Lowest One-Way Fares: Seoul Routes

Seoul routes link the city with 11 airports in Japan. The cheapest is Shizuoka at ¥14,050. Even the most expensive route, Tokyo (Narita), costs just ¥19,570, so every route is under ¥20,000 one-way.

Seoul – Shizuoka: ¥14,050
Seoul – Matsuyama: ¥14,730
Seoul – Hiroshima: ¥16,400
Seoul – Fukuoka: ¥16,530
Seoul – Kagoshima: ¥16,730
Seoul – Nagoya (Chubu): ¥17,180
Seoul – Okinawa (Naha): ¥17,230
Seoul – Osaka (Kansai): ¥17,570
Seoul – Oita: ¥17,730
Seoul – Kobe: ¥18,840
Seoul – Tokyo (Narita): ¥19,570

A highlight of this sale is that it includes regional airports outside the Tokyo and Kansai areas, such as Shizuoka, Matsuyama, Hiroshima, Kagoshima and Oita. Shizuoka and Matsuyama, the two cheapest routes, are both in the ¥14,000 range. Flying from an airport close to home saves you the time and cost of traveling to a major city airport.

Tokyo, Nagoya, Osaka and Kobe

Fares from the major metropolitan airports are ¥17,180 from Nagoya (Chubu), ¥17,570 from Osaka (Kansai) and ¥19,570 from Tokyo (Narita). In the Kansai region, Kobe Airport (¥18,840) is also included alongside Kansai International Airport. When choosing where to depart from, it is worth factoring in how you will get to the airport.

Lowest One-Way Fares: Busan Routes

Busan routes cover three destinations: Fukuoka, Osaka (Kansai) and Tokyo (Narita).

Busan – Fukuoka: ¥16,530
Busan – Osaka (Kansai): ¥17,570
Busan – Tokyo (Narita): ¥19,570

All three are priced the same as the Seoul route from the same Japanese airport. For example, from Fukuoka you can fly to Seoul or Busan from ¥16,530. Because the price is the same, you can pick your destination purely on what you want to do. If you want to fly into one Korean city and return from the other, check one-way fares and booking conditions on the official website in advance.
