Sit on the Right side of the plane for the best views on flights from Kuala Lumpur to Tokyo. The right side wins overall primarily for the spectacular KL departure view of the Petronas Towers and Klang Valley. During the cruise over the South China Sea and East China Sea the views are largely open water on both sides, so the departure experience tips the balance. The landing advantage on the left is real but modest — Tokyo Bay is impressive but the approach is over flat terrain.

During takeoff from Kuala Lumpur International (KUL), sit on the Right side for the best views. KLIA's runways are oriented roughly north-south. Departing northbound toward Japan, the right (east) side gives you a clear view over the Klang Valley toward Kuala Lumpur city center, with the Petronas Towers and KL Tower visible as you climb out. The left side faces west toward the Strait of Malacca and flat palm oil plantation terrain. Notable sights include: Petronas Twin Towers and KL city skyline to the northeast, Titiwangsa Mountain Range on the eastern horizon, Klang Valley urban sprawl, Putrajaya government district directly below or slightly south.

When landing at New Tokyo International (NRT), sit on the Left side for the best views. NRT's primary runways (16R/34L and 16L/34R) are oriented roughly north-south. Arriving from the southwest on a southeasterly heading to land on runway 34, the left (east) side looks out over the Pacific coastline of Chiba Prefecture and Tokyo Bay, while the right side faces inland. On the more common runway 16 approach heading south, the left side still captures Tokyo Bay and the city's eastern waterfront. Notable sights include: Tokyo Bay and its reclaimed land districts, Chiba city and port along the western bay shore, the broad flat Kanto Plain stretching inland, Tokyo's urban density visible to the west across the bay.

The flight from Kuala Lumpur International (KUL) to New Tokyo International (NRT) takes Approximately 6 hours 30 minutes to 7 hours.

The route tracks northeast over the South China Sea, passing east of Vietnam's coastline and the Gulf of Tonkin, then crosses the southern tip of Taiwan or passes just east of it, before crossing the East China Sea toward Japan's Ryukyu island chain (Okinawa visible on clear days), then the Pacific coast of Kyushu and Honshu before descending into the Kanto region
