If your Shinkansen (Japanese bullet train) is cancelled due to weather, technical issues, or significant delays, the JR (Japan Railways) refund policy is very robust and passenger-friendly. If the train is cancelled or delayed by more than two hours, you are entitled to a full refund of the "Limited Express" (Surcharge) portion of your ticket, even if you still complete the journey on a later train. If you decide not to travel at all because of the cancellation, you can get a full refund of the entire ticket (both the base fare and the surcharge) at any JR ticket office (Midori-no-Madoguchi) with no handling fee. In 2026, if you booked through the Smart EX or Ekinet apps, you can often process these refunds or change your reservation to the next available train directly on your smartphone at no extra cost. If the cancellation happens while you are at the station, staff will usually guide you to the non-reserved cars of the next departing train. For those using a JR Pass, you cannot get a "refund" for a specific day, but you can simply go to the ticket counter and have them issue you a new reserved seat for a later train for free.
