Our tour guide, Xiao Sun, was witty and insightful, always attentive to the group's needs. No need to worry about who would take photos for you—the guide was right there beside you! We had the whole place to ourselves while playing in the snow early in the morning, with no other tourists around—it was wonderful! Lake Shikotsu was beautiful, but the icefall festival was rather ordinary. Winter is a great time to visit various parts of Hokkaido; I highly recommend this trip, and I'd definitely go again next time!
The tour guide was extremely attentive, the attractions were attractive, three meals were included, and the hot spring hotel was comfortable.
