Origins & Early Life

Ishida Mitsunari (石田 三成; Japanese pronunciation: [i.ɕi.da (|) mʲi.tsɯꜜ.na.ɾʲi], 1559 – November 6, 1600) was a Japanese samurai and military commander of the late Sengoku period of Japan. He is probably best remembered as the commander of the Western army in the Battle of Sekigahara following the Azuchi–Momoyama period of the 16th century. He is also known by his court title, Jibu-no-shō (治部少輔). Mitsunari was born in 1559 in northern Ōmi Province (current Nagahama city, Shiga Prefecture), as the second son of Ishida Masatsugu, a retainer for the Azai clan. His childhood name was Sakichi (佐吉).

Career & Major Achievements

The Ishida withdrew from service after the Azai's defeat in 1573 at the Siege of Odani Castle. According to legend, Mitsunari was a monk in a Buddhist temple before serving Toyotomi Hideyoshi, but the accuracy of this legend is doubtful as it was first recorded during the Edo period. In 1577, Mitsunari met Toyotomi Hideyoshi, when the former was still young and the latter was the daimyō of Nagahama. Later, Mitsunari became one of Hideyoshi’s samurai officers. When Hideyoshi engaged in a campaign in the Chūgoku region, Mitsunari assisted his lord in attacks against castles including Tottori Castle and Takamatsu Castle (in present-day Okayama).

Enduring Legacy & Impact

In 1583, Mitsunari participated in the Battle of Shizugatake. According to the "Hitotsuyanagi Kaki", he was in charge of a mission to spy on Shibata Katsuie's army and also performed a great feat of Ichiban-yari (being the first to thrust a spear at an enemy soldier) as one of the warriors on the front line. Later, he served in the Battle of Komaki and Nagakute in 1584. That same year, he worked as a kenchi (survey magistrate) at Gamo county in Omi Province. In 1585, Mitsunari was appointed as administrator of Sakai, a role he took together with his elder brother Ishida Masazumi.
