I'll be there on 5th morning, currently don't know my itinerary yet, my planners still deciding the route, currently they say Tokyo + Sapporo, wanna join us for a trip? Hee.
Hmm some things I heard about Hokkaido, Snow can accumulate to 1 foot on an average day. 2 feet ot more in slightly colder times. and frostbites are common. You should visit there either now or last month.
