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.
In 1568, after Nobunaga secured control of Ise Province, Nobutaka became the head of the Kanbe clan, ruling from Kanbe Castle near present-day Suzuka, Mie. In contrast, his brother Nobukatsu was adopted into the powerful Kitabatake clan and governed a much larger territory in southern Ise. Missionaries of the time noted that Nobutaka had a better character than Nobukatsu, despite holding a smaller domain.
In 1577, Nobutaka led a successful siege of Ota Castle (near modern Wakayama Castle) and suppressed the Jōdo Shinshū Buddhist uprising (Saika Ikki) in Kii Province. By 1582, Nobutaka was tasked with leading an army against Shikoku, commanding notable retainers such as Niwa Nagahide and Tsuda Nobuzumi, the son of Nobunaga’s younger brother, Nobuyuki.
Before the campaign began, Nobunaga was assassinated by Akechi Mitsuhide at Honnō-ji. Upon learning of his father’s death, Nobutaka returned to Osaka and executed Nobuzumi, who was married to Mitsuhide’s daughter, suspecting him of collusion with Mitsuhide. Though there was no evidence to support this, Nobutaka’s actions underscored the chaos of the period. He then allied with Hashiba Hideyoshi (later Toyotomi Hideyoshi), and together they defeated Mitsuhide’s forces at the Battle of Yamazaki.
After Nobunaga's death, disputes over succession arose. Nobutaka and Nobukatsu clashed during a council at Kiyosu Castle. Ultimately, Oda Hidenobu was declared Nobunaga’s heir. Nobutaka was granted Mino Province, previously ruled by his eldest brother, Oda Nobutada, who had been killed by Mitsuhide. However, this reward fell short of Nobutaka's expectations.
In 1583, Nobutaka allied with Shibata Katsuie and Takigawa Kazumasu in a rebellion against Hideyoshi. The alliance faltered when Nobutaka was besieged at Gifu Castle by Nobukatsu, Katsuie was defeated at the Battle of Shizugatake, and Kazumasu suffered defeat at Kameyama. Nobutaka ultimately surrendered.
Following his defeat, Nobutaka was confined to Daimidoji at Noma in Owari Province, the site where Minamoto no Yoshitomo had been assassinated centuries earlier. Under pressure from Hideyoshi and Nobukatsu, Nobutaka committed suicide in 1583. Historical records cite either June 19 or June 21 as the date of his death.

Yasumasa was the second son of Sakakibara Nagamasa and was born in Ueno in Mikawa Province. From a young age, he began serving Tokugawa Ieyasu and eventually rose to the position of one of his most trusted generals. His wife was the daughter of Osuga Yasutaka. Ieyasu first noticed the young Yasumasa during the suppression of the Ikkō-ikki uprising in Mikawa in 1564. Thanks to his demonstrated abilities, Yasumasa was granted the privilege of using the character “yasu”—the second character of Ieyasu’s own name—in his own. Although he was the second child in his family, he became his father’s heir, though the exact reasons for this remain unknown.

The son of Ouchi Masahiro, he governed from his residence in Yamaguchi in the province of Suo. In 1499, Yoshioki gave refuge to Shogun Ashikaga Yoshitane, who had been driven out of Kyoto by Hosokawa Masamoto. Shogun Yoshizumi, Masamoto’s protégé, ordered the lords of Kyushu to unite their forces against Yoshioki; however, they did not dare to do so, fearing the power of a man who by that time controlled six provinces. Having gathered a substantial army, Yoshioki marched from his native Suo toward Kyoto in order to restore Shogun Yoshitane to power.
