Diamond Fuji Viewing Spots, Dates,
and Times in Tokyo

One of the most interesting things about Mt. Fuji I've ever heard of while residing in Japan is what's known as "Diamond Fuji," a phenomenon which occurs only from Oct. to Feb. when the sun sets into or rises out of Mt. Fuji's cone, setting off sunbeams that resemble a glittering diamond. The Diamond Fuji pic below was taken by a Tokyo friend of mine from the shore of Lake Yamanakako, one of Fuji's 5 Lakes.

After a failed attempt to view Diamond Fuji on Dec. 23, 2014 atop Mt. Takao along with hundreds of other photographers and romantics, smiley and a lengthy but very fun Xmas Day Diamond Fuji discussion thread with my friends in the "Hiking in Japan" group @ Facebook, I decided to put together the table below, listing the best high-rise spots in Tokyo for viewing Diamond Fuji along with recommended dates, sunset times, admission fees, and links to Google maps.

  1. Sunset times indicated above are from <>, and reflect the moment the top of the sun disc touches the horizon, therefore, depending on the viewer's altitude, the sun will begin setting into Mt. Fuji's cone much (at least 10-15 min.) earlier.
  2. Diamond Fuji viewing spot names above are linked to their Google maps.
