Diamond Fuji is a phenomenon that occurs when the sun seems to sit directly above the summit of Mount Fuji, looking like a sparkling diamond atop the mountain. It happens most often during the winter solstice when the days are shorter.

This visual wonder can materialise at either sunrise or sunset depending on the place and time. Each year predictions are made for each viewing spot so you know when to go and when to pray for the clear skies that will allow the best view.

If you live in Tokyo, witnessing this marvel of nature is as easy as a trip to Roppongi Hills Mori Tower. On 8th February 2018 you should be able to see it after 5pm from the Tokyo City View Sky Deck. The panoramic view of Tokyo means you can appreciate natural and man-made wonders all in one glance.

Diamond Fuji can also be seen from Tokyo Skytree, Tokyo Metropolitan Building and all the other inner city viewing towers but of course, it will occur on different dates depending on location, so it's important to research beforehand.

If you're willing to go further afield you can find even more spectacular views.

Diamond Fuji can be viewed from the top of Mount Minobu in Yamanashi, accessible by hiking or via the Minobusan Ropeway. The area can be reached by train, taking only one hour and a half from Shinjuku station. There are several other viewing spots dotted around Yamanashi prefecture.

Lake Tanuki on the Shizuoka prefecture side of the mountain is where you can view 'Double Diamond Fuji'. The lake's waters are so clear that the scene is reflected underneath to dazzling effect. However, it seems difficult to access from Tokyo taking 4 hours by public transport or a 3 hour drive. This really is a pilgrimage for those desperate to see the fabled double diamond. Making that kind of trek for only a few minutes, no matter how wonderful, may be a hard pill to swallow. But if you manage to make the trek you can also enjoy hiking and camping in the area.
