Tsurugisaki Lighthouse (剱埼灯台, Tsurugisaki tōdai) is a lighthouse located on Cape Tsurugi on the southeastern extremity of the city of Miura, Kanagawa Prefecture, Japan on the southernmost and eastern tip of Miura Peninsula. (On the southernmost western tip of Miura Peninsula stands the Jōgashima Lighthouse.)
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.
