Sit on the Left side of the plane for the best views on flights from Singapore to Tokyo. Left wins at both ends of the flight. During the cruise over the South China Sea and East China Sea the views are largely oceanic on both sides, but the left side also picks up the coastlines of Vietnam and southern China in the middle portion of the flight, giving it a slight edge throughout.

During takeoff from Singapore Changi (SIN), sit on the Left side for the best views. Changi typically departs on runway 02L/02R heading north, so the left (west) side gives you views over central Singapore — the downtown skyline, Marina Bay, and the reservoir system inland. The right side faces east toward open sea almost immediately. Notable sights include: Marina Bay Sands and CBD skyline, MacRitchie Reservoir, Johor Strait and southern Malaysia coastline, Sentosa Island.

When landing at Tokyo International (HND), sit on the Left side for the best views. Haneda's primary arrival from the south typically uses runways 34L/34R, approaching from Tokyo Bay on a northward heading. The left (west) side looks directly over central Tokyo — Shibuya, Shinjuku, and on clear days Mount Fuji to the southwest. The right side faces east over Tokyo Bay and suburban Chiba. Notable sights include: Mount Fuji (southwest, clear days), Shinjuku and central Tokyo skyline, Tokyo Bay, Rainbow Bridge and Odaiba.

The flight from Singapore Changi (SIN) to Tokyo International (HND) takes Approximately 6 hours 30 minutes to 7 hours.

South China Sea (broad open ocean for the first two hours), Vietnamese coastline near Da Nang and Hue visible to the west, the Pearl River Delta and Hong Kong area passing to the left around the midpoint, Taiwan Strait and then the island of Taiwan itself, East China Sea, Ryukyu Islands chain (Okinawa visible as a distinct island), and the southern Japanese island of Kyushu before crossing into Honshu
