Ishikawa Kazumitsu served as a bushō during the Azuchi-Momoyama period.
Kazumitsu was born as the third son of Ishikawa Iemitsu.
His oldest brother, Ishikawa Mitsumasa, served as the lord of Kagashima Castle in the Atsumi District of Mino Province. His second oldest brother, Ishikawa Mitsushige, served as a magistrate responsible for mountainous areas in Tanba Province.
His parents and siblings all served Hashiba Hideyoshi as hereditary retainers. Kazumitsu was an umamawari, or member of the mounted cavalry.
In the fourth month of 1583, at the Battle of Shizugatake, Kazumitsu served on the front line of the spear-wielding soldiers, contributing on a par with those intrepid bushō known as the Seven Spears of Shizugatake. During this battle, however, he was stabbed in the eye by Haigō Ieyoshi (Gozaemon) and died. As recognition for Kazumitsu’s valor in battle, his youngest brother, Ishikawa Yoriaki, was awarded a written commendation and fief of 1,000 koku on behalf of Kazumitsu.
According to one account, on the evening before the battle, Kazumitsu got into an argument with Fukushima Masanori which almost led to a clash of swords. Owing to the major battle planned the following day, he was restrained by those around him and declared that others would see him from behind on the battlefield. The next day at Yanase, he charged the enemy on his own from the front lines of the spear-wielding soldiers and died in battle.
In another account, at the Battle of Shizugatake, Kazumitsu and Akita Suke-emon were responsible for the battle flags. Kazumitsu had a homosexual interest in Katō Yoshiakira so he took off his helmet to give to Yoshiakira. Yoshiakira angrily discarded the helmet declaring that he could not wear someone else’s helmet in battle. Kazumitsu then charged the enemy from the front lines without a helmet after which he was stabbed by an enemy spear above the left eye and died.
