Thank you to our tour guide, Guofeng, for leading the itinerary so professionally and clearly. Your explanations of the history and the itinerary's schedule were excellent, making our fourth day in Hokkaido a perfect success! 😊 And the weather was just as perfect throughout the trip! 👍🏻
Thank you, Director Huang, for your warm and detailed guidance. It was a wonderful trip! I was amazed by the vast natural landscape, breathed in the refreshing air, and felt completely at ease embracing nature.
We booked only the day before departure, and there was only a small group of five people on the day of the trip. Our guide, Jay, had to speak three languages! He was very talkative and provided very detailed explanations! Jigokudani (Hell Valley) and Lake Toya were both very beautiful, and the scenery along the way was fantastic!
