A historic cast iron arch bridge located in Akashi City, Hyogo Prefecture, Japan. Known for its unique double arch structure, along with the nearby Hata Bridge, they are one of the oldest surviving cast iron bridges in Japan. Built in the Meiji era, specifically in the late 19th century, as part of the railway development and industrialization process at that time, it reflects Japan's adoption and integration of Western technology and architectural styles during that period. Not only appreciated for its engineering and architectural value, but also cherished for its position in the history of Japanese bridge architecture. It has become a symbol of Japanese cast iron bridge technology and architectural art.
