The wharf was for loading locally quarried stones for shipment to Osaka Castle. There was a quarry nearby that was owned by Nakagawa Hisamori, daimyo of the Bungo Takeda domain. It is known that even after the completion of Osaka Castle, Matsudaira Naomasa, daimyo of the Izume Matsue domain, kept the quarry in operation under a license from the shogunate.
