I will be in Sapporo for 5 days over Christmas.
I would like to do skiing for one day. There is different ski resorts around Sapporo but which one is the most convenient with other activities like spa?

Moreover, I would like to invite my friend to a nice japanese restaurant on Dec24. Do you have any recommendations? I do not mind if it is ramen, shabu, etc.

Any other tips?

Thanks in advance!
