It is in Minami Alps National Park and is one of the 100 Famous Japanese Mountains. Outline 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. History Metal ore was found in the mountain during the Sengoku period and, by the Edo period, the mountain was exploited for its metals and forest products. In 1904, Walter Weston became the first to climb the obelisk on top of Jizōdake. On June 1, 1964, this area was specified to the Minami Alps National Park. In 1990, Sumie Tanaka (田中澄江 Tanaka Sumie) completed New Flowers of the 100 Mountains, which featured many of the alpine plants on Mount Hōō.
