Air Busan (BX) is running a major sale on its Japan–Busan routes. The booking window runs from August 26 to August 31, 2026 — just six days — with fares starting at an eye-catching 10 yen one way, one of the most aggressive price points seen in a low-cost carrier promotion. The travel period stretches from September 1 to December 31, covering everything from autumn getaways to year-end trips.
Sale Overview
- Booking period: August 26 – August 31, 2026
- Travel period: September 1 – December 31, 2026
- Routes: Japan – Busan
- Lowest fare: 10 yen one way (Kumamoto – Busan)
- Note: Fuel surcharges and taxes are extra
The advertised amounts cover the base fare only. Fuel surcharges, airport fees and other taxes are added at checkout, so the total payable will be higher than the headline price.
Routes and Lowest One-Way Fares
Kumamoto – Busan: 10 yen
The headline deal of the sale. At 10 yen, the base fare is effectively free, and even with taxes added the total stays remarkably low. Seat allocation is limited, so booking as early as possible is essential.
Fukuoka – Busan: 100 yen
At roughly one hour of flight time, Fukuoka–Busan is one of the easiest hops from Japan to South Korea. At 100 yen one way, a weekend dash to Busan becomes entirely realistic. It is a staple route from Kyushu with relatively frequent service.
Osaka/Kansai – Busan: 200 yen
Departing from Kansai International Airport costs just 200 yen one way. For travellers in the Kansai region, that can work out cheaper than a domestic shinkansen trip. Demand from Kansai is high, so staying flexible on dates improves your chances.
Okinawa/Naha – Busan: 2,000 yen
Naha–Busan is priced at 2,000 yen one way. Direct options between Okinawa and South Korea are limited, making this a genuinely valuable fare — useful both for Okinawa residents and for anyone combining the islands with a Korea leg.
Sapporo/Chitose – Busan: 2,500 yen
New Chitose–Busan comes in at 2,500 yen one way, giving Hokkaido travellers a nonstop link to South Korea. Winter weather can cause delays or cancellations, so build some buffer into your itinerary.

Perfect for Autumn Through Year-End in Busan
With travel valid from September 1 to December 31, the sale covers both the comfortable autumn season and the illuminated streets of late December. Busan packs a lot into a short stay: the beachfront at Haeundae, the colourful hillside lanes of Gamcheon Culture Village, the seafood stalls of Jagalchi Market, and the street food scene in Seomyeon. Airport-to-city access is also quicker than in Seoul, making Busan ideal for two- or three-day trips.
Summary
With only six days to book, the 10-yen seats will not last. Narrow down your preferred route and dates first, then check live availability on the official site. Just remember to review the change, refund and baggage rules carefully before you commit.
