Seiwa Kogen Astronomical Observatory - Seiwa Kogen No Yado

It is inaccessible without a car, but on the flip side, there is almost no artificial light around and you can see a starry sky after 10pm. It depends on the weather, but that alone makes it worth staying here. The accommodation is a lodge style and you can cook simple meals yourself, but you will need to bring your own cooking utensils. You can also have yakiniku for dinner, and simple breakfasts such as bread and soup are distributed the night before. The rooms are well cleaned, but there is a high chance of encountering insects in the summer. When I stayed there, a small centipede made an appearance.
