How to say "sailing" in Japanese

Choosing the right word
  • 便びんJLPT N3approx.Common
    noun, noun (suffix)Covers a scheduled sailing as a departure or service, like a ferry crossing booked by time, alongside flights and train trips; it counts individual sailings rather than describing the activity of sailing.
    ちょっとした事故じこが原因げんいんで、2、3便びんに遅おくれが出でた。↗
    A couple of flights were delayed on account of a minor accident.
  • 航海こうかいJLPT N1approx.Common
    noun, suru verb, intransitive verbRefers to a sea voyage or passage, especially a long one, and to sailing as such; choose this when 'sailing' means the voyage across the sea itself, as in an ocean crossing.
    そのヨットは順調じゅんちょうに航海こうかい中ちゅうだ。↗
    The yacht is under smooth sail.
  • 航行こうこうCommon
    noun, suru verb, transitive verb, intransitive verbFocuses on cruising or navigation, the act of a vessel moving through the water; suits contexts about a ship sailing on a route or its navigation, rather than a voyage as an event.
    そのヨットはブイを回まわって航行こうこうした。↗
    The yacht sailed round a buoy.
  • 航法こうほうCommon
    nounReally means navigation as a method or technique, the skill of working out a course; it is seldom the word you want for 'sailing' in the sense of a voyage or of a boat moving under sail.
  • 帆走はんそうCommon
    suru verb, intransitive verb, no-adjectiveSpecifically sailing under sail, a boat propelled by its sails; use this only when the English 'sailing' refers to that activity, not to a scheduled sailing, a voyage generally, or navigation.
    船ふねを帆走はんそうさせると私達わたしたちは楽たのしくなる。↗
    Sailing a boat makes us happy.

For a scheduled ferry or flight departure use 便; for the activity of navigating a boat use 航海, 航行, or 帆走 (under sail specifically); 航法 is really the technique of navigation, not the voyage itself.
