It is not mount Fuji

It is Mount Yōtei in Hokkaido. Of course, it looks a lot like Fuji. Both of them are stratovolcanoes, so symmetrical that they look like hand-kneaded, both of them covered with a crown of snow when the right time comes.

There are quite a few Fuji look-alikes, partly because of Japanese geology, partly because Fuji is so compelling in the Japanese endocosm, that finding others must have been something of a necessity.

I quote from the guide:

Mount Fuji has been revered for hundreds, if not thousands of years. Its perfect shape and commanding height have made it the undisputed, and sometimes unifying, symbol of the country, even for many Japanese who had never seen it with their own eyes.

Mount Fuji's beauty instilled such awe that villagers and towns throughout Japan began to create their own local version of Mount Fuji to revere, admire, and be proud of.

Today, there are at least 30 mountains known as something-Fuji, often related to the name of the province prior to the new prefectural names adopted in 1868. Hokkaido's Yotei-zan is known as Ezo-Fuji. Kaimon-dake, in Kagoshima Prefecture, is called Satsuma-Fuji. The Iino-yama, in Kagawa Prefecture, is known as Sanuki-Fuji, and so on.
