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 when the sun sets into or rises out of Mt. Fuji's cone, setting off sunbeams that resemble a glittering diamond. Because Mt. Fuji lies southwest of Tokyo, Diamond Fuji is visible at sunset from most locations in the nation's capital only from Oct. to Feb. The Diamond Fuji pic below was taken by a Tokyo friend of mine from the shore of Lake Yamanakako, one of the Fuji 5 Lakes.

And WOW, check out this 34-sec. timelapse video of the Diamond Fuji taken Feb. 19, 2021 by a Weathernews staffer from the shore of Lake Yamanaka.
(If the player above is not visible, you can view video at YouTube here.)

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 at 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 may begin setting into Mt. Fuji's cone (perhaps as much as 10-15 min.) earlier. [ has since bit the dust, so I recommend using this site for sun tracking:]
  2. Diamond Fuji viewing spot names above are linked to their Google maps.
