Diamond Fuji


SKY CIRCUS Sunshine60 Observatory


Please enjoy “Diamond Fuji,” which can only be seen a few days out of an entire year, from the SKY CIRCUS Sunshine60 Observatory.


What is “Diamond Fuji”?

It is named as such because of the phenomenon of light shining like a diamond when the sky rises from and sets into the peak of Mt. Fuji, at the moment when the sun and the mountain peak overlap perfectly.

It is an extremely rare sight that can be seen when the weather conditions are good.

From SKY CIRCUS Sunshine60 Observatory, which has no buildings around it to obscure one’s vision, as long as the weather conditions are right, it is possible to clearly see “Diamond Fuji” at the moment when the sun sets.
