Can I extend my Japan Rail Pass?
A Japan Rail Pass cannot be extended so make sure to choose wisely. This applies to both your Exchange Order Note’s 3 month validity from date of issue and the time period (7, 14 or 21 days) of the Japan Rail Pass itself. One option is to purchase multiple Japan Rail Passes and to only validate each one just before the period of travel in which you wish to use it.
