How to say "fitness" in Japanese

Choosing the right word
  • nounCovers the physical sense of fitness: exercise, health, and keeping in shape. This katakana loanword is the word you want here; it does not extend to the abstract 'fitness for a purpose' sense.
  • 適否てきひCommon
    nounCovers 'fitness' only as suitability — whether a person or thing is fit for a purpose. It does not refer to physical fitness, so for exercise and health it is not the word you want.

Use 「フィットネス」 for physical fitness — exercise, health, and keeping in shape — and 適否 only for the abstract sense of fitness as suitability, that is, whether a person or thing is fit for a purpose.
