Kuki Yoshitaka entered the world in Shima, along the southern coast of Mie Prefecture, in 1542. Hailing from a family that once held mastery over two castles, Yoshitaka faced adversity early on. At the tender age of nine, his father's demise plunged the family into hardship, resulting in the loss of their territories and a life on the run.
When Oda Nobunaga launched an invasion into the neighboring Ise province, targeting Kitabatake Tomonori and the Kitabatake clan in 1569, Kuki pledged loyalty to Nobunaga. He played a pivotal role by providing naval support for the annexation of Mie. Kuki showcased his maritime prowess during the naval blockade of the Nagashima Ikko-Ikki uprising, aiding Nobunaga in overcoming the militant followers of the Hongan-ji Temple.
In the Battle of Kizugawaguchi in 1576, where Kuki faced superior naval forces from the Mori clan, his ships were set ablaze at sea. Enraged by the defeat, Nobunaga tasked Kuki Yoshitaka with devising a strategy to conquer the Mori fleet. In response, Yoshitaka created what is believed to be the world's first ironclad warships in 1578. Deploying six of these formidable vessels, accompanied by a fleet of smaller ships, Kuki confronted a Mori armada comprising 600 vessels.
The ensuing Second Battle of Kizugawaguchi resulted in victory for Yoshitaka, earning him additional territories and a promotion to daimyo status.
In 1582, Kuki Yoshitaka served Nobunaga's son, Nobukatsu, during the tumultuous Honno-ji Incident orchestrated by Akechi Mitsuhide. Two years later, he aligned with former Oda clan statesman Takigawa Kazumasu in the service of Toyotomi Hideyoshi, participating in the Battle of Komaki Nagakute against the Tokugawa. Remaining a loyal vassal of the Toyotomi clan, he received the Toshi-gun in the Toba region, where he constructed Toba Castle in 1585.
As the Battle of Sekigahara unfolded in 1600, Yoshitaka sided with the Toyotomi loyalists of the Western forces led by Ishida Mitsunari. However, strategically, his son Moritaka fought for the Eastern side with the Tokugawa clan. This tactical move aimed to secure the family name's preservation, ensuring a family member's presence among the victors. Following the defeat of the Western forces, Yoshitaka abandoned Toba Castle and retreated to Toshijima, the largest island off Toba's coast.
Simultaneously, his son Moritaka sought clemency for his father from Tokugawa Ieyasu, securing an amnesty. Unfortunately, news of the pardon reached Yoshitaka on Toshijima after he had already performed seppuku.
He passed away at the age of 58, in close proximity to the foundation of his cherished naval fleet. Per his wishes, his head rests atop a hill overlooking Toba Castle, while his body finds its final resting place at the hill's base.

Miyoshi Chokei

The eldest son of Miyoshi Nagamoto (Motonaga), at the age of seventeen and with the support of Miyoshi Masanaga and Matsunaga Hisahide, invaded Kinai, the inner provinces of Japan, and in 1539 seized control of Kyoto. In 1543 he expelled Hosokawa Ujitsuna from the commercial city of Sakai and appointed his own brother, Sōgo Kazunari, as the city’s new leader. In 1548 he took the name Chōkei. When a conflict arose between him and Masanaga, Chōkei appealed to his liege lord, Hosokawa Harumoto, asking him to raise troops in the provinces of Settsu, Izumi, and Kawachi, but Harumoto instead chose to ally with Masanaga against Chōkei.

Matsudaira Ietada, also known as Tomomo-no Suke, was the eldest son of Matsudaira Koretada, the head of the Fukozu branch of the Matsudaira clan. Ietada was born in 1555 at Fukozu Castle. When he reached adulthood (for samurai children this age range was between 11 and 17), the Fukozu-Matsudaira clan was under the authority of Tokugawa Ieyasu and commanded by Sakai Tadatsugu. In the Battle of Nagashino in 1575, Tadatsugu’s unit, which included both Ietada and his father, took part in the assault on the fort on Mount Tobigasu-yama. During the fighting, Koretada was killed, and twenty-year-old Ietada became the new head of the clan.

In the Battle of Komaki–Nagakute in 1584, Nagamori took at least two enemy heads.

Magara Jurōzaemon Naotaka

Magara Jurōzaemon Naotaka was a vassal of Asakura Yoshikage from the province of Echizen, and very little is known about his life, including even the exact year of his birth. Magara gained his renown through his heroic death at the Battle of Anegawa in 1570. In this battle, the combined forces of Oda Nobunaga and Tokugawa Ieyasu confronted the armies of Asai and Asakura, with Ieyasu taking command of the left flank and fighting against the Asakura forces. After crossing the shallow Anegawa River, which separated the two armies, Tokugawa’s finest generals — Honda Tadakatsu and Sakakibara Yasumasa — launched an assault on the headquarters of Asakura Kagetake, the commander-in-chief of the Echizen army. The attack by Honda Tadakatsu was so swift that Kagetake found himself almost completely surrounded by enemy troops.

Kusunoki Masashige

Kusunoki Masashige was, without exaggeration, a genius of guerrilla warfare. If not for this talented commander, Emperor Go-Daigo would likely have failed not only to ascend the throne, but even to put up any real resistance against the powerful Hojo clan.

After the death of his father, Mōri Motonari, Takakage effectively governed the Mōri clan for many years while serving as advisor to his nephew, Mōri Terumoto.
