Jinsekikōgen is located in eastern Hiroshima. The town area is generally located on a plateau with an elevation of 400 to 700 meters, and consists of basalt and red soil layers. Part of the area forms a limestone karst plateau, and the rivers that flow through this area carve out valleys. The surrounding highlands came to be known as the Jinseki Plateau.

The area of Jinsekikōgen is part of ancient Bingo Province, but has close cultural and economic ties neighboring Bitchū Province. During the early Edo period, it was part of the holdings of the Mizuno clan of Fukuyama Domain under the Tokugawa shogunate; however, after the attainder of that domain, most of the area became an exclave of Nakatsu Domain of Buzen Province. Following the Meiji restoration, the area was organized into villages with the creation of the modern municipalities system on April 1, 1889. Jinsekikōgen was created on November 5, 2004 from the merger of the towns of Jinseki, Yuki and Sanwa, and the village of Toyomatsu. Before Toyomatsu was incorporated, it was the last remaining village within Hiroshima Prefecture.^{[citation needed]}
