Hashino iron mining and smelting site, Industrial heritage site in Kamaishi, Japan.
The Hashino iron mining and smelting site in Kamaishi preserves the stone foundations of three western-style blast furnaces, the oldest in Japan, built in 1858–1860. The complex includes the furnace bases, a water channel, and the remains of the mining area 2.6 km south, where open-pit shafts and a transport route survive.
Engineer Ōshima Takatō founded this industrial complex in 1858, introducing Western-style blast furnace technology based on Dutch engineering knowledge. This facility became a turning point for Japanese iron production during the late Edo period.
The site's Japanese name, Hashino kōro ato, means "Hashino blast furnace ruins". From 1868 the domain ran a mint here, striking coins with iron from the furnaces; minting continued illegally after the government ban of 1869 until it was discovered in 1871. The American Society of Metals named the site a historical landmark in 1984.
The site sits in a rural area near Kamaishi and is best visited by walking or using local transport to reach it. Wear proper footwear since the grounds are uneven and many structures are displayed outdoors without full shelter.
In 1984 the American Society of Metals named the site a historical landmark, citing its role in the development of the Yawata Iron and Steel Works. The No. 3 furnace was rebuilt from the earlier trial furnace after the first two were built in 1860.
