How to say "young" in Japanese

Choosing the right word
  • 若いわかいJLPT N5approx.Common
    i-adjectiveThe default adjective for someone or something that is young in age; it covers the plain sense 'not old' and also 'youthful'. Usually the word you want for describing a person as young.
    「彼女かのじょは若わかいですか」「はい」↗
    "Is she young?" "Yes, she is."
  • ヤングJLPT N1approx.Common
    no-adjectiveA katakana loanword that works mainly as a noun for young people rather than as an ordinary adjective; to describe a person as young, 若い is the natural choice.
  • 年少ねんしょうCommon
    no-adjective, na-adjectiveA formal word stressing young age, used chiefly in writing and official contexts about children or minors; it sounds stiff in everyday conversation about a young person.
    Television shows violence, which influences, above all, younger people.
  • 若々しいわかわかしいJLPT N2approx.Common
    i-adjectiveDescribes a youthful look, energy, or manner; often said of someone who is no longer young but seems or looks young. Use it for 'young-looking', not for simply stating someone's age.
    その年としになってもまだ彼女かのじょは若々わかわかしい少女しょうじょの面影おもかげを保たもっていた。↗
    At her age, she still preserved the appearance of a young girl.
  • 弱小じゃくしょうCommon
    na-adjective, nounIn practice this word means 'small and weak' and is used of weak countries, teams, or organizations; it does not describe a person's age, so it is seldom the word you want for 'young'.

Use 「若い」 for the basic sense of being young in age, 「若々しい」 for a youthful look or manner, 年少 for formal references to young age, 「ヤング」 as a loanword noun for young people; 弱小 really means small and weak.
