"Sumiko Hiroba", located near the center of the park, can be used not only as a place for children’s playgrounds and recreation, but also as a relaxing place to exercise, yoga, and spend slowly. If you want to use "Sumiko Hiroba" at events, etc., you can also make a reservation in the Park Concierge Building / HP. In addition, the "Matsunomori Village" adjacent to Sanko Hiroba has a lively facility that is divided into the three buildings of A, B and C, so you can enjoy eating while looking at the sea. Please find a place.
