How to say "weird" in Japanese

Choosing the right word
  • 妙みょうJLPT N3approx.Common
    na-adjective, nounCovers the mild, everyday sense of weird — something odd or curious that makes you tilt your head, like a strange story or a slightly off smell. Neutral in tone, sometimes faintly amusing.
    彼かれは自分じぶんの妙みょうな行動こうどうについて明確めいかくに説明せつめいはしなかった。↗
    He offered no specific explanation for his strange behavior.
  • 奇怪きかいCommon
    na-adjective, nounFits the stronger, more conspicuous sense of weird: things that strike you as outlandish or outrageous in their strangeness, such as bizarre events or shapes. Weightier than 妙, it suits describing something plainly strange.
    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.
  • 怪奇かいきCommon
    na-adjective, nounPoints to the uncanny, mysterious side of weird — strangeness with an eerie or supernatural flavor, the kind found in ghost stories and tales of the bizarre. Not the word for mild everyday oddness.
  • 不気味ぶきみCommon
    na-adjectiveCovers weird in the creepy, unsettling sense: things that give you the creeps, like an eerie silence or an ominous atmosphere. The emphasis is on the unease the thing provokes rather than oddness itself.
    急きゅうに笑わらい出ださないでよ。不気味ぶきみだから。↗
    Don't burst out laughing like that. It's creepy.
  • na-adjectiveA loanword for the grotesque sense of weird: strangeness through distortion or repulsiveness, as in macabre art or a distorted figure. Choose it when the weirdness is physical and disturbing rather than merely odd.
    They made huge, grotesque, yet beautiful poles of red cedar.

Use 妙 for mild everyday oddness, 奇怪 for conspicuously strange or outlandish things, 怪奇 for uncanny mysterious weirdness, 不気味 for creepy unease, and 「グロテスク」 for grotesque, repulsive distortion.
