ふかかいCommon
    na-adjective, nounCovers the 'inexplicable' side of mysterious: something baffling that resists understanding or explanation, such as puzzling behavior or an unaccountable event, without any suggestion of charm.
    愛あいの動うごきは不可解ふかかい。↗
    Love moves in mysterious ways.
  • 神秘的しんぴてきCommon
    na-adjectiveThe closest match for the alluring sense: something imbued with mystical, otherworldly mystery that inspires awe, as with a haunting landscape or an enigmatic presence.
    それは壁かべに神秘的しんぴてきな影かげを投なげかける。↗
    It casts mysterious shadows on the wall.
  • 不思議ふしぎJLPT N3approx.Common
    na-adjective, nounA broad word covering 'strange' and 'wondrous'; for the everyday sense of mysterious — something odd or hard to explain — this is the natural, all-purpose choice.
    この刀かたなには不思議ふしぎないわれがある。↗
    This sword has a strange history.
  • 奇怪きかいCommon
    na-adjective, nounReally means 'bizarre' or 'weird': strangeness that is outlandish or grotesque rather than enigmatically mysterious, so it is seldom the word you want for 'mysterious'.
    彼かれは奇怪きっかいな体験たいけんを詳くわしく話はなした。↗
    He recounted his unusual experiences.

Choose 神秘的 for alluring, otherworldly mystery, 不可解 for the baffling and inexplicable, 不思議 for everyday strangeness, 「ミステリアス」 as the direct English borrowing, and 奇怪 only for the bizarre.
