[Reservations within one month]: You can change your boarding date within the above period as many times as you wish, however you can only make reservations for trains up to one month in advance of the change date. Example) If you make a reservation on July 1 for a train on July 15, you can change the date of your reservation as many times as you wish as long as it is by October 14. However, for example, if you change your reservation on July 10, you can only make reservations for trains up to August 10, one month ahead of the reserved date. 2.

Example) If you made a reservation on July 1, 2023 for a train to be boarded on July 1, 2024, you can change the reservation as many times as you wish as long as the boarding date is no later than September 30, 2024. However, for example, if you make a change on July 10, 2023, you can only make reservations for trains up to July 10, 2024, which is one year ahead.
(Hayatoku fares)	For changes to a train with a boarding date that is at least 3 days on*1 from the point in time the reservation is changed, if such changes satisfy the established terms and conditions of the Hayatoku fare and seats are available, changes are allowed for the same Hayatoku fare. When making a change, you can also change for another fare that is available for purchase (you will need to make up any difference in price). When changing to a train with a boarding date that falls within 2 days*2 of the point in time the reservation is changed, you will need to change to a different fare such as "smartEX" etc., and make up any difference in price. At least 21 days on for "EX Hayatoku 21" Within 20 days for "EX Hayatoku 21"

*1 If you are tranferring and using 2 trains or more, you can make changes up to the departure time of the first train on which you have a reserved seat.

*2 As a rule, each time a change is made we take a new payment for the post-change fare, and then refund the cost of the pre-change fare. As a result, there may be times when your credit card limit, or similar, will not allow the changes to be made. Note that the payment is settled in YEN and foreign transaction fee etc. accompanying this shall be governed by a contract between the Member and his or her credit card company.

• If there are no empty seats in the train you want, then you will not be able to make a change. If we are unable to complete your application for change due to all seats being full etc., then we will keep your reservation with the details held before the change was requested.
• If you are reducing the number of passengers with reservations, please process this through the "Changes" function (you will need to pay a refund charge for the number of passengers cut).

Members are not able to process changes themselves once they have picked up tickets or gone through a ticket gate using QR-Ticket or an IC card.

• If, after picking up your tickets, you want to change either the boarding date, boarding sections, type of train or facilities, please apply at a ticket booth in any main JR Central, JR West or JR Kyushu station before the time your train is scheduled to depart and then purchase new, normal tickets (i.e. non-discounted) as required. In this case, the ticket booth at the JR Central, JR West or JR Kyushu main station will issue a refund for the tickets you hold to the credit card you used to pay for this Service with no refund charges payable.
• If you decide to change your train once you have passed through the ticket gate using QR-Ticket or an IC card, please speak to a member of the station staff at the gate. We will arrange it so that members can again process the changes themselves. However, this must be done before the scheduled time of departure of the reserved train.

• Provided that it is prior to the departure time of the reserved train and that the train you want to change to is the same as the original reservation in terms of date, boarding section, facilities and train type (you cannot change a Nozomi or Mizuho service for Hikari, Kodama, Sakura or Tsubame; or vice versa) then we will accept the change of train with no charge payable for the first change only at ticket vending machines and ticket booths at any main JR Central, JR West or JR Kyushu Shinkansen station (note that this excludes Hayatoku fares where passengers can only travel on the trains specified).

• Please speak to the "Tokaido Sanyo Kyushu Shinkansen Internet Reservation Service Customer Center" if you cannot use the membership feature to process changes/refunds etc., for certain boarding sections only.
