Mr. Wei, our driver in Hokkaido, is incredibly warm and hospitable. He told us the best spots for taking photos and whether a particular attraction was suitable for us. He answered all our questions without hesitation, and he was especially considerate of our elderly family members. He helped us with anything we needed and recommended many delicious Hokkaido dishes. He also took us to some smaller attractions in our chartered car. It was a perfect experience!
