Wooden Lighthouse Scenic Postmark dated 9th May 1986 Sakai

     This wooded, hexagonal Western-style lighthouse stands 11.3 meters tall and is located on old Sakai Harbor's southern seawall. The structure was funded with donations from the citizens of Sakai. Completed in 1877, the lighthouse helped protect ships as they came and went from Sakai Harbor for nearly 100 years. The progressive reclamation of land from the sea forced its closure in 1968. It remains today as one of the symbols of Sakai and has been designated a national historic site in recognition of its status as one of Japan's oldest wooden Western-style lighthouses. (The interior is not open to the general public.)
