delay to use it the pass

Hi there!

This is always a bit of a confusing point. Keeping it simple, you can exchange (activate) the JR Pass up to 90 days after purchase.

At the moment of exchange you can select a date for later use up to 30 days a head of time.

You could thus start using the JR Pass up to 120 days after purchase if you activate it on the 90th day.
