Consider flying. If you buy the domestic flight in combination with your international flight, it might be just as cheap as the train ride, if not cheaper. And much faster!

You have to catch a train into Tokyo first (about one hour) and catch a train from there in direction of Sapporo.

You should just fly into Sapporo. It would save you time and money.

I'm going on the 3rd august and considered taking a train between Tokyo and Sapporo, but when I looked at the prices, the flight seemed more worth it (around ��60 for flight, ��70 for train) and also the JR pass does not fully cover that journey (I think). Also flying is a lot quicker as the train takes nearly a day to get there.
