History

Although not one of the eight lighthouses stipulated specifically by the provisions of the Anglo-Japanese Treaty of Amity and Commerce of 1858, the Irōzaki Lighthouse was one of the earliest of the 26 lighthouses to be built in Meiji period Japan by British engineer Richard Henry Brunton, and was the tenth western style lighthouse to be completed in Japan. Its construction was given priority by the Meiji government due to the frequency of marine accidents off the Izu Peninsula. The original structure as designed by Brunton was octagonal, and was constructed of wood.

The Irōzaki lighthouse was completed on October 5, 1871. This structure was destroyed during a wind storm on November 14, 1932 and was replaced with the current reinforced concrete structure on March 31, 1933. Its lens was upgraded and structure repaired in 1993.

The Irōzaki Lighthouse is listed as one of the “50 Lighthouses of Japan” by the Japan Lighthouse Association. It is operated by the Japan Coast Guard.
