You cannot change the period of validity after collecting or purchasing a pass.
To make changes to a pass purchased on the JR-EAST Train Reservation website before collecting it, please see the User Guide.
A refund can only be provided within the period of validity of your pass and before you have started using it. To obtain a refund, you must apply at a JR EAST PASS (Tohoku area) collection/sales point (not available at some collection/sales points).
If a seat ticket is issued and you are late for the indicated train's departure, no refund will be issued, even if the ticket has not been used.
Please note that ticket sales at reserved seat ticket vending machines with passport readers may be available for more hours of the day than at ticket sales counters (at JR EAST Travel Service Center, etc.). For inquiries regarding refunds, please contact a ticket sales counter (at JR EAST Travel Service Center, etc.) during business hours.
To obtain a refund for passes purchased on the JR-EAST Train Reservation website before collecting them, please see the User Guide.
