Master of the Sengoku Seas Who Commanded the Iron-Clad Warships
Description
The Sengoku Master Who Dominated the Seas
Born in Tenmon 11 (1542) in Shima Province (present-day Shima City, Mie Prefecture), Kuki Yoshitaka served Oda Nobunaga and Toyotomi Hideyoshi as commander of the Shima Kuki naval force and the Sengoku period's mightiest naval commander. Yoshitaka, to whom Nobunaga gave the epithet "Pirate Admiral," dominated the Seto Inland Sea, Kumano-nada, and Ise Bay, and left his mark on Japanese history as an innovator of naval military strategy.
The Construction of Ironclad Ships and the Second Battle of Kizu River Mouth
Yoshitaka's greatest achievement to be remembered in history was the use of ironclad ships in the Second Battle of Kizu River Mouth in Tensho 6 (1578). After being defeated by the Mōri naval force in the First Battle of Kizu River Mouth, the Oda forces, at Yoshitaka's proposal and on Nobunaga's command, constructed the revolutionary "ironclad ships" with hulls covered in iron plates. These ironclad ships neutralized the Mōri naval force's fire attacks and succeeded in cutting off the supply routes to Ōsaka Ishiyama Hongan-ji, bringing about a revolutionary transformation in naval warfare during the Sengoku period.
Service to Hideyoshi and the Korean Campaign
After Nobunaga's death, Yoshitaka served Toyotomi Hideyoshi and was active in naval operations in various locations. During the Bunroku-Keicho Campaign (1592–98), he led the Kuki naval force and participated in operations along the Korean coast, playing an important role as a naval commander. However, in battles against the turtle ships led by Yi Sun-sin of the Korean navy, he faced severe challenges, and also experienced the difficult aspects of naval warfare.
The Tragedy of Sekigahara—Father and Son Divided
In the Battle of Sekigahara in Keicho 5 (1600), Yoshitaka sided with the Western Army (Ishida Mitsunari faction) while his son Moritaka sided with the Eastern Army (Tokugawa Ieyasu faction). After the Eastern Army's victory, Yoshitaka fled to Tōshi Island, but took his own life before news arrived that his pardon had been decided through Moritaka's petition. The tragedy of Sekigahara, where father and son opposed each other, became a sorrowful tale of the Kuki family passed down to later generations.
The Naval Commander and Swords
Regarding the swords favored by Kuki Yoshitaka, they were primarily practical uchigatana and wakizashi suited for actual combat at sea. He is said to have favored blades forged by master smiths from Ise and Owari, along with swords made by local Shima swordsmiths. The relatively short uchigatana and wakizashi, designed for close-range combat on the deck as a naval commander, reflected Yoshitaka's practical warrior style.
Notable Swords
- Shima uchigatana (Kuki naval sword) — a practical, medium-length blade suited for close quarters aboard warships; the sword of the man who built Japan's first iron-clad fleet carries the pragmatic martial spirit of the Sengoku sea commanders
- Ise wakizashi — a short companion blade by smiths of the Ise-Shima region, designed for the rapid draw and confined fighting space of a ship deck; the weapon of a warrior who understood that the sea demands different tools than the land
