Sit on the Right side of the plane for the best views on flights from Tokyo to Seattle. The right side wins overall because the Haneda departure delivers the most dramatic single moment of the flight — Tokyo Bay, the city, and Mount Fuji simultaneously — which outweighs the left-side advantage on landing at BFI. Over the Pacific and Alaska the views are largely symmetric cloud and ocean, so departure scenery is the deciding factor.

During takeoff from Tokyo International (HND), sit on the Right side for the best views. HND typically departs northeast or east over Tokyo Bay on runways 34L/34R or 05. A right-side seat gives you the sweep of Tokyo Bay, the city grid of central Tokyo, and on clear days Mount Fuji rising to the southwest as you bank north. Left side faces mostly industrial waterfront and reclaimed land. Notable sights include: Tokyo Bay, Mount Fuji (southwest, distant), Yokohama port and bay bridge, central Tokyo skyline including Shinjuku towers.

When landing at Boeing Fld King Co International (BFI), sit on the Left side for the best views. BFI sits just south of downtown Seattle, and aircraft typically approach from the north or south over Puget Sound on runway 13L/13R or 31. A left-side seat on approach from the north gives you Elliott Bay, the Seattle downtown skyline, and the Olympic Mountains across the water to the west. Right side faces the Cascade foothills and industrial south Seattle. Notable sights include: Elliott Bay and Puget Sound, Seattle downtown skyline, Olympic Mountains (west, across the sound), Mount Rainier (southeast, distant).

The flight from Tokyo International (HND) to Boeing Fld King Co International (BFI) takes Approximately 9 to 10 hours.

The great circle route from Tokyo to Seattle arcs northeast over the North Pacific, passing south of the Kuril Islands and Kamchatka Peninsula, then across the Gulf of Alaska. On clear days you may see the Aleutian Island chain as a distant broken arc, and the snow-covered peaks of the Alaska Range and Coast Mountains of British Columbia become visible in the final two hours of flight as the route descends toward the Pacific Northwest.
