Sit on the Left side of the plane for the best views on flights from Tokyo to Denver. The left side misses the best of the Tokyo departure but wins decisively on landing with the spectacular Front Range panorama. Across the Pacific cruise, neither side has a meaningful advantage over open ocean, but the Denver arrival on the left is one of the most dramatic mountain approaches in commercial aviation and tips the balance.

During takeoff from Tokyo International (HND), sit on the Right side for the best views. HND typically departs northeastward over Tokyo Bay on runway 34L/34R, and right-side seats get a clear view back over the bay and the Tokyo waterfront districts. You'll see the dense urban grid of central Tokyo spreading westward, and on clear days Mount Fuji appears to the southwest as the aircraft climbs and banks toward the Pacific. Notable sights include: Tokyo Bay, central Tokyo urban grid, Mount Fuji (southwest, on clear days), Yokohama port area.

When landing at Denver International (DEN), sit on the Left side for the best views. DEN typically lands from the east on runways 34L/34R or 35L/35R heading northwest, meaning left-side seats face southwest toward the Front Range of the Rockies. This gives a prolonged, unobstructed view of the entire Colorado Front Range including Pikes Peak, Longs Peak, and the Denver metro sprawl laid out against the mountains. Notable sights include: Colorado Front Range (Rocky Mountains), Pikes Peak, Longs Peak, Denver metro grid.

The flight from Tokyo International (HND) to Denver International (DEN) takes Approximately 10 to 11 hours.

The route tracks northeast over the North Pacific, crossing the Aleutian Island chain (Alaska), then arcing southeast over the Gulf of Alaska and coastal British Columbia. Passengers may glimpse the Alaska Range and Wrangell-St. Elias peaks on clear days over Alaska, followed by the Canadian Rockies in Alberta before descending over the Great Plains toward Denver.
