We met at 8:00 AM sharp and departed on time. Hanna, our tour guide, provided excellent commentary throughout the journey; the driver drove very smoothly, and the schedule was well-planned. The snow scenery was absolutely gorgeous! Highly recommended for anyone wanting to see Hokkaido's beauty.
This time, I chose the large public bath at Mansikaku. It wasn't crowded on a weekday, so soaking in the water was incredibly relaxing. The changing area was also very clean and bright. From the open-air pool, you could see the autumn-colored mountains through the fence.
