Diamond Fuji shines above Mount Fuji's peak: A rare sight awaits Tokyo on Sunday

The Japanese capital, Tokyo, is preparing for an extraordinary natural spectacle in which the setting sun transforms into a glittering diamond seemingly perched atop Mount Fuji, a phenomenon known as the “Diamond Fuji.”

The Tokyo Skytree administration announced on Sunday that the phenomenon is expected to be visible around 4:30 p.m. local time next Sunday from the observation decks at 350 and 450 meters above ground.

The phenomenon occurs when the setting sun aligns precisely with the mountain’s peak, making its rays appear like a gemstone illuminating the horizon.

This view from the tower is visible only twice a year, near the beginning of spring and winter according to the traditional Japanese calendar. The first opportunity this year was on February 3, making next Sunday the last expected occurrence until 2026.

However, witnessing the “diamond” is not guaranteed, as clouds and fog may completely obscure the mountain, even if visitors arrive at the scheduled time.
