Ogasawara Tadamasa, the first feudal lord of the Akashi domain, built Akashi Castle and improved the port at the same time. It is said that he dredged a port and built stone retaining wall to construct the port. The canal called Horikawa was made from the east of the port to the place of Nakasaki Auditorium. In those days Nakasaki was made of sand from the port and they built sailors’ housing and anchorage afterward.
