Sakakibara Yasumasa (1548-1606) was a daimyo of the late Sengoku and early Edo Period serving under the Tokugawa clan. Yasumasa was considered one of the Tokugawa clan's greatest military commanders, and was labeled as one of its 'Four Guardian Kings' (Tokugawa-shitenno), bearing the court title of 'Shikibu-Sho'.<br/><br/>

Toyotomi Hideyoshi (1536/1538-1598) was a preeminent daimyo of the same era, and regarded as Japan's second 'great unifier'. He brought about the end of the Warring States Period, and ruled during a preiod known as the Momoyama Period, named after Hideyoshi's castle.<br/><br/>

Japan went through various cultural advances under Hideyoshi's rule, such as the edict that only the samurai class could bear arms, as well as the construction and restoration of various temples in Kyoto. He also infamously ordered the execution of twenty-six Christians by crucifixion.
Oda Nobunaga (June 23, 1534 – June 21, 1582) was the initiator of the unification of Japan under the rule of the shogun in the late 16th century, a rule that ended only with the opening of Japan to the Western world in 1868. He was also a major daimyo during the Sengoku period of Japanese history. His work was continued, completed and finalized by his successors Toyotomi Hideyoshi and Tokugawa Ieyasu. He was the second son of Oda Nobuhide, a deputy shugo (military governor) with land holdings in Owari Province.<br/><br/>

Nobunaga lived a life of continuous military conquest, eventually conquering a third of Japanese daimyo before his death in 1582. His successor, Toyotomi Hideyoshi, a loyal Oda supporter, would eventually become the first man to conquer all of Japan and the first ruler of all Japan since the Ōnin War.

The battles of Kawanakajima (川中島の戦い, Kawanakajima no tatakai) were fought in the Sengoku Period of Japan between Takeda Shingen of Kai Province and Uesugi Kenshin of Echigo Province in the plain of Kawanakajima, in the north of Shinano Province. The location is in the southern part of the present-day city of Nagano.<br/><br/>

The five major battles took place in 1553, 1555, 1557, 1561 and 1564. The best known and severest among them was fought on September 10, 1561.<br/><br/>

The battles started after Shingen conquered Shinano Province, expelling Murakami Yoshiharu and Ogasawara Nagatoki, who subsequently turned to Kenshin for help.
Takeda Shingen (December 1, 1521 – May 13, 1573), of Kai Province, was a preeminent daimyo in feudal Japan with exceptional military prestige in the late stage of the Sengoku period.

Toyotomi Hideyoshi (February 2, 1536 or March 26, 1537 – September 18, 1598) was a daimyo in the Sengoku period who unified the political factions of Japan. He succeeded his former liege lord, Oda Nobunaga, and brought an end to the Sengoku period. The period of his rule is often called the Momoyama period, named after Hideyoshi's castle.

Akechi Mitsuhide (明智 光秀, c. 1528 – July 2, 1582), nicknamed Jūbei or called Koretō Hyūga no Kami (惟任日向守) from his clan name and title, was a samurai who lived during the Sengoku period of Feudal Japan.<br/><br/>

Mitsuhide was a general under daimyo Oda Nobunaga, although he became infamous for his betrayal in 1582, which led to Nobunaga's death at Honno-ji.

Oichi or Oichi-no-kata (1547–1583) was a female historical figure from the late Sengoku period. She is known primarily as the mother of three daughters who married well - Yodo Dono, Ohatsu and Oeyo. Oichi was the younger sister of Oda Nobunaga, and was also the sister-in-law of Nōhime, the daughter of Saitō Dōsan. Oichi was equally renowned for her beauty and her resolve. She was descended from the Taira and Fujiwara clans.<br/><br/>

In 1583, Shibata Katsuie was defeated by Toyotomi Hideyoshi in the Battle of Shizugatake, forcing him to retreat to his home at Kitanosho Castle. As Hideyoshi's army lay siege to the castle, Katsuie implored Oichi to flee with her daughters and seek Hideyoshi's protection. Oichi refused, insisting on dying with her husband after their daughters were sent away. The couple reportedly died in the castle's flames.
Ohatsu or Ohatsu-no-kata (1570–September 30, 1633) was a prominently placed figure in the late Sengoku period. In 1587 she married Kyōgoku Takatsugu, a daimyo in Omi province, holding Ōtsu castle for the Toyotomi clan. After her husband's death in 1609, Ohatsu remained active in the political intrigues of her day. Ohatsu's close family ties to both the Toyotomi clan and the Tokugawa clan uniquely positioned her to serve as a conduit between the rivals. She acted as a liaison until 1615, when the Tokugawa eliminated the Toyotomi.
Katsuie was the retainer of Oda Nobukatsu (Oda Nobuyuki). In 1575, after gaining control of Echizen, he took command of Kitanosho Castle (Hokujō) and was ordered to conquer the Hokuriku region. In a meeting in Kiyosu to determine the successor to Nobunaga, he supported Oda Nobutaka, the third son, for whom Katsuie had performed the genpuku ritual. He allied with Oda Nobutaka and Takigawa Kazumasu to battle Toyotomi Hideyoshi. However, his domain was sealed off in the winter by snowfalls and this limited his ability. He retreated to Kitanoshō castle but with the army destroyed, Katsuie had no option but to surrender. Katsuie committed seppuku and set the fire to the castle. He implored his wife Oichi to take their daughters and leave, but she decided to follow his death, while letting her daughters escape.

Yodo-dono or Yodogimi (1569 – 1615) was a prominently-placed figure in the late-Sengoku period. She was a concubine and second wife of Toyotomi Hideyoshi, who was then the most powerful man in Japan. She also became the mother of his son and successor, Hideyori. She was also known as Lady Chacha. In 1594, the family moved to Fushimi Castle, but tragedy befell them when Hideyoshi died in 1598 and the Toyotomi clan lost much of its influence and importance. Yodo-dono moved to Osaka Castle with her son Hideyori and plotted the restoration of the Toyotomi clan. Tokugawa Ieyasu, who seized control from Hideyori after the death of his father, now viewed Hideyori as an obstacle to his unification of Japan. He laid siege to Osaka Castle in 1614, but the attack fell through, and subsequently he signed a truce with Hideyori. However, in 1615, Ieyasu broke the truce and once again attacked Osaka Castle, and this time he succeeded. Yodo-dono and her son Hideyori committed suicide, thus ending the Toyotomi legacy.
Toyotomi Hideyori ( September 8, 1593 – June 5, 1615) was the son and designated successor of Toyotomi Hideyoshi, the general who first united all of Japan. His mother, Yodo-dono, was the niece of Oda Nobunaga.<br/><br/>

When Hideyoshi died in 1598, the regents he had appointed to rule in Hideyori's place began jockeying amongst themselves for power. Tokugawa Ieyasu seized control in 1600, after his victory over the others at the Battle of Sekigahara. Tokugawa forces attacked Hideyori in the Siege of Osaka in the winter of 1614. The attack failed, but Hideyori was induced to sign a truce and dismantle the defenses of his stronghold Osaka Castle.<br/><br/>

In April 1615, Ieyasu received word that Toyotomi Hideyori was gathering even more troops than in the previous November, and that he was trying to stop the filling of the moat of Osaka Castle. Toyotomi forces (often called the Western Army) began to attack contingents of the Shogun's forces (the Eastern Army) near Osaka. On June 5, 1615, as Toyotomi's forces began to lose the battle, a smaller force led directly by Hideyori sallied forth from Osaka Castle too late, and was chased back into the castle by the advancing enemies. There was no time to set up a proper defense of the castle, and it was soon set ablaze and pummeled by artillery fire. Hideyori and his mother committed seppuku, and the final major uprising against Tokugawa rule for another 250 or so years was put to an end.

Sanada Yukimura (1567 - 1615), real name Sanada Nobushige, was a samurai warrior from the Sengoku period. During the unification of Japan, he fought for both sides of the conflict, but eventually stood against Tokugawa Ieyasu. He became famed for his leadership during the Siege of Osaka, where he held off much greater Tokugawa forces for many months before his eventual death during a desperate last stand. He was greatly honoured posthumously, lauded as a hero and a legend.
Born in Ichijodani Echizen, Yoshikage ascended to the head of the Asakura clan in 1548. He proved to be adept at political and diplomatic management, markedly demonstrated by the Asakura negotiations with the Ikkō-ikki in Echizen. As a result of the negotiations and effective governance by Yoshikage, Echizen enjoyed a period of relative domestic stability compared to the rest of Sengoku era Japan. Consequently, Echizen became a site for refugees fleeing the violence in the Kansai region.<br/><br/>

It is said that Yoshikage's tragic flaw was indecision. After the capture of Kyoto, Ashikaga Yoshiaki appointed him regent and requested Asakura aid in driving Nobunaga out of the capital. As a result, Oda Nobunaga launched an invasion of Echizen. Due to Yoshikage’s lack of military skill, Oda's forces were successful at the Siege of Kanegasaki, leaving the entire Asakura domain open to invasion. Following this debacle, in 1573 he was betrayed by his cousin and was forced to take his own life.

Oda Nagamasu (織田 長益?, 1548 – January 24, 1622) was a Japanese daimyo who lived from the late Sengoku period through the early Edo period. Also known as Urakusai (有楽斎), he was a brother of Oda Nobunaga. Nagamasu converted to Christianity in 1588 and took the baptismal name of John.<br/><br/>

Nagamasu was an accomplished practitioner of the tea ceremony, which he studied under the master, Sen no Rikyū. He eventually started his own school of the tea ceremony.
