Your Exchange Order is not your Japan Rail Pass and must be submitted at an Exchange Office in Japan, along with your passport stating your ‘Temporary Visitor’ status to receive your pass.
How long do I have until my Exchange Order expires?
An Exchange Order is valid for 3 months from the date it is issued. You must turn in your Exchange Order within this time to receive your Japan Rail Pass.
Do I have to use my JR Pass as soon as I receive it?
No, you can specify what day you wish your pass to begin when you turn in your Exchange Order. The start date must be within 1 month from the the date the JR Pass is received. Once the pass has a start date written on it, it cannot be changed.
Please see here for further information on activating your Japan Rail Pass.
