Diamond Fuji

Brief moment when the sun aligns precisely with Mt. Fuji's summit, creating the illusion of a glowing jewel atop the peak. Lake Yamanakako to the northeast offers evening viewings from mid-October through late February, with spots like Hirano lakeside and Nagaike Water Park drawing dedicated photographers. On calm days, a still lake surface produces a doubled reflection known as the double diamond. For the morning version, Lake Motosuko to the west is the go-to location. On New Year's Day, the diamond emerges at roughly 7:40 a.m. from the observatory below Mt. Ryugatake.
