Flights from Tokyo to Seoul
Tokyo Narita to Seoul Incheon is one of the busiest short-haul corridors in Northeast Asia, covering roughly 1,257 kilometres and clocking in at just under two hours in the air. Six carriers serve the pairing — Korean Air and Asiana on the South Korean side, ANA and budget-friendly Eastar Jet from Japan, plus Delta and United operating it primarily as a connecting feed for their transpacific networks — with narrowbodies like the Boeing 737 and Airbus A321 doing most of the work. A practical note worth knowing: South Korea lifted its visa-on-arrival restrictions for Japanese passport holders long ago, but travellers on other passports should confirm K-ETA requirements before booking, as enforcement at ICN is consistent. On the fare side, midweek departures in January and February tend to yield the lowest economy fares, while Korean Air's Prestige Class seats are often bookable at relatively reasonable award rates during the same off-peak window.
