Good day,
I would be arriving to Japan on August 4, 2013 via Kansai Airport in the late evening. Assuming I could activate a Japan Rail Pass around 10PM, would I be able to reserve a nobi-nobi seat for the Sunrise Seto overnight train going to Tokyo no problems? My concern would be the train is already fully reserved by then, and I'll have no other options.
Also, would I be able to reserve from the station at Kansai Airport or it needs to be at Osaka Station?
Thanks.
