Despite the bad weather, we were still able to appreciate the beauty of Hokkaido on this trip. The free foot bath at Jozankei warmed us on a chilly day; the clear waters of Lake Toya brought us a sense of tranquility; and while drinking sweet spring water at Meisui Park, we were surprised to be caught in a hailstorm. Our guide, Mr. Hu, provided excellent service; thank you for your assistance on this trip.
Our guide this time was Xiao Hong, who was very kind and attentive, introducing us to the history of Hokkaido, various attractions, local cuisine, must-buy items, and more. He was always ready to help if we needed anything. I highly recommend that you go snowmobiling at your own expense; it's a truly unique experience.
Seeing Hell Valley in person was breathtaking and incredibly beautiful, and we even saw wild deer. It was a pity we encountered heavy rain at Lake Toya, otherwise we could have stayed longer to take photos. The scenery along the Otaru Canal was also stunning. Thank you to the kind and welcoming Rita for taking care of all the travelers and answering our inquiries. Hope to have the opportunity to come again! ☺️
