Lake Saiko is counted as one of Mt. Fuji's five lakes and is the second smallest with an area of 2.12 sq. km and a circumference of 9.85 km. Because of its depth and the transparency of its water, it has a deep indigo color. Its surrounding has several different sightseeing spots. Apart from Saiko Iyashino Sato Nenba, where old Japanese houses stand next to one another, and walk-in onsen called Izumi no Yu, there are also caves including those from which cold wind blows. Furthermore, in winter, it is possible to see frozen tree columns and there are many ways to enjoy this spot.

Fuji, and the Aoikigahara Forest. Inside, there are about 20 stores and restaurants that offer local cultural experiences and serve specialty dishes.
Izumi no Yu, a Day-use Onsen
At Izumi no Yu, located near Lake Saiko, visitors can of course spend the night; however, it is also available as a walk-in onsen for use during the day.
