Mount Hōō (鳳凰山, Hōō-zan) is located in the western portion of Yamanashi Prefecture, Japan.

Because the mountain has three peaks, it is also called Hōō Sanzan (鳳凰三山).

It is in Minami Alps National Park[1] and is one of the 100 Famous Japanese Mountains.

Mount Hōō has three peaks: Mount Hōō is separated from most of the other mountains in the Akaishi range, giving a wider view of the surrounding mountains.

Also, most mountains in the range have a reddish-brown color ("Akaishi" means "red stone" in Japanese), but Mount Hōō and Mount Kaikoma are the two exceptions, as they are granite mountains.
