About

Mount Iō (硫黄山, Iō-zan) also Mount Iwo is a volcano in the Akan Volcanic Complex of Hokkaidō, Japan. It sits within the borders of the town of Teshikaga.

The mountain was once mined for sulphur, hence its name. To the Ainu the mountain was known as Atosanupuri (naked mountain). The mountain is quite bare. Despite its bareness and being a rather low mountain at 508 metres (1,667 ft) it hosts alpine plant life. It hosts colonies of Siberian Dwarf Pine, Rhododendron diversipilosum, and other members of Ericaceae.
