7 day pass valid from Monday to Sunday or from Monday to Monday?

Hi Corina,

It would be worth getting a JRPass if you can make your round trip in its 7-day of use. This works as follows, the pass is valid for 7 days of consecutive use and the first day is counted as a full day no matter the time that you start using it. So the pass will be valid until Sunday 23:59. It is perhaps better explained here.

It short: it would be worth getting a JR Pass if you could be back in Tokyo by Sunday evening. Otherwise I would suggest buying the tickets as you go.

I Hope this helps,
Daniel
