"Upside-down Fuji" is a natural phenomenon where an inverted image of Mount Fuji is reflected on the calm surface of a lake or rice paddy. It has long been cherished as a mystical and spectacular sight that appears only when there is no wind or waves (a "nagi" state) and clear skies.
There are many famous spots around Mount Fuji where you can capture beautiful upside-down Fuji reflections on the water.
