About the Okinawa → Seoul route
Okinawa to Seoul is a short-haul workhorse that punches above its weight. At 1,256 km and just under 90 minutes in the air, this is barely enough time to finish a meal before you're already descending into Incheon. Six airlines compete on this route — including Korean Air (KE) and low-cost carriers like Jeju Air (7C) and T'way Air (TW) — which keeps pricing honest and scheduling frequent. The passenger mix is genuinely interesting: you've got Okinawan day-trippers, Korean tourists heading home, and a solid chunk of Japanese travelers making Seoul their first international trip.
Why travel from Okinawa to Seoul?
Seoul pulls Okinawa travelers for reasons that go well beyond sightseeing. Korean BBQ in Mapo-gu, where actual locals eat, costs a fraction of what you'd pay at a tourist-facing restaurant anywhere in Japan. K-beauty shopping in Myeongdong is a genuine draw — skincare products that aren't available in Japanese pharmacies and prices that make the flight worth it on their own. Family connection travel is huge on this route too, with a major Zainichi Korean community in Japan maintaining ties across the strait. Add in the practical pull of Seoul's concert and entertainment scene, Dongdaemun's 24-hour fashion market, and world-class Korean fried chicken that's just categorically different from anything you'll eat in Okinawa, and you've got real reasons to book.

Practical tips for OKA → ICN
Shoulder seasons — March to May and September to October — hit the sweet spot for both weather and fares. Avoid Golden Week departures from OKA unless you're booking months out. At ICN, arrival immigration is efficient but queues build fast on weekend mornings, so budget 45 minutes. The AREX express train runs directly from the airport to Seoul Station in 43 minutes for around 9,500 KRW — skip the taxi line. You'll need Korean won; grab it from the airport ATMs rather than exchanging yen before you leave. If you're flying a low-cost carrier like LJ or 7C, checked baggage is not included — carry-on only fares are common, so read the fare rules before you click buy.
