Mount Io, Active volcano in Kokonoe, Japan.
Mount Io rises to 1580 meters in elevation, featuring two explosion craters and a lava dome within the Akan Volcanic Complex.
The geological formation of Mount Io began over 240,000 years ago, with documented eruptions starting from 850 AD and continuing through 1936.
The indigenous Ainu people named this location Atosa-nupuri, referring to its bare slopes caused by constant volcanic activity.
Visitors can reach Mount Io through multiple bus services from surrounding cities, with a visitor center offering information about the volcanic system.
The mountain slopes contain fumaroles releasing sulfurous steam, creating distinct conditions where specialized alpine plants grow.
