At the age of 15, Hosokawa Tadaoki engaged in his first battle under the command of Oda Nobunaga. In 1580, he was granted the Tango domain in present-day northern Kyoto Prefecture and entered into an arranged marriage with the daughter of Akechi Mitsuhide, another trusted general of Oda Nobunaga.
This strategic union aimed to fortify the bonds among Oda's vassals. However, when Mitsuhide betrayed and killed Nobunaga in the Honnoji Incident, seeking aid from Tadaoki and his father Fujitaka, both refused to assist. Tadaoki later fought alongside Toyotomi Hideyoshi in the Battle of Komaki Nagakute in 1584 and participated in the Siege of Odawara against the Hojo Clan in 1590.
Renowned for his literary and poetic prowess, Tadaoki, like his father Yusai, was a skilled practitioner of the tea ceremony, having studied under the esteemed tea master Sen no Rikyu. Despite his proficiency in cultured pursuits, Tadaoki was known for his formidable temper.
In 1600, leading up to the Battle of Sekigahara, Tadaoki and his father aligned with the Tokugawa, driven in part by the Western forces' attempt to take Tadaoki's wife, Gracia, hostage, resulting in her tragic death during an attack on their mansion by Ishida Mitsunari's forces. Tadaoki's father defended Tanabe Castle against a substantial Western force, preventing them from joining the main conflict at Sekigahara.
Commanding a force of 5,000 samurai at Sekigahara, Tadaoki engaged in intense hand-to-hand combat, directly clashing with Shima Sakon's troops near the Toyotomi Loyalists' base on Mt Sasao. Post-Sekigahara, Tadaoki received land in Kokura and participated in the Sieges of Osaka in 1614 and 1615 before retiring in 1620. He passed away at the age of 82 and was laid to rest at Kyoto's Daitoku-ji Temple, beside his wife, Gracia. Following her death, he remained single for 46 years.

Matsudaira Kiyoyasu (September 28, 1511 – November 29, 1535) served as the 7th lord of the Matsudaira clan during Japan's tumultuous Sengoku period. Renowned as the paternal grandfather of Tokugawa Ieyasu, one of Japan's "great unifiers," Kiyoyasu expanded his clan’s influence, bringing all of northern Mikawa Province under his control after subduing the Saigo clan. His power was further symbolized by the construction of Okazaki Castle, a testament to the Matsudaira’s growing dominance. Matsudaira Hirotada (June 9, 1526 – April 3, 1549) was a daimyo and lord of Okazaki Castle in Mikawa Province during Japan’s turbulent Sengoku Period. He is best known as the father of Tokugawa Ieyasu, the founder of the Tokugawa shogunate. Ikeda Tsuneoki (1536 – May 18, 1584), also known as Ikeda Nobuteru, was a prominent daimyo of the Ikeda clan and a distinguished military commander during Japan's Sengoku and Azuchi-Momoyama periods. He served under the influential warlords Oda Nobunaga and Toyotomi Hideyoshi.

Oda Nobutaka (1558–1583) was a samurai of the Oda clan, also known as Kanbe Nobutaka after being adopted as the head of the Kanbe clan, which governed the central region of Ise Province. He was the third son of Oda Nobunaga, born to a concubine named Sakashi. Nobutaka was referred to as "San Shichi," possibly because he was born on the seventh day of the third month in the Japanese lunar calendar. However, there is a theory suggesting he was born twenty days earlier than his elder brother, Oda Nobukatsu, but due to delays in reporting and the low status of his mother’s family, he was acknowledged as Nobunaga’s third son. Yamauchi Kazutoyo (also spelled Yamanouchi; 1545/1546? – November 1, 1605) was a prominent samurai and retainer who served Oda Nobunaga and later Toyotomi Hideyoshi during Japan's Sengoku and Azuchi-Momoyama periods. His father, Yamauchi Moritoyo, was a descendant of Fujiwara no Hidesato and a senior retainer of the Iwakura Oda clan, which opposed Oda Nobunaga. Moritoyo was also the lord of Kuroda Castle in Owari Province. Kazutoyo is especially renowned for his marriage to Yamauchi Chiyo, whose wisdom and resourcefulness played a key role in his rise to prominence. Saito Tatsuoki (6 September 1548 - 1573) was a daimyo of Mino Province during Japan's Sengoku period and the third-generation lord of the Saito clan. He was the son of Saito Yoshitatsu and grandson of Saito Dosan. His mother was a daughter of Azai Hisamasa, making him a nephew of Azai Nagamasa and a relative of Oda Nobunaga's first wife, Nohime, who was also a daughter of Saito Dosan. Kyogoku Tadataka (1593–1637) was a Japanese nobleman and the head of the Kyogoku clan during the early 17th century, a pivotal time marked by the Tokugawa consolidation of power.
