I will arrive Japan on 26 Dec 13 with my family 6 person (1 infant.)
I will change JR rail pass on 28 Dec 13.
Can I reserve seat at Shinkansen from Osaka to Tokyo on 30 Dec 13 , and Tokyo to Osaka on 2 Jan 14?
I afraid I can reserve seat on long new year holiday or not.
Which way is better to go from Osaka to Tokyo on that public holiday?
Or I should ask my friend at Japan to reserve Shinkansen seat at the station.
