Missed your Smart EX Shinkansen? Check whether you booked a Hayatoku fare
Before boarding another Shinkansen after missing your booking, open the reservation and read the fare name. Hayatoku fares have different missed-train rules from eligible standard Smart EX bookings.
This guide concerns Smart EX on the Tokaido, Sanyo and Kyushu Shinkansen. It does not apply automatically to another booking service, a package holiday or every Shinkansen line.
If the original train hasn't left yet
Stop somewhere safe and open your reservation. The official FAQ allows a change to a non-Hayatoku product before the original train's departure, before gate entry and before collecting paper tickets, with travel within three months of the initial purchase. Pay any difference in price shown for the change.
Opening the change screen is not the same as completing the change. Make sure the new train and departure time appear in the confirmed booking before relying on them.
Already through the gate, holding collected tickets or unable to change online? Show station staff the booking and any tickets before buying something else. They need to know which steps you've already completed.
After departure, the fare matters
| Booking | Smart EX's missed-train guidance |
|---|---|
| Eligible products other than Hayatoku | Travel in a non-reserved ordinary-car seat on a later train that day covering the same booked section |
| Hayatoku | Valid for the booked train and facilities; not automatically usable on a later train, even in a non-reserved seat |
A reserved seat on the original train does not provide another reserved seat on the later one. Using the missed-train provision and obtaining a new seat reservation are different matters.
For Hayatoku, additional ticket purchases and normal charges can be required. Don't assume that a previous experience of boarding a later train applies to the fare you bought this time. Look for Hayatoku in the confirmation before asking staff what to do.
Not every later train has a non-reserved car
Check that the train stops at your destination and has the seating arrangement your ticket permits. During all-reserved operations, a train arriving at the platform is not simply a free-seating substitute.
Have four details ready for staff: fare name, travel date, stations and original train. Showing the reservation and saying “I missed this train. What can I use now?” gives the conversation a clear starting point.
Don't take an apparently empty reserved seat without arranging the right ticket. Someone may board later with a reservation for it.
If another train's delay caused the problem
Tell staff about the delayed service as well as the train you missed. Keep the booking and tickets available. Disruption-related arrangements need to be checked separately from an ordinary missed departure; don't decide on a refund or repurchase solely from the standard rule above.
For a future trip, reserved versus non-reserved seats is a useful starting point. When your departure time is uncertain, compare change conditions as well as the headline fare.
