Will I need to carry my passport around whilst using the activated pass? Or is just the pass alone sufficient for travel in Japan?
Also, I am planning on going from Osaka - Tokyo, I know the NOZOMI / MIZUHO are not available to JR pass holders, so I will be getting the Hikari from Shin-Osaka - should I be reserving seats on trains like this? I speak no japanese so will getting reservations be a problem w/ the language barrier?
