Sit on the Left side of the plane for the best views on flights from Toulouse to Tokyo. Left side wins at both ends of the flight — the Pyrenees on departure and Tokyo Bay plus the city skyline on arrival. During the cruise over Central Asia and China, the left side also tends to face slightly more toward notable terrain including parts of the Tibetan Plateau's northern edge depending on exact routing.

During takeoff from Blagnac (TLS), sit on the Left side for the best views. Toulouse-Blagnac typically departs eastward on runway 32L/14R or uses runway 14 heading southeast. A left-side seat gives you a clear view south toward the Pyrenees as you climb out, with the snow-capped ridge visible on clear days. The city of Toulouse and the Garonne river are also briefly visible below. Notable sights include: Pyrenees mountain range to the south, Garonne river snaking through Toulouse, Canal du Midi corridor heading east, Toulouse city center and its terracotta rooftops.

When landing at Tokyo International (HND), sit on the Left side for the best views. HND runway 34L/34R approaches come in from the south over Tokyo Bay, and a left-side seat gives you the best view of the Tokyo skyline, including the distinctive Tokyo Tower and the urban density of central Tokyo, as you descend over the bay. The right side faces mostly open water and the Yokohama waterfront. Notable sights include: Tokyo Bay and its reclaimed land, central Tokyo skyline with Tokyo Tower, Rainbow Bridge and Odaiba waterfront, Yokohama port and bay to the southwest.

The flight from Blagnac (TLS) to Tokyo International (HND) takes Approximately 13 to 14 hours (no direct service exists; this would be a routing via a hub, but a hypothetical direct great-circle flight would be roughly 13.5 hours).

The great-circle route from Toulouse to Tokyo passes over the Alps near the Italian border, then across northern Italy or Austria, continuing over Ukraine or southern Russia, then across Kazakhstan and the southern Siberian steppe, skirting north of the Tibetan Plateau, crossing northern China over Inner Mongolia and the Gobi Desert margins, then descending over the Korean Peninsula or Yellow Sea before crossing into Japanese airspace over Kyushu or the Kii Peninsula
