Route Highlights
Yonago and Takamatsu: Regional Routes Are the Cheapest
The lowest fare in this sale is ¥12,130 on the Yonago route, followed by ¥12,690 on the Takamatsu route. Both regional-airport routes sit in the ¥12,000 range, only ¥560 apart. For residents of the San’in and Shikoku regions, these routes let you fly to Seoul from your local airport instead of traveling to a major city airport first.
Fukuoka: Under ¥15,000
The Fukuoka route is priced at ¥14,930, right in the middle of the five routes. It works for trips to Korea from the Kyushu region. Because the fares apply in both directions, it also covers itineraries from Seoul to Fukuoka.
Tokyo/Narita and Osaka/Kansai: Major-City Routes Around ¥16,000
The Narita route serving the Tokyo area is ¥15,660, and the Kansai route is ¥16,030. The two major-city routes are only ¥370 apart. Travelers from the Tokyo and Kansai areas can fly to Seoul for around ¥16,000, including fuel surcharges and taxes.
Travel Period and Trip Planning
The travel period runs from October 25, 2026 to March 27, 2027, roughly five months. It covers late autumn, winter and early spring, including Japan’s year-end and New Year holidays, winter break and part of the spring break season.
However, lowest fares are limited in number and may sell out early for popular holiday periods. If your dates are flexible, compare fares across several dates and days of the week to find prices closer to the minimum.
