Lowest One-Way Fares: Seoul Routes
Listed from cheapest to most expensive:
- Kagoshima–Seoul: ¥12,030
- Nagoya (Chubu)–Seoul: ¥14,480
- Oita–Seoul: ¥15,230
- Shizuoka–Seoul: ¥15,550
- Fukuoka–Seoul: ¥16,530
- Okinawa (Naha)–Seoul: ¥16,730
- Osaka (Kansai)–Seoul: ¥16,770
- Kobe–Seoul: ¥17,040
- Sapporo (Chitose)–Seoul: ¥18,150
- Hiroshima–Seoul: ¥18,900
- Tokyo (Narita)–Seoul: ¥19,070
The Kagoshima route is the only one in the ¥12,000 range, and it is ¥2,450 cheaper than the second-cheapest route from Nagoya (Chubu). Routes from regional airports such as Oita, Shizuoka and Hiroshima are also included. That is a real plus for travelers who want to fly to Korea from their local airport instead of first traveling to a major city.
Departures from Tokyo (Narita) at ¥19,070 and Osaka (Kansai) at ¥16,770 are at the higher end of this sale. Even so, they still come in under ¥20,000 all-in, including 15kg of checked baggage. In the Kansai area, fares from Kansai Airport and Kobe Airport differ by just ¥270, so you can choose based on access from home or departure time.
Lowest One-Way Fares: Busan Routes
- Fukuoka–Busan: ¥16,530
- Osaka (Kansai)–Busan: ¥16,770
- Sapporo (Chitose)–Busan: ¥18,150
- Tokyo (Narita)–Busan: ¥19,070
Busan routes are available from four airports: Fukuoka, Kansai, Chitose and Narita. Notably, the lowest fares from these four airports are exactly the same as their Seoul fares. Since price is not a factor, you can choose between Seoul and Busan based on your travel plans.
Both destinations are served in each direction. It may be worth searching the official website to see whether you can fly into Seoul and return from Busan.
Travel Period and Planning
The travel period runs from October 14 to December 22. It covers trips to Korea from the autumn foliage season through the run-up to Christmas. However, the year-end and New Year holidays from December 23 onward are not included.
The sale lasts only seven days, until Tuesday, October 20, which leaves five days as of this article’s publication on October 16. All listed prices are lowest fares, so not every flight or date will be available at the same price. The more flexible your schedule, the easier it will be to find the cheapest fares.
Estimated Round-Trip Cost
Doubling the one-way fare gives the following round-trip estimates:
- Kagoshima–Seoul: ¥24,060
- Nagoya (Chubu)–Seoul: ¥28,960
- Narita–Seoul and Narita–Busan: ¥38,140
These estimates assume the lowest fare can be booked in both directions. Actual fares vary by flight and date.
Things to Check Before Booking
- Listed fares are the lowest one-way prices and vary by flight, date and seat availability.
- Adding options such as seat selection may cost extra.
- The checked baggage allowance is based on 15kg. If your bag may exceed this, check the conditions when booking.
- Before booking, check the fare rules on the official website, including whether changes and refunds are allowed and any fees that apply.
- A passport is required to travel to Korea. Check its validity and the latest entry information before departure.
