Sit on the Right side of the plane for the best views on flights from Helsinki to Tokyo. Right side wins at both ends of the flight. During the cruise over Russia and the Sea of Okhotsk, the right side also faces generally south, offering better views of the Kamchatka Peninsula's volcanic peaks as the route curves over the North Pacific. Left side has some merit over Siberia for Lake Baikal visibility depending on exact routing, but right side delivers more consistently across departure, key en-route features, and arrival.

During takeoff from Helsinki Malmi (HEM), sit on the Right side for the best views. Malmi's primary runway 18/36 means northbound departures climb out heading south, putting the Helsinki city center and harbor to the right (west). You get a clear view of the Helsinki peninsula, Senate Square area, and the islands of the inner archipelago spreading out below. Notable sights include: Helsinki city center peninsula, South Harbour and Market Square, Suomenlinna sea fortress islands, Helsinki archipelago inner islands.

When landing at Tokyo International (HND), sit on the Right side for the best views. Tokyo Haneda's primary international arrivals typically use runway 34L/34R on northerly approaches, or runway 16L on southerly approaches. On the common northerly approach over Tokyo Bay, the right side faces west toward the city, giving views of the Tokyo skyline, Tokyo Tower, and the dense urban sprawl of central Tokyo and Shibuya. Notable sights include: Tokyo Bay and its reclaimed land shoreline, Tokyo city skyline including Tokyo Tower, Yokohama port and bay waterfront, Kawasaki industrial waterfront.

The flight from Helsinki Malmi (HEM) to Tokyo International (HND) takes Approximately 9 to 10 hours.

The great circle route from Helsinki to Tokyo passes over St. Petersburg and the Gulf of Finland coast, then across western Russia and the Ural Mountains, continuing over central Siberia with the vast taiga and river systems of the Ob and Yenisei basins, skirting south of Lake Baikal depending on routing, crossing the Russian Far East over Yakutia, then descending toward the Sea of Okhotsk with the Kamchatka Peninsula and its volcanic chain visible to the south, before crossing the northern Japanese islands of Hokkaido and descending into the Kanto Plain toward Tokyo.
