Nikkō Tōshō-gū
Imakane, at the time known as Hanaishi, was founded in the Kan'ei period between 1624 and 1643 after gold, silver and manganese were discovered in the upper Shiribetsu River, near Pirika/Hanaishi. Some of the gold mined from the area was used to build Nikkō Tōshō-gū, a Shinto shrine in Tochigi Prefecture dedicated to Tokugawa Ieyasu.
