Flights from Seoul to Tokyo

One of Northeast Asia's busiest short-haul corridors, the roughly two-hour hop from Seoul Incheon to Tokyo Narita covers just over 1,250 kilometres and sits at the intersection of two of the region's most important aviation hubs. Korean Air and Asiana handle the bulk of local demand, typically deploying narrowbodies such as the Boeing 737 and Airbus A321, while Delta and United serve the route primarily as a connection bridge for their trans-Pacific networks, and All Nippon Airways adds solid frequency from the Japanese side. A practical note worth knowing: Narita sits roughly 60 kilometres from central Tokyo, so budget at least 90 minutes for the Narita Express or limousine bus onward — arriving into Haneda instead, when available, saves considerable time. Fares tend to soften in late January and February outside of the Lunar New Year window, and midweek departures often yield the most breathing room in economy.
