The Hagi Reflection Furnace, located in Chubu, Hagi City, Yamaguchi Prefecture, is the remains of a reflection furnace used for metal smelting and cannon casting during the 19th century. This site is a significant industrial heritage that symbolizes the technological innovation during Japan's modernization process and was registered as a UNESCO World Heritage site in 2015 under the title 'Sites of Japan's Industrial Revolution: Iron and Steel, Shipbuilding and Coal Mining.' Today, the surviving chimney ruins serve as a precious historical monument that conveys the advanced technical capabilities of that era.
A reflection furnace is a structure designed to reflect heat to increase efficiency. The Hagi Reflection Furnace stands as a witness to the era when Japan sought to establish domestic manufacturing technology by introducing Western techniques during its modernization. There are only two such near-modern reflection furnaces remaining in Japan—the Hagi Reflection Furnace and the Nirayama Reflection Furnace in Shizuoka Prefecture—making this site extremely rare. In 1924, it was designated as a National Historic Site. This site is not merely an old structure; it holds profound cultural value, telling the story of a time when Japan's industrial structure underwent dramatic changes.
