When traveling on the Shinkansen (Tokaido Line) from Tokyo to Kyoto in 2026, you should sit on the right-hand side of the train to see Mount Fuji. In the standard "Ordinary" cars, which have a 3-2 seating layout, the specific seat you want is Seat E (the window seat on the 2-seat side). In the "Green" (First Class) cars, which have a 2-2 layout, the window seat on the correct side is Seat D. About 40 to 45 minutes after leaving Tokyo Station, the train will pass through the Shizuoka area; on a clear day, Mount Fuji will be visible in all its glory for about 3 to 5 minutes near the Shin-Fuji station. If you are traveling in the opposite direction (Kyoto to Tokyo), you should sit on the left-hand side—again, Seat E or Seat D—as the train does not turn around, but merely reverses direction. Because these "Fuji-side" seats are the most popular and often sell out first, it is highly recommended to reserve them at least a few days in advance via the SmartEX app or at a JR ticket office to ensure you don't miss one of the most iconic views in Japan.
