How to say "diving" in Japanese

Choosing the right word
  • 潜水せんすいJLPT N1approx.Common
    noun, suru verb, intransitive verbThe general word for diving or submerging underwater, as in underwater work or diving as an activity. Use this when talking about going beneath the water's surface.
    この潜水せんすい時計とけいは少すこし値段ねだんが高たかすぎます。↗
    This diver's watch is a little too expensive.
  • noun, suru verb, intransitive verbThe loanword for diving as a leisure activity or sport, especially scuba diving. It is a natural, everyday way to say 'diving' when the activity itself is meant.
    彼かれはダイビングの妙手みょうしゅだ。↗
    He is good at diving.
  • もぐりCommon
    nounCovers diving but also means a diver, with an informal feel. It is a rather casual or marginal choice for the activity; often the person rather than the act is meant.
    潜もぐりはできるが泳およげないのは、私の知しる限かぎりでは彼かれだけだ。↗
    He is the only man I know who can dive but not swim.
  • nounRefers to diving in the sports sense: simulating a foul to deceive the referee, also called flopping. This is never the word for diving into water; it is really about faking.

Use 潜水 or 「ダイビング」 for going underwater, 「もぐり」 for a diver or informal diving, and 「シミュレーション」 only for the sports sense of faking a foul.
