The route from Kisennuma, Miyagi Prefecture, to the various sites along the Sanriku coast, to Hachinohe in Aomori Prefecture, is called "hamakaido." In the Edo period Morioka Pass, it was called "Seaside Road". The farmers and fishermen of Sanshuei (Noda-Miyako-Daikan Office), who stood up to endure the mischief of the nephew, raised the flag of Komaru 6 (1853), and sent Sendai I went south along Hamaka Road to the forge. The topography of the beach highway is the Rias coast south of Miyako, and the north is a raised coast. Most of the river flows from the west to the east at a right angle to the coastline, forming a deep valley on the mountain plateau. Therefore, there are many obstacles in the south over the ridge, in the north over the slope and over the valley. Strong roads were used on steep slopes and bad roads as a means of transportation on this severe road, and it was also a road where cows came and gone.
