Sit on the Left side of the plane for the best views on flights from Osaka to Seoul. While takeoff favors the right for Osaka Bay views, the landing approach over Seoul and the Han River is more visually rewarding and geographically significant. Left-side seats capture the descent into Korea's most densely populated region with distinctive river and urban geography.

During takeoff from Osaka International (ITM), sit on the Right side for the best views. ITM typically departs to the south or southwest (Runway 32L/32R). Right-side seats face toward Osaka Bay and the Kobe-Osaka metropolitan area during initial climb, offering clear views of urban sprawl and water features. Left side faces inland terrain with less distinctive visual interest during departure. Notable sights include: Osaka Bay (immediate south), Kobe city district (southwest across the bay), Awaji Island (south-southeast in the bay), Rokko Mountains (distant northwest).

When landing at Incheon International (ICN), sit on the Left side for the best views. ICN uses Runways 15L/15R or 33L/33R depending on wind. Typical westerly approaches (Runway 15) bring aircraft over the Yellow Sea from the west, then descend across Incheon's western districts and reclaimed land. Left-side seats face north toward Seoul and the Han River valley during descent, providing views of Korea's most populated region and distinctive geography. Notable sights include: Han River (visible as a winding waterway north of ICN), Seoul metropolitan area (north, sprawling across hills), Incheon's reclaimed land zones (immediate south and west of runway), Yellow Sea (western approach).

The flight from Osaka International (ITM) to Incheon International (ICN) takes Approximately 2 hours.

The flight crosses the Korea Strait (Tsushima Strait) at roughly the midpoint. At cruise altitude (around 30,000 feet), the strait appears as open water with minimal visible detail. The Japanese island of Tsushima lies to the west of the direct route but is typically too far left to see clearly. The Korean peninsula's southern coast (Jeolla Province) becomes visible on approach to ICN, showing a rugged, island-dotted coastline before ascending terrain inland.
