How to say "genius" in Japanese

Choosing the right word
  • 天才てんさいJLPT N1approx.Common
    nounThe all-purpose word for 'genius': a person of extraordinary natural ability, or the gift itself. Use it whenever you would simply call someone a genius in English.
    私わたしたちは彼かれを天才てんさいだと思おもった。↗
    We thought of him as a genius.
  • 英才えいさいCommon
    nounPresents 'genius' as unusual, outstanding talent: an exceptionally able, brilliant person. Suits contexts that stress brilliance and unusual ability, such as praising a remarkably gifted individual.
  • 英俊えいしゅんCommon
    nounReally describes a person who combines exceptional talent with a strikingly handsome appearance, so it is seldom the word you want when you simply mean 'genius'.
  • 鬼才きさいCommon
    nounA genius of an unconventional, almost uncanny kind: remarkable talent that defies ordinary categories. Typical of praise for maverick creators whose work is startlingly original.
  • 俊英しゅんえいCommon
    nounAn outstanding, first-rate talent — one of the best and brightest in a field. Used to single out high achievers, as in profiles of leading figures in a profession.

Use 天才 for a genius in the ordinary sense; 英才 highlights unusual brilliance, 俊英 the best and brightest in a field, 鬼才 unconventional genius, while 英俊 adds striking looks and is seldom the right choice.
