This sale will offer domestic and international flights and hotels at special prices, along with many other exclusive special offers.

Of particular note this time are the “Second Night Free Coupon” (maximum discount of 20,000 yen, limited quantity) that can be used at all hotels in Japan, Korea, Thailand, and Taiwan, and the flat-rate airfare sale that makes overseas travel possible from 5,900 yen. The second night free coupon is also applicable to coveted hotels such as Mitsui Garden, Marriott, and Hilton chains.

In addition, over 40,000 coupons worth up to 3,000 yen off flights and hotels will be distributed, and eSIM cards, essential for overseas travel, will be available for just 88 yen. There will also be a campaign where you can get one free ticket to popular spots both in Japan and overseas, as well as sales of up to 50% off car rentals and overseas train tickets.

The “Ranking of Popular Overseas Travel Destinations for Autumn 2025,” based on flight booking data for the period from September 1 to October 31, 2025, shows that the top five destinations are all in Asia, with popularity once again this autumn concentrating on “close-by cities that are easy to visit.”

In particular, South Korea’s two major cities, Seoul and Busan, are ranked highly, suggesting that diverse travel styles are becoming more prevalent depending on the purpose, with Seoul being a capital city focused on shopping and gourmet food, while Busan is a place to enjoy beach resorts and seafood.
