Diamond Fuji, a mystical phenomenon where the setting sun overlaps perfectly with the peak of Mt. Fuji.
In Japan, Mt. Fuji is regarded as such a sacred mountain that Sengen Shrine was built on the summit. The sun as represented by the Japanese deity Amaterasu O-Mikami is also worshipped throughout Japan.
“Diamond Fuji”: a collaboration between Mt. Fuji and the sun, two Japanese objects of worship.
In Chiba City, which is home to the longest man-made seashore in Japan, it is possible to see spectacular views of Diamond Fuji across Tokyo Bay by changing locations slightly every day. The opportunity to admire the view from Chiba City is available every year in October and February for roughly ten days at a time.
If the weather conditions are just right, you can see from Makuhari Beach near Makuhari Messe.
Why not make a memory on the Chiba City shoreline and bask in the view of Diamond Fuji?
