The Battle of Sekigahara was an important battle in Japan which occurred on October 21, 1600 (Keichō 5, 15th day of the 9th month) in what is now Gifu Prefecture, Japan, at the end of the Sengoku period.
This battle was fought by the forces of Tokugawa Ieyasu (Real Life) against a coalition loyal to the Toyotomi clan, led by Ishida Mitsunari (Real Life) on behalf of the young child Toyotomi Hideyori, from which several commanders defected before or during the battle, leading to a Tokugawa victory. The Battle of Sekigahara was the largest battle of Japanese feudal history and is often regarded as the most important.
Mitsunari's defeat in the Battle of Sekigahara is generally considered to be the beginning point of the Tokugawa shogunate, which ruled Japan for another two and a half centuries until 1868.
