The history of a cedar forest formed from strong cold winds at an altitude of 900m The mountain forests of Sado were managed by the shogunate to secure firewood for use in the refining of gold from the many gold mines that flourished during the Edo Era. However, those trees which became bent from strong winds and heavy snow unique to Sado were left alone. Over many years, the Sado cedar forest formed from nature finally became a distinct part of the island and has come to be protected. In 2011, a walking trail was completed for a part of the natural forest. The trail has become popular for a stroll through the forest, and from the observation point near the exit, a grand view can be enjoyed.
