Air Seoul Launches a Last-Minute Japan–Korea Sale
Air Seoul is running a promotion called “Last Minute! Late Summer Getaway & Welcome Autumn Special Discount” on its Japan–Korea routes from August 4 to August 17, 2026. The limited-time offer targets both travellers squeezing in a final summer trip and those already planning autumn journeys, with one-way fares starting at 13,040 yen.
All fares announced in this sale are all-in totals that already include fuel surcharges and taxes. When comparing airfares, headline prices often look cheap until surcharges and taxes are added; here, the quoted totals mean a one-way hop between Japan and Korea can be had for just over 10,000 yen.
Routes and Minimum One-Way Fares
The eligible routes and lowest one-way fares are listed below. All operate to and from Seoul/Incheon, and prices include fuel surcharges and taxes.
- Seoul/Incheon – Yonago: 13,040 yen
- Seoul/Incheon – Takamatsu: 13,600 yen
- Seoul/Incheon – Fukuoka: 15,340 yen
- Seoul/Incheon – Tokyo/Narita: 16,460 yen
- Seoul/Incheon – Osaka/Kansai: 16,480 yen
The cheapest option is the Yonago route, the gateway to the San’in region, at 13,040 yen, followed by Takamatsu in Shikoku at 13,600 yen, showing that regional routes hold the price advantage. Even the high-demand Narita and Kansai routes stay in the 16,000-yen range, which works out to roughly 30,000-something yen for a simple round trip.
Regional Airports Offer Handy Access
The Yonago route suits trips to Sakaiminato, Matsue and the Izumo area, while Takamatsu opens the door to Kagawa’s udon trail and Setouchi islands such as Naoshima and Shodoshima. Beyond travellers heading from Korea to regional Japan, the routes are also a strong option for residents of regional Japan connecting via Incheon to destinations across Korea and Asia.
Sales and Travel Periods
Tickets are on sale from August 4 to August 17, 2026, with a travel period running from August 4 to October 24, 2026 — a window of nearly three months. That covers short trips using the remainder of the summer break, the September holidays and the first half of the October autumn-foliage season.
Seat availability is limited, however, and the sale ends as soon as the allocation sells out, potentially before the stated deadline. Popular dates and weekend departures typically fill first, so travellers with fixed plans should book early.

- Seats are limited and the promotion ends once they are gone

Summary
Alongside fares from 13,040 yen one way, this sale is easy to evaluate because prices are shown as all-in totals including fuel surcharges and taxes.
