JRPass

thanks mari but isn't there a sleeper that travels from tokyo to sapporo what's wrong with this, can the jrpass be used for this train?
if its better the other way what is a good town to use as a halfway point to maybe catch the shinkansen in the morning to then spent the day there then catch the next train the next morning although i would perfer a sleeper from tokyo to sapporo.
thankyou for your help..

thanks again i'm in Japan for 3 weeks. seeing Tokyo, Sapporo & Niseko, 2 nights were going to be on the train but that does not seem to be working out so the idea that i have 2 nights free, my thought is i can either extend where i'm staying but i have to catch 2 trains 1 that is 3 to 4 hours & the other 4 to 5 hours why not just catch the first 1 early in the morning get off & see somewhere else in Japan then catch the next train the next morning. so if anybody has any ideas of stuff to see around Aomori or a town or city close by this would be helpful.. THANKYOU

the only other question i have is do i have to book these trains

Hey Mari Thankyou for your help so far
. I have worked out what i am going to, do from Tokyo i am going to catch a Shinkansen Hayate to Shin-Aomori first thing in the mourning then from Shin-Aomori to Hakodate i will catch a LTD.EXP.Super Hakucho.. Then have a nice day in Hakodate. The next mourning i will catch a LTD.EXP.Super Hokuto from Hakodate to Sapporo.. on the way back i will do the same in reverse

My questions are
will the railpass cover all of this?
does any of this need to be booked? (i will not need the sleeper)
what does carpeted mean is this seated?
i will have my wife & 2 kids with me do i need to know anything i might of missed with this?
thankyou once again for your help.. :)

thanks mari
went to Japan in Feb2013 & had a great time the railpass was a great idea & i was able to book all of these trains using the railpass. the Japanese people were always happy,friendly & super helpful it was such a beautiful place to visit for me & my family everybody had such a great time...

tips.. use Hyperdia to work out the trains you wish to catch

     book these trains as soon as you get to Japan
     the railpass does not work on non JR trains (mostly subways)
     Japanese people will help so if you dont speak Japanese ask simple straight forward questions
