Sit on the Right side of the plane for the best views on flights from Tokyo to Seoul. Right side wins at both ends of the flight. During the cruise over the Yellow Sea the views are largely open water on both sides, but the right side gives slightly better angles on the Korean coastline during descent and the Tokyo Bay panorama on departure.

During takeoff from Tokyo International (HND), sit on the Right side for the best views. HND typically departs northwest on Runway 34L/34R toward the city, and a right-side seat gives you a clear view back over Tokyo Bay and the dense urban grid of central Tokyo including the waterfront reclamation islands. You also get a good look at the Yokohama skyline to the south before the aircraft turns west. Notable sights include: Tokyo Bay, Odaiba waterfront district, Yokohama port and bay bridge, Tokyo waterfront reclamation islands.

When landing at Incheon International (ICN), sit on the Right side for the best views. ICN approaches typically come in from the east or southeast over the Yellow Sea, and a right-side seat gives you the view over the Han River estuary and the western coast of the Korean peninsula as you descend. You can clearly see the tidal flats and islands of the Gyeonggi Bay area, which are visually striking from altitude. Notable sights include: Han River estuary, Gyeonggi Bay tidal flats and islands, Incheon coastal reclamation areas, Ganghwa Island.

The flight from Tokyo International (HND) to Incheon International (ICN) takes Approximately 2 hours 15 minutes.

The flight crosses the Tsushima Strait between Japan and Korea, passing near Tsushima Island (a long narrow island clearly visible from altitude), then over the open Yellow Sea. The Korean island of Jeju-do may be visible to the south depending on routing. The route largely avoids major mountain ranges, staying over water for the majority of the flight.
