Flights from Tokyo to Seoul
The roughly 1,180-kilometre hop between Tokyo Haneda and Seoul Gimpo is one of the busiest short-haul corridors in Northeast Asia, with a typical block time of around one hour and fifty minutes that makes it genuinely feasible as a same-day return. Korean Air, All Nippon Airways, and Asiana Airlines all operate the route, typically deploying narrow-body jets such as the Boeing 737 or Airbus A320 family, with Korean Air occasionally rotating wider equipment during peak demand. A practical point worth noting: Gimpo sits inside Seoul's city limits and connects directly to the metropolitan subway network, making city-centre arrival meaningfully faster than routing through Incheon. Both capitals share a time difference of just one hour, so schedule disruption from jet lag is negligible. Fares tend to soften during mid-winter months outside the New Year holiday window, and midweek departures on Tuesday or Wednesday often yield better availability than the notoriously packed Friday and Sunday evening banks.
