hello from Canada We will arrive monday May 13 and will go to Yokohama for a cruise Then we want to take the Shinkansen to go to OSAKA . There we will join a group from canada too to continue our trip in japan We need 4 tickets from SHIN YOKOHAMA to SHIN OSAKA.. I read that the NOZOMI is faster. We are 4 seniors with 1 luggage each of us. So we need to reserve place where we can put luggage as I read Is it better to reserve in advance or to buy at the station? If in advance , what the name of the web page ? How can I reserve with the luggage . Do you have any other suggestion We do not need the pass only one ticket each
