Hi,
I'm going to Japan in 2 weeks, but this time I'm going to stay several days in Osaka, Kyoto and Tokyo separately for more than 1 week (it's beneficial to me to buy 1 week pass). The time between my journey from Tokyo-Osaka and Kyoto-Tokyo is roughly 10 days. I've read somewhere that you could have a 4 days pass in the past, possibly not anymore?
The other question is, to buy individual train journeys from Tokyo - Osaka and Kyoto - Tokyo should I buy those train tickets now or I can buy those on the day of the journey?
Many thanks,
David
