Mt.Usu, in south west Hokkaido has been active since the Edo period in 1663. Recently, Mt.Usu has been erupting every 20\uff5e50 years, so to coexist with the volcano has become an important theme to the surrounding area.<\/p>\n\n\n\n

It is highly important for residents to correctly understand the characteristics of the volcano and pass on both the wisdom to mitigate a disaster and the memories of the eruptions in preparation for the next eruption.<\/p>\n\n\n\n

People who have learned the nature and characteristics of Lake Toya and the Usu Volcano area and pass on both the memories and experiences of eruptions and the wisdom to mitigate a disaster to the next generation in and outside the community are certified as Volcano Meisters<\/strong>.<\/p>\n\n\n\n

Certified Volcano Meisters are required to improve the community\u2019s ability to mitigate a disaster and work to promote the appeal of the community. Volcano Meisters are learners and communicators of knowledge and experience.<\/p>\n\n\n\n
