, or Nyūdō Saki Lighthouse, is a lighthouse on the northwest top of Oga Peninsula in the city of Oga, Akita Prefecture, Japan.[4]
The first lighthouse was built in 1898,[5] a white hexagon 24.4 meter steel tower. It was electrified with a 1,500W lamp in 1932 and manned until 1972, when it transitioned to automatic control. From 1973 Nyudozaki carries a continuous white spotlight that shines on the Mizushima Islet about 1,000 meters to the north. It is currently one of the 16 Japanese lighthouses which is open to the public,[1] who may climb to the top for a panoramic view over the Sea of Japan (not available in winter season). A small museum has been attached since 1998 displaying references and lenses.[1] The tower is listed as one of the “50 Lighthouses of Japan” by the Japan Lighthouse Association and operated by the 2nd Regional Coast Guard Headquarters.
