飛行機
ひこうき
hikouki
= airplane; aircraft
飛行機 (hikouki) is the standard Japanese word for airplane, built from three kanji that together paint a vivid picture: a machine that flies and goes. Whether you’re booking a ticket on ANA, spotting a contrail across a summer sky, or telling someone you’re terrified of flying, this word sits at the center of modern Japanese air travel.
飛行機 refers to any fixed-wing powered aircraft used for passenger or cargo transport. In everyday speech it covers the full range from domestic commuter flights to long-haul international jets. The particle で marks it as a means of transport — 飛行機で行く (go by airplane) — while が or は mark it as the subject: 飛行機が遅れた (the plane was delayed). It is neutral in register and used identically in casual conversation and formal announcements. The abbreviated colloquial form ひこーき with a lengthened vowel appears in children’s speech and playful adult contexts but is not used in writing.
The most common mistake is confusing 飛行機 with 航空機 (kōkūki), the technical/formal term for aircraft used in aviation regulations and news reports. In daily conversation and when buying tickets, 飛行機 is always the natural choice. A second pitfall is particle selection: use で for the means of travel (飛行機で東京へ行く) and に乗る for boarding (飛行機に乗る). Do not say 飛行機を乗る — を is ungrammatical with 乗る. Finally, note that 飛行機雲 (hikoukigumo, contrail) is a set compound; you cannot swap in 航空機 here.
飛 (とぶ / hi) means ‘to fly’ and depicts a bird with outstretched wings in its original oracle-bone form. 行 (いく / kou) means ‘to go’ or ‘to travel’ and historically showed a crossroads — the idea of movement along a path. 機 (き / ki) means ‘machine’ or ‘mechanism,’ derived from a character for a loom with moving parts. Together, 飛行機 literally reads as ‘the machine that flies and goes,’ a remarkably transparent compound that learners can decode once they know the individual kanji.

In Japan, domestic air travel is shaped by two carriers — ANA (全日本空輸) and JAL (日本航空) — whose rivalry is a fixture of business and popular culture. ANA’s blue-and-white livery and JAL’s red crane logo are instantly recognizable to Japanese travelers, and loyalty to one airline over the other can run surprisingly deep. The domestic network connecting Haneda, Itami, and New Chitose airports means that for many Japanese people, 飛行機 is a practical, routine part of life rather than an occasional luxury.
飛行機雲 (hikoukigumo), the contrail left by a jet crossing the sky, carries a distinct poetic weight in Japanese everyday imagery. It appears in song lyrics, haiku, and school essays as a symbol of faraway places, departures, and the passage of time — associations that do not map neatly onto the English word ‘contrail.’ Pointing out a 飛行機雲 on a clear day is a small but recognizable moment of shared appreciation in Japanese social life, especially among children.
