How to say "fifty" in Japanese

• ５０ごじゅうCommon
  numeralThe ordinary way to write and say the number fifty, read ごじゅう; use it for the numeral itself in counting, quantities, and figures. This is the common word and almost always the right choice.
• フィフティー
  nounA katakana transcription of the English word rather than a Japanese number word; less common, and seldom the word you want for the number itself — use it only where the English term is wanted.

For the number fifty itself, ５０ is the common, everyday choice; 「フィフティー」 is a less common loanword that transcribes the English word, so reach for it only when the English term itself is wanted.
