The park is located on an artificial hill. Soil was brought in to create an elevated spot from which shipping agents could look out to sea and watch for merchant ships. Hiyori means good weather, and yama means hill. The artificial hill also protects the city from strong winds. The park has a great view of the port and many historical items that include the oldest stone compass and oldest wooden lighthouse in Japan, and a half-sized replica of the kitamae cargo ships that came to port. The ship can be boarded by crossing a bridge. The graceful sun setting over the Japan Sea can be seen from the lookout point.
