4 day flexible hokkaido rail pass

Hi there,

Here are the official rules for exchanging the JR Hokkaido 4-day Flex pass:

*The date of use cannot be selected with the Flexible 4-Day Ticket. It is effective the day you either purchase or exchange it, that being day one, and continues to be effective for ten days in which it can be used any four days either consecutive or not. EX: If you purchase or exchange a Flexible 4-Day ticket the 1st of July, it is effective until July 10th, and can be used any four days within the ten day period. *

Kind regards,
Daniel
