This time we spent the night in the car at Jododaira in Bandai-Asahi National Park.
This national park is a place of natural beauty that straddles three prefectures: Yamagata, Niigata, and Fukushima.
Volcanic gas is very toxic, so you need to be careful, but the danger level is 1, so you can stay in your car here.
If the weather was good, it would be crowded with climbers starting early in the morning and people spending the night in their cars doing stargazing, but unfortunately the weather was bad that day.
I ended up spending the night alone in my car on top of a mountain at an altitude of 1600m.
