The Osarizawa Mine has a long history, and is a large-scale copper mine, representative of Japan.
This mine began to be on the decline about the year of 1966, and it was closed on May 31, 1978. This closure is due to the exhaustion of high-quality mine, the lowering of the price of copper caused by the increase of the imported mineral and the high evaluation of ‘yen’.
The decline of this mine has had a great deal of influence over the related, subcontracted plants, the local commerce, economy, and administration. And the local culture and education was influenced as well.
This decline also brought about the critical influence over the Osarizawa district, and especially the southern part of the Kazuno Basin was terribly affected.
The closing of this mine was carried out, showing an unprecedented smooth procedure.
