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. Agate was found in Hanaishi in 1877. Mining was started by Oshima Kanzaemon. Meanwhile, increasing numbers of people arrived in the area to mine existing seams of manganese, gold and silver and by the middle of the Meiji era many had settled in the Shiribetsu river area. The town was granted independent status as the village of Toshibetsu and formed from the neighboring town of Setana in 1897. It was settled by Norioshi Shikata and 15 other families, including the Imamura and Kanamori houses. These families had arrived in the area during the preceding five years and laid out the town into 129 housing sites, a city hall and a police station.
