Seoul is the No. 1 overseas destination for Japanese travelers this autumn. In its "2026 Autumn Overseas Destination Popularity Ranking," announced on October 21, 2026, the Japanese travel comparison site Travelko put Seoul at the top of the list, ahead of Taipei in second place and Busan in third. Travelko is operated by Open Door Inc., based in Tokyo.
The ranking is based on search counts on Travelko — not on bookings. It covers searches made between September 1 and 30, 2026, for travel between October 1 and November 30, 2026. Travelko itself is explicit on this point: the ranking shows the order of search volume, not booking results. It is a snapshot of where Japanese travelers are looking, not a count of who actually went.
The top 10 is dominated by nearby Asia: after Seoul, Taipei, and Busan come Hong Kong, Honolulu, Bangkok, Guam, Singapore, Shanghai, and Hanoi. The standout mover is Singapore, whose searches rose 134% on the same period last year, climbing from No. 10 to No. 8. Meanwhile, the long-time favorites Honolulu and Guam held their popularity.
This is what the ranking measures, who made the top 10, why Singapore surged, and how to read a search ranking before planning an autumn trip.

What Is Travelko's Autumn Ranking?
Travelko is a Japanese travel comparison site run by Open Door Inc. (headquartered in Minato-ku, Tokyo). Its autumn ranking is drawn from search data on the Travelko site: searches made from September 1 to 30, 2026, for trips taking place between October 1 and November 30, 2026.
The key fact about the ranking is what it counts. It counts searches, not reservations and not arrivals. A destination can top the list because many people are dreaming about it, comparing prices, or weighing options — not because the most people booked it. That distinction matters for everything else in this article.
Travelko publishes seasonal rankings of this kind regularly, using the same search-data method. The autumn 2026 edition was released as a press release on October 21, 2026, and covered by Japanese travel trade media the same week.
Who Made the Top 10?
The full top 10, in order:
1. Seoul
2. Taipei
3. Busan
4. Hong Kong
5. Honolulu
6. Bangkok
7. Guam
8. Singapore (up from No. 10 last year)
9. Shanghai
10. Hanoi
Eight of the ten are in Asia; the two exceptions are the Pacific resort destinations Honolulu and Guam. The top three — Seoul, Taipei, and Busan — are all short-haul destinations from Japan, and Travelko notes that demand for nearby Asia, where trips are affordable and fit into short schedules, stayed strong this autumn.
The ranking reflects Japanese travelers only. It says nothing about travelers from other countries, and it is not a global popularity contest — but for anyone watching East Asian travel demand, it is a clear signal of where Japanese attention is going this season.
What Does the Ranking Show About This Autumn?
The main pattern is proximity. Travelko attributes the continued strength of nearby Asian destinations to trips that are easy on the budget and workable in a short schedule — the kind of autumn break that fits a long weekend or a few days off.
The other pattern is loyalty to the classics. Honolulu and Guam kept their popularity, Travelko said, despite the near-Asia surge. They are the established resort choices for Japanese travelers, and they held their places in the top 10 even as the list around them shifted.
Seoul's No. 1 position also fits a wider moment for the city. In a separate ranking published earlier in October, Condé Nast Traveler's U.S. readers voted Seoul the world's best big city for 2026 — a different survey, with different voters, but the same direction of travel. The Travelko ranking adds a Japanese perspective to that picture: Seoul is the destination Japanese travelers are searching for most this autumn.
Why Did Singapore Surge?
Singapore is the ranking's biggest mover. Its search count rose 134% compared with the same period last year, lifting it from No. 10 to No. 8 — the largest jump in the top 10.
Travelko itself offered possible reasons, and they should be read as the company's own view, not as proven causes. The company pointed to new attractions and entertainment facilities in Singapore — including the Disney Adventure cruise ship and the Exploria attraction in the Mandai Lake area — together with more seats on medium- and long-haul low-cost carriers, including ZIPAIR and Scoot. In Travelko's reading, those factors combined to push searches up.
What is certain is the number: searches up 134% year on year, and a two-place rise. The explanation is Travelko's interpretation. Either way, Singapore is the destination to watch in this ranking — the one whose momentum is new, rather than a continuation of last year's order.
What Should Travelers Take From a Search Ranking?
A search ranking is a planning signal, not a result. Treat it as a list of places people are interested in right now — useful for inspiration, and for a warning that the most-searched places may also be the ones where flights and hotels get booked up first.
A few practical points follow from that:
Search interest is not availability. Check actual flight and hotel prices for your dates before assuming a top-ranked destination is affordable.
Popularity can mean crowds. If you are set on Seoul, Taipei, or Busan this autumn, booking earlier gives you more choice.
Rankings change every season. This one covers a single search window in September 2026; the winter ranking may look different.
The ranking is most useful as a snapshot of demand — a sense of where attention is going, and where early booking pays off.
Planning an Autumn Trip to Seoul?
If Seoul is on your list, the autumn version of the city is the one in the ranking's own imagery: palace grounds and mountain parks in red and gold. Gyeongbokgung Palace, the city's grandest Joseon-era palace, is the classic autumn walk, and N Seoul Tower gives the wide view of the city in its autumn colors.
A simple plan for a first autumn trip:
Start at Gyeongbokgung in the morning, when the palace grounds are quietest.
Walk to Insadong for tea houses, crafts, and galleries in the afternoon.
Save N Seoul Tower for sunset, when the city lights come up.
Dress for cool weather — autumn mornings and evenings in Seoul can be chilly.
Confirm opening hours and admission before you go, as they vary by season.
Seoul is also the top-ranked destination in this survey for a reason that goes beyond one season: palaces, food, shopping, and modern neighborhoods in a single compact city. The ranking says Japanese travelers are searching for it more than anywhere else this autumn. The search data does not prove it is the best trip for everyone — but it is a good reason to look.
