Yes, you can stand on the Shinkansen (bullet train) in Japan, but it is generally restricted to specific cars. On most 2026 Shinkansen lines, there are Non-Reserved (Jiyu-seki) cars where passengers who do not have a seat assignment are permitted to stand in the aisles or the vestibule areas between cars if the train is full. However, standing is strictly prohibited in Reserved (Shitei-seki) cars and Green Cars (First Class) to maintain the comfort and premium environment of those sections. If you are using a Japan Rail Pass or a standard ticket during peak travel seasons like Golden Week or New Year’s, you may find yourself standing for the duration of a high-speed journey if you haven't booked a seat in advance. Safety-wise, the Shinkansen is incredibly stable even at 320 km/h, but passengers are advised to hold onto the recessed handles on the corners of the seats if they are standing while the train is in motion or decelerating into a station.
