I traveled to Nagano prefecture with my son on a summer vacation. In August, Mie Prefecture had a day of 32 degrees Celsius or higher, but the Kirigamine campsite at an altitude of 1610m was 21 degrees Celsius even in the daytime. It was quite cold at night. The origin of the name Kirigamine is that fog often occurs. This day was also covered in fog in the morning. However, from noon, it was sunny and I could see a beautiful sight.
