These trees were planted by the magistrate Okubo Nagayasu under order of the Shogunate in 1604 to protect people traveling along the Tokaido Path from the heat of summer and strong winds in winter. There are around 300 large pine trees lined up for 600m from Goyu to Akasaka post towns still intact from the olden days. These popular trees are designated as a national natural monument among the many trees on the Tokaido Path.
