Hori Teien is the estate of the Hori family in the small settlement of Muraki about 10km west of Tsuwano in Shimane, and is well worth a visit if you are interested in Edo Period manor houses and traditional gardens.
About 300 years ago the Tokugawa Shogunate claimed the area as theirs as there was a small copper mine here and they installed their loyal vassals the Hori family to oversee it. The Hori were known as The Mining Kings as they also oversaw the nearby silver mine Iwami Ginzan.
The manor house burnt down in 1788, so the current manor house dates from this time. The whole house is open to visitors, including the huge kitchen, bathroom, etc and in an ancillary building is a small collection of historical artifacts including the obligatory suit of samurai armor.
