Tokyo to Seoul (HND–GMP) — Airlines, Schedules & Connections

Japanese passport holders enter South Korea visa-free for up to 90 days. No fee, no advance registration. Passport must be valid for the duration of stay. K-ETA (Korea Electronic Travel Authorization) was required from 2021 to 2023 but has been suspended for Japanese nationals through the end of 2025. If K-ETA resumes, it costs KRW 10,000 (about JPY 1,100) and takes 24 to 72 hours to process at k-eta.go.kr.

Entry is fast. Immigration at Incheon (ICN) typically takes 15 to 30 minutes with automated gates available for repeat visitors who register biometrics. You need a return or onward ticket and may be asked about accommodation. No proof of funds is routinely requested for Japanese passport holders. The 90-day stay cannot be extended for tourism purposes.

Direct flights from Tokyo Narita and Haneda to Seoul Incheon run about 2 hours 30 minutes, with dozens of daily frequencies on ANA, JAL, Korean Air, Asiana, Peach, T'way, Jin Air, and Jeju Air. Osaka Kansai, Nagoya Centrair, and Fukuoka also have heavy direct service. South Korea uses the Korean won (KRW), trading at roughly 9.5 KRW per JPY. T-money transit cards cost KRW 4,000 at any convenience store and work on all Seoul buses, subway, and taxis. No vaccination requirements.

Keikyu Line from Shinagawa reaches Haneda in 13 minutes (¥310). Tokyo Monorail from Hamamatsucho takes 15–22 minutes (¥500). Both run frequently from 5am to midnight. Haneda's central location makes it by far the most convenient Tokyo airport.Taxis from central Tokyo cost ¥3,500–5,500 depending on destination and traffic. Limousine buses serve major hotels and stations (¥600–1,100). Ride-shares (GO, S.RIDE) are growing in Japan. The airport is 14km from central Tokyo, significantly closer than Narita.
