Sit on the Left side of the plane for the best views on flights from Tokyo to Kuala Lumpur. Right side wins at takeoff for Tokyo Bay views, but left side delivers the more sustained and geographically interesting experience: it picks up the South China Sea coastline of Vietnam and the Gulf of Thailand during cruise, and then the Titiwangsa Range on descent into KUL. The left side scenery during the middle and end of the flight outweighs the right side advantage at departure.

During takeoff from New Tokyo International (NRT), sit on the Right side for the best views. NRT typically departs on runways 16R/34L or 16L/34R. On a southbound departure heading toward KUL, aircraft climb out heading roughly south, then bank right (west) to track southwest. The right side picks up Tokyo Bay and the urban sprawl of greater Tokyo including the bay waterfront. Left side faces the Pacific Ocean with little to see. Notable sights include: Tokyo Bay, Chiba urban grid, Tokyo waterfront districts, Boso Peninsula coastline.

When landing at Kuala Lumpur International (KUL), sit on the Left side for the best views. KLIA typically uses runways 14L/32R and 14R/32L. Arrivals from the north generally approach from the northeast on a heading of roughly 140-150 degrees. The left side faces east toward the Titiwangsa mountain range running along the Peninsular Malaysia spine, which is clearly visible as a forested ridge. The right side looks west toward flat palm oil plantation terrain with little visual interest. Notable sights include: Titiwangsa Range (Main Range of Peninsular Malaysia), Gombak River valley, palm oil plantation patchwork, Putrajaya government district.

The flight from New Tokyo International (NRT) to Kuala Lumpur International (KUL) takes Approximately 7 hours.

The route tracks southwest over the East China Sea, crosses the southern tip of Taiwan or nearby, then passes over the South China Sea — a long overwater segment with occasional island groups including the Paracel Islands visible as tiny atolls. The Vietnamese coastline and Mekong Delta may be visible depending on exact routing. The flight crosses the Gulf of Thailand before making landfall over Peninsular Malaysia's east coast and crossing the Titiwangsa Range on descent.
