If you miss your Shinkansen (bullet train) in Japan, the outcome depends on the type of ticket you purchased. For those with a Reserved Seat ticket, you don't necessarily need to buy a brand-new one; you are permitted to board the non-reserved (Jiyu-seki) section of any subsequent Shinkansen of the same category (e.g., another Nozomi or Hikari) on the same day. However, you forfeit your right to a specific seat and must find an open one in the designated unreserved carriages (usually cars 1–3). If you insist on having a reserved seat for the next train, you will typically need to pay the "Limited Express" reserved seat surcharge again. If you have a Non-Reserved ticket, you can simply hop on the next available train without any penalty. For premium classes like Green Car or Gran Class, missing your train generally means you lose the seat and the upgrade fee unless you change the ticket at a ticket office (Midori no Madoguchi) before the original train's departure.
