How to say "rare" in Japanese

Choosing the right word
  • 珍しいめずらしいJLPT N4approx.Common
    i-adjectiveCovers 'rare' as 'uncommon, out of the ordinary', with a nuance of 'interesting because seldom seen' — the word for an unusual dish or a sight you hardly ever encounter.
    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-adjectiveThe katakana loanword. This is the word for meat cooked rare, as when ordering steak, and it also describes things that are hard to come by, such as items collectors seldom find.
  • まれJLPT N2approx.Common
    na-adjectiveCovers 'rare' in the sense of frequency: events, cases or abilities that occur only occasionally. It also serves for 'seldom', and it is usually written in kana rather than with kanji.
    チャンスというものはいずれにしても、まれにしかない。↗
    Chances come rarely in any case.
  • 珍ちんCommon
    na-adjective, nounGlossed plainly as 'rare', but this is really a combining element, not a stand-alone word, and on its own it is seldom how you say 'rare'. For that meaning you want the adjective 珍しい.
    あの珍本ちんぽんをどうやって手てに入いれたのですか。↗
    How did you come by those rare books?
  • 希少きしょうCommon
    na-adjective, nounThis word leans toward 'scarce': think of dwindling resources or wildlife found only in small numbers, not of things that are merely unusual.
    古代こだいにおいて塩しおは希少きしょうで貴重きちょうな商品しょうひんであった。↗
    Salt was a rare and costly commodity in ancient times.

Use 「珍しい」 when something is simply uncommon or unusual, 「レア」 for steak and hard-to-find items, 「まれ」 for things that seldom happen, 希少 for scarce resources or wildlife, and treat 珍 as a combining form, not a stand-alone word.
