Sit on the Left side of the plane for the best views on flights from Tokyo to Kathmandu. Left side wins both ends of the flight. During the cruise over the Tibetan Plateau, the left side also faces south toward the main Himalayan chain, offering periodic views of high peaks including Everest from cruising altitude on the approach to Nepal. Right side has little to offer over the open Bay of Bengal and flat Gangetic Plain.

During takeoff from New Tokyo International (NRT), sit on the Left side for the best views. NRT typically departs westbound on runway 16R/34L or 16L/34R. On a westbound departure toward Nepal, a left-side seat gives you views over Tokyo Bay and the sprawling Tokyo metropolitan area as the aircraft turns west. You can clearly see the bay's geometry and the dense urban grid of greater Tokyo spreading inland. Notable sights include: Tokyo Bay, Tokyo metropolitan grid, Chiba coastal lowlands, Boso Peninsula coastline.

When landing at Tribhuvan International (KTM), sit on the Left side for the best views. Tribhuvan International typically uses runway 02/20. Arrivals from the east on runway 02 approach from the south, meaning a left-side seat faces east toward the Himalayan wall including Everest, Lhotse, and Makalu on the horizon as you descend into the Kathmandu Valley. This is one of the most dramatic approach views in commercial aviation. Notable sights include: Mount Everest and Lhotse massif on the distant horizon, Makalu, Kathmandu Valley bowl, Bagmati River winding through the valley floor.

The flight from New Tokyo International (NRT) to Tribhuvan International (KTM) takes Approximately 7 to 7.5 hours.

The route tracks southwest over central China, crossing the Yangtze River basin and Sichuan Basin before climbing over the eastern Tibetan Plateau at around 14,000 to 16,000 feet terrain elevation. The aircraft then crosses the main Himalayan chain before descending into Nepal. The Tibetan Plateau appears as a vast high-altitude brown and ochre landscape with braided river valleys. The Bay of Bengal is crossed briefly in the southern portion of the route before the final approach into Kathmandu.
