Visiting several attractions in one day that are impossible to do solely by public transportation offers excellent value. It's a great option if you want to enrich your trip beyond city shopping and historical sites! * However, the time allotted at each attraction could be adjusted: Based on this experience, the Showa Shinzan itinerary could be removed, and the time spent at Lake Toya and the Meisui Park could be extended. Lake Toya included lunch, but the area to view was vast; allocating only 1.5 hours was too rushed, leaving only a short walk along the lake and no time to even visit the onsen town shops—I suggest extending the time at Lake Toya to 2 hours. The itinerary title listed "Yotei-yama Meisui Park," which might raise expectations of seeing Mount Yotei itself… but in reality, you only glimpse the mountain through the car window, and the only actual visit is to "Kyogoku-cho Izumi Park," leading to a disappointment. I suggest renaming it or expanding the areas visited.
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!
