Historic Site Osarizawa Mine (Kazuno City, Akita Prefecture)

One of the largest old mine sites in Japan with 1,300 years of history

Historic Site Osarizawa Mine, which is recognized as a Heritage of Industrial Modernization site, is believed to have opened 1,300 years ago. Inside the tunnels, the Earth's crust from about 9 million years ago is exposed, and you can experience up close the remains of one of the largest copper vein mining complexes in Japan. It is also said that gold from the Osarizawa Mine was used in the construction of Chusonji Temple's Konjikido (golden hall) in Hiraizumi and the Great Buddha in Nara. A variety of routes to tour the tunnels and experiences are available, so the mine is recommended for experience-based learning.
