How to say "fifties" in Japanese

Choosing the right word
  • nounA katakana borrowing of 'fifties', typically evoking the decade of the 1950s in stylistic or cultural contexts such as fashion or music. It is less common and is not the usual way to speak of someone's age.
  • 50代ごじゅうだい
    nounRefers to the decade of a person's life from ages fifty to fifty-nine, as in 'in one's fifties'. This is the natural word for talking about someone's age, and is itself somewhat less common than alternatives.

For a person's age decade use 50代; 「フィフティーズ」 is a rarer katakana rendering of the English word, mainly for fashionable or stylistic references to the decade itself.
