Geologically speaking, located at the end of the Midai river alluvial fan, this region around Tokaichi is suitable for both rice cultivation and dry field farming. In addition to this, the region is close to key agricultural and forestry places: Takata, a paddy region in former Tatomi and Kosai towns; Genkata, a dry field farming region in former Shirane town; and Nekata, a forestry region in Masuho town. All of these geological conditions of Tokaichi made it become a big market place where farm products and agricultural machines were exchanged or sold. They say that the history of the market dates back to the Edo era.
