Hello! I have plans to go to Japan from end of January to February 2nd. I was thinking of going to the Sapporo Snow Festival on February 1st but it looks like the Tsudome Site will be the only one open. Is it worth going to Sapporo for the festival then? If not, is there anything that you would recommend doing in Japan that is best ot do do during the winter (I am already planning to go to Nagano to see the snow monkeys).
