Geography
Imakane is located in southern Hokkaido within Setana District, Hiyama Subprefecture. The town is on Route 230 at the junction of the Shiribeshi-Toshibetsu and Toshibetsu-Mena rivers. The main landmark and meeting point in the town center is De Molen, a large windmill.
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.
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.
Toshibetsu village formally received the name of Imakane in 1947 as part of its upgrade to town status. The name was taken from the family names of its two celebrated pioneers, Imamura (今村) and Kanamori (金森).
The town's constitution was established on October 1, 1967. Imakane celebrated its 100th year of autonomous government on July 15, 1997.

The symbol of Imakane comprises the meandering Toshibetsu River and the 1st letter of 農耕 (farming) which can be written in katakana as ノ and pronounced "no". This symbol was decided upon by a public competition on the town’s 70th anniversary (1967)
Another symbol of Imakane is a large windmill located in the center of town where the old train station stood. It is called "De Moren Imakane". The Name "De Moren" is Dutch for "windmill". In Spring the tulips come into bloom and is one of the symbols for Imakane.
