The "best" seat on a Shinkansen (bullet train) depends on your priorities: the view, luggage space, or tranquility. If you are traveling from Tokyo to Kyoto/Osaka, you absolutely want a Seat E in a standard car (or Seat D in a Green Car), as these are the window seats on the right side that provide a spectacular view of Mount Fuji about 40 minutes into the journey. If you are traveling with large suitcases, the best seats are in the last row of the carriage, which provides access to the "Oversized Baggage" storage area behind the seats (which must be reserved in advance in 2026). For the quietest experience, choose a car in the middle of the train to avoid the "wind noise" of the aerodynamic nose and the foot traffic of the smoking rooms or toilets. If you are a solo traveler, many people prefer the "2-seat" side of the 3-2 configuration to avoid being stuck in a middle seat, ensuring a more private and comfortable high-speed experience across the Japanese countryside.
