Short trips between two neighbours fill this route. OAG ranked Incheon–Kansai third among international routes in October 2026, with 491,573 scheduled seats, up 16% in a year. Two other Incheon–Japan routes are in the same top 10: Narita ranked first, and Fukuoka eighth with 350,326 seats. A Korean card can cost more in Japan than the price suggests. If a foreign merchant charges the card in won, KB Kookmin Bank says about 3% to 8% is added at billing. Brand and issuer fees come on top, as for any foreign purchase. A SatFares booking uses no card: the total is in US dollars, taken from a crypto balance. Pay in stablecoins; local tax and exchange rules still apply. ## Which airlines fly Incheon to Kansai? Airlines observed in our latest market fare survey include Air Seoul, Air Busan, Peach Aviation, Jeju Air, Trinity Airways, Jin Air, Asiana Airlines, Korean Air.

Asiana used an Airbus A350 on OZ 112 and OZ 114. Korean Air flew a Boeing 787-10 on KE 723. We record market fares, never our own selling price, and leave out only sanctioned airlines. The live total at checkout may be different from the survey. Our team books the ticket you choose with the airline, on request. ## How long is the flight from Seoul to Osaka?

Japan and Korea use the same clock, so that 21:00 flight lands at 22:45 local time. Osaka has a second airport in our data, Itami (ITM). This page and the survey cover Kansai (KIX). Check the airport code in your result if your plans in Osaka depend on it. ## What baggage is included on a Seoul to Osaka ticket? On Asiana in Economy, one checked bag of up to 23 kg is included on routes outside the Americas. Asiana also limits each bag to 158 cm, counting length, width and height together. We checked this on October 12, 2026. A fare on Korean Air or another airline may include a different allowance. On SatFares, baggage and fare rules (changes, refunds) are confirmed with your booking and shown on your e-ticket. The total held on your balance covers only what the fare includes, so check the airline's baggage page if you need more. ## What do I need to enter Japan through Kansai? A valid passport and, for most visitors, the right entry status for their nationality. Korean citizens on a tourist trip need no visa for a stay of up to 3 months, under the Korea–Japan visa agreement. A stay of 90 days or more needs a visa in advance.

Before landing, you can fill in immigration and customs steps on Visit Japan Web, a service of Japan's Digital Agency. Travellers with other passports should check Japanese government rules. We do not give visa advice. ## Who refunds me if my Osaka flight is cancelled? We do, under our own rule, whatever the airline's policy. If the airline cancels a flight you booked with us, you get a refund in USDT or USDC within 7 days, or a balance credit, as you choose. If the ticket can't be issued in time, nothing is charged: the hold on your balance is lifted. Passenger laws from other regions do not apply here. EU Regulation 261/2004 covers flights leaving the EU, and flights into the EU on EU airlines. The US DOT refund rule covers flights touching the United States. A cancellation you choose yourself follows the fare rules, with any refund credited to your balance. Your flight booking will be bound by the fare rules and Conditions of Carriage of the airline(s). ## How do I pay for Seoul to Osaka in crypto?

Yes, when the live search finds a flight from Incheon to Itami (ITM) on your dates. Itami is Osaka's other airport in our data. Our market fare survey and this page cover Kansai (KIX) only. The airport code appears in each result, so compare it with your plans before you confirm the booking. ### Can I book a return flight from Osaka to Seoul? Yes. The search form takes a return date as well as a departure date. The whole trip is held on your balance at checkout. It is charged only when the airline issues the e-ticket number. Each flight follows the fare rules of the ticket, which are confirmed with your booking. ### Can I pay in crypto in Osaka? Rarely. BTC Map lists only 3 places within 25 km of central Osaka, and 2 of them were verified since 2025 (October 12, 2026). We have not verified a Japanese rule on paying shops in crypto. We sell the ticket; paying on the spot is another matter. Plan to pay in yen. ### What does SatFares keep after my Osaka trip? The booking history, for 2 years, without identity documents. Passport details and dates of birth are deleted 30 days after the trip. The email address you give for the booking is never published or sold. We pass traveller data to the airline only, because the airline needs it to issue the ticket. ### What if Korean Air or Asiana changes my flight time? We send the change to the email address on the booking. That is one reason an email address is required for every booking. Other changes follow the airline's conditions of carriage. If the airline cancels the flight instead, you get a refund in USDT or USDC within 7 days, or a balance credit, as you choose. ### Can I pay for an Osaka flight with Litecoin? Yes. LTC on the Litecoin network is credited after 6 confirmations. Top up from $25, then book Incheon to Kansai from the balance. Fares are in US dollars, so the amount of LTC you need depends on its price when you top up. See [paying with LTC](https://satfares.com/pay/ltc/). ### Does SatFares add a foreign transaction fee? No card is involved, so there is no card fee from us. You pay from a crypto balance. The total shown is the fare found live for all passengers, in US dollars, taxes included, with no fee added; the final total is confirmed before you are charged. Our fee: none (no booking fee or payment fee is added). Your exchange or wallet may still charge a network fee when you send the coins to your balance. ## Sources 1.
