The Nirayama Reverberatory Furnace (BR˘F, Nirayama Hansharo) is a well preserved iron smelting facility on the Izu Peninsula. Built by the Tokugawa government in 1857, the furnace represents the start of modern iron production in Japan. The Nirayama Furnace is the most complete reverberatory furnaces still standing, and the site received world heritage status in summer 2015 among the Sites of Japan's Meiji Industrial Revolution.

Originally part of a larger factory complex, the furnace was constructed of local stones and bricks. It represented the most advanced technology of the time, and iron produced there was processed on site and cast into cannons, which were desperately needed to shore up the country's coastal defenses in response to the arrival of Commodore Perry and his black ships. Visitors can approach the furnace bodies and four, 15.7 meter high chimneys, which stand encased in protective steel frames. A few cannons are also on display around the furnace, while a small information center and a few shops and restaurants are located nearby.
