Flights from Seoul to Tokyo
The 1,180-kilometre hop between Seoul's Gimpo and Tokyo's Haneda is one of Northeast Asia's busiest short-haul corridors, completing in a typical block time of around one hour fifty minutes and benefiting from both airports' unusually central positions within their respective cities. Korean Air, Asiana Airlines, and All Nippon Airways share the route and generally operate narrowbody jets — typically the Boeing 737 or Airbus A320 family — though Korean Air occasionally rotates wider equipment during peak periods. The most practical note for first-timers is the time-zone arithmetic: Seoul runs one hour ahead of Tokyo, so a late-morning departure from Gimpo can land at Haneda before noon local time, leaving a full working or sightseeing day intact. Fare-wise, mid-week departures and travel in late January or September tend to offer the most competitive economy pricing, while business-class award availability on both Korean carriers is often strongest when booked well outside school-holiday windows.
