The Tsurugisaki Lighthouse was one of eight lighthouses to be built in Meiji period Japan under the provisions of the Anglo-Japanese Treaty of Amity and Commerce of 1858, signed by the Bakumatsu period Tokugawa Shogunate. The lighthouse was designed and constructed by British engineer Richard Henry Brunton. Brunton constructed another 25 lighthouses from far northern Hokkaidō to southern Kyūshū during his career in Japan.
Work began in March 1870. The Tsurugisaki Lighthouse was completed on March 1, 1871, and was designed to protect shipping entering Tokyo Bay via the Uraga Channel, with its light visible as far as the Bōsō Peninsula on the eastern shore of the bay. The original structure was destroyed during the Great Kantō earthquake on September 1, 1923, and was replaced with the current reinforced-concrete structure on July 4, 1925. The lighthouse has been unmanned since 1991.
It is currently maintained by the Japan Coast Guard.
