Yoshitaka Kuki was a naval commander during Japan's Sengoku Period, under Oda Nobunaga, and later, Toyotomi Hideyoshi. He was also the ninth headmaster of the Kuki family's school of martial arts, Kukishin-ryu and thus a very skilled warrior.
Background
Yoshitaka Kuki was the son of Sadataka. He resided at Toba Castle (Mie Prefecture) and was known as Lord of Osumi. The Kuki family was originally from Muro district of Kii province, and had been settled in Shima province by Kuki Takayoshi. The clan became powerful in the Ago district of Shima and developed a reputation as pirates.
Career
Yoshitaka Kuki served the Kitabatake family at Ise Province (Mie Prefecture) and then switched his fealty to Nobunaga Oda (1569).
In the 1570s, Yoshitaka Kuki allied himself with Oda Nobunaga, and commanded his fleet, supporting land-based attacks on the Ikkō-ikki. In 1574, his aid ensured a victory for Nobunaga in his third attempt to attack the Nagashima fortress. In 1576, he was defeated at Kizugawaguchi by the Mōri clan fleet, but 1578 brought victory in the second Battle of Kizugawaguchi, in which Kuki used 'iron ships' to repel the arrows and musket balls of the opposing Mōri clan's ships.
In 1587, Yoshitaka Kuki led Toyotomi Hideyoshi's fleet in a campaign in Kyūshū, alongside Konishi Yukinaga, Wakizaka Yasuharu and Katō Yoshiaki. Three years later, along with Wakizaka Yasuharu and Kato Yoshiaki he went on to lead the Siege of Odawara and the Siege of Shimoda. He continued in his role as commander of Hideyoshi's fleet, launching an invasion of Korea in 1592 from his flagship Nipponmaru. He was severely defeated in the Battle of Myeongryang.
In the Battle of Sekigahara, Kuki Yoshitaka fought alongside the Toyotomi forces, while his son Kuki Moritaka joined the opposing force, under Tokugawa Ieyasu. Following Tokugawa's victory, his son successfully guaranteed Yoshitaka's safety from Ieyasu. In a turn of fate, Yoshitaka committed seppuku before the news reached him.
Later Kuki Yoshitaka enraged at Ieyasu’s decision over the conflict between Yoshitaka and the Inaba family, went into retirement. Returned to side with Mitsunari Ishida during Sekigahara Battle (1600), while his son, Moritaka, sided with Ieyasu Tokugawa. After the battle he fled to Kii, Wakayama Prefecture, for his son’s sake but was forgiven. However, he committed suicide.
