"Pearl Fuji," a phenomenon in which a full moon appears to be resting atop Mt. Fuji, is observed from Mt. Ohira in Yamanakako, Yamanashi Prefecture, on early Friday morning.
Because the full moon resembles a pearl, the phenomenon is called "Pearl Fuji," in contrast to Diamond Fuji, a phenomenon in which the sun sets behind the summit of Mt. Fuji, appearing like a shimmering diamond.
"Pearl Fuji" can be observed only in a cloud-free sky around the time of a full moon.
