History
Work began in August 1873.[5] The lighthouse was first lit on March 1, 1876, in the Meiji period of Japan. It was one of the lighthouses designed by Richard Henry Brunton, who was hired by the government of Japan to help construct lighthouses to make coastal waters safe for foreign ships to approach, after Japan opened up to the West.
Access
The lighthouse is open to the public. It is accessible by car, bicycle, or public transportation; specifically by bus from Kottoi Station.[6]
