How to say "uncommon" in Japanese

Choosing the right word
  • 珍しいめずらしいJLPT N4approx.Common
    i-adjectiveThe default word for 'uncommon' in the sense of rare or not often seen: an uncommon sight, a rare find, unusual weather. Neutral, often with a hint of curiosity or delight.
    これは珍めずらしい種類しゅるいの魚さかなです。↗
    This is a strange kind of fish.
  • レアCommon
    na-adjective, no-adjectiveA loanword from English 'rare'. Covers the same ground as 珍しい — rare, uncommon, unusual — and is at home when talking about rare finds, collectibles, or an uncommon occurrence.
  • 希代きたいCommon
    no-adjective, na-adjectiveTakes 'uncommon' to an emphatic extreme: something so rare that it is extraordinary, even matchless. Choose it when you want to stress singular rarity rather than mere infrequency.
  • 非凡ひぼんCommon
    na-adjective, nounCovers 'uncommon' as 'out of the ordinary' applied to people and their abilities: an uncommonly gifted, remarkable person. It praises exceptional talent; it is not the word for a rare object or event.
    彼女かのじょは非凡ひぼんな音楽おんがくの才能さいのうを持もっている。↗
    She has an extraordinary ability in music.
  • 異常いじょうJLPT N3approx.Common
    na-adjective, nounSeldom the word you want for plain 'uncommon': it really means 'abnormal', a state or condition that departs from the norm, often with a negative or alarming shade. Use it for abnormality, not rarity.
    そんなにたくさん食たべるのは異常いじょうだ。↗
    It is abnormal to eat so much.

Use 「珍しい」 for the everyday 'rare, not seen often'; 「レア」 as the loanword for rare finds; 希代 for emphatic, matchless rarity; 非凡 for uncommonly gifted people; and 異常 only for the abnormal, not the merely uncommon.
