Hi, I am headed to Japan in December and will be travelling from Tokyo to Hiroshima, Kobe, Nara, Osaka and Kyoto.
I am planning for Hokkaido to be my final destination. Does anyone have suggestions as to how I can get from either Osaka or Kyoto to Hokkaido in the quickest time possible yet least expensive mode of transport?

Should I get the 14 days or the 7 days JR pass since I would be in Japan for 16 days? I am inclined to get the latter as I am thinking that I would be not be moving around that much in Hokkaido such that it would require me to get a JR Pass or might I be wrong, given that travelling to Hokkaido from Kyoto/Osaka would almost cost as much as the 7 days JR pass.

Any suggestions and advice would be greatly appreciated.
Thanks.
