Kuroda Toshitaka served as a bushō during the Sengoku and Azuchi-Momoyama periods. As a retainer of the Kuroda clan, he was included among a group of retainers called the Twenty-Four Elite of the Kuroda and, within this group, the Eight Tigers of the Kuroda. He had the common names of Jirō, Shoichirō, and Hyōgo-no-suke.
In 1554, Toshitaka was born as the second son of Kuroda Mototaka in Himeji in Harima Province. Kuroda Yoshitaka (Josui) was his older brother of a different mother.
In 1577, after the commencement of the Invasion of Chūgoku by Oda Nobunaga, Toshitaka joined his older brother, Yoshitaka, to participate under the command of Hashiba Hideyoshi, becoming umamawari, or mounted soldiers, in the Hashiba army. Toshitaka joined in the Battle of Miki from 1578 to 1580, and, thereafter, the assault on Aga Castle, becoming the chamberlain of Machitsubo Castle. After the death of Nobunaga in a coup d’état known as the Honnō Temple Incident in the sixth month of 1582, Toshitaka served on behalf of Hideyoshi at the Battle of Bitchū-Takamatsu and the Battle of Yamazaki. In 1584, at the Battle of Komaki-Nagakute, Toshitaka joined his nephew, Kuroda Nagamasa, to subdue an uprising in Izumi Province.
From 1586 to 1587, Toshitaka participated in the Conquest of Kyūshū. Around this time, upon the urging of Yoshitaka, Toshitaka was baptized as a Christian in Yamaguchi in Suō Province. After the conquest, as an outcome of the allocation of territory, Toshitaka’s brother, Yoshitaka, received six districts in Buzen Province and became the lord of Nakatsu Castle in Buzen whereupon Toshitaka received 10,000 koku from Yoshitaka and became the lord of Takamori Castle in Buzen.
After retirement, Toshitaka’s brother, Yoshitaka, was succeeded by his nephew, Nagamasa, while Toshitaka served as the guardian for Nagamasa. Beginning in 1592, Toshitaka served as the leader of a unit for the Bunroku Campaign on the Korean Peninsula. In 1596, after the commencement of peace negotiations, Toshitaka returned to Japan. Thereafter, he experienced deteriorating health and died during convalescence in Sakai in Izumi Province at the age of forty-three.
