History

edit

The area around Sekigahara was part of traditional Mino Province. In 1600, the Battle of Sekigahara took place here. During the Edo period it was tenryō territory directly under the Tokugawa shogunate, administered by a hatamoto. During the post-Meiji restoration cadastral reforms, the area was organised into Fuwa District, Gifu Prefecture. The village of Sekigahara was formed on July 1, 1889 with the establishment of the modern municipalities system, and was raised to town status on April 1, 1928. In 1954, Sekigahara annexed the village of Imasu, as well as part of the neighboring town of Tarui. A proposed merger with the neighboring city of Ōgaki was rejected in 2004.
