When traveling from Tokyo to Osaka (or Kyoto) on the Tokaido Shinkansen in 2026, you should sit on the right-hand side of the train to see Mount Fuji. Specifically, you should request Seat E in a standard 3-2 seating arrangement. Mount Fuji will appear roughly 40 to 45 minutes after leaving Tokyo Station, shortly after the train passes Mishima Station. The best view occurs just before and after the train passes through Shin-Fuji Station. If you are traveling the opposite way, from Osaka back to Tokyo, you should sit on the left-hand side (Seat A). In 2026, travelers are advised to check the "Fuji visibility forecast" on the morning of their trip, as the mountain is often shrouded in clouds during the summer months. Winter and early spring provide the clearest views of the snow-capped peak, making that right-side window seat one of the most coveted "views" in the world of rail travel.
