A family of five (two adults and three children aged 5, 3, and 0) set off on a 10-day motorhome journey through Nagano Prefecture in August to escape the heat. The route includes Karuizawa, Kusatsu, Lake Shirakaba, Hakuba, Azumino, and the Kiso Valley. The family plans to stay in hotels every 4–5 days for rest and laundry. The trip began before the peak holiday season to avoid crowds.
