Rumoi

Rumoi grew around the mouth of a river on the Sea of Japan, where an Ainu settlement and the Rurumoppe trading district stood. Salmon, trout and kelp were exchanged here, and fishing vessels gathered at the river mouth. In 1808, according to local history, the district's manager Yamada Bun'emon employed Ainu workers to prepare a mountain route from Rumoi toward the Uryū River basin, connecting the coast with the interior.
