Oda Nobunaga
Oda Nobunaga was a Japanese samurai and daimyō and one of the leading figures of the Sengoku and Azuchi-Momoyama periods. He was the Tenka-bito and regarded as the first "Great Unifier" of Japan. He is sometimes referred as the "Demon Daimyō" and "Demon King of the Sixth Heaven".
Nobunaga was an influential figure in Japanese history and is regarded as one of the three great unifiers of Japan, along with his retainers, Toyotomi Hideyoshi and Tokugawa Ieyasu. Nobunaga paved the way for the successful reigns of Hideyoshi and Ieyasu by consolidating power, as head of the very powerful Oda clan, through a series of wars against other daimyō beginning in the 1560s. The period when Nobunaga and Hideyoshi were in power is called the Azuchi–Momoyama period. The name "Azuchi–Momoyama" comes from the fact that Nobunaga's castle, Azuchi Castle, was located in Azuchi, Shiga; while Fushimi Castle, where Hideyoshi lived after his retirement, was located in Momoyama.
Nobunaga emerged as the most powerful daimyō, overthrowing the nominally ruling shogun Ashikaga Yoshiaki and dissolving the Ashikaga Shogunate in 1573. He conquered most of Honshu by 1580, and defeated the Ikkō-ikki in the 1580s. Nobunaga's rule was noted for innovative military tactics, fostering of free trade, reforms of Japan's civil government, and the start of the Momoyama historical art period, but also for the brutal suppression of those who refused to cooperate or yield to his demands.
Nobunaga committed during the Honnō-ji Incident in 1582, when his retainer Akechi Mitsuhide ambushed and trapped him in a temple in Kyoto. Nobunaga was succeeded by Toyotomi Hideyoshi, who along with Tokugawa Ieyasu completed his campaign of national unification shortly afterward.
Early life (1534–1551)
Oda Nobunaga was born on 23 June 1534 in Nagoya, Owari Province, and was the heir of Oda Nobuhide, the head of the powerful Oda clan and a deputy , and his lawful wife Dota Gozen. Nobunaga was previously thought to have been born in Nagoya Castle, but in recent years the theory that he was born in Shobata Castle has become more accepted. Nobunaga was given the childhood name of Kippōshi, and through his childhood and early teenage years became well known for his bizarre behavior.Nobunaga mostly spent his time between the age of 13 and 18 in hunting, riding, practicing archery and shooting arquebus, but also wrestling, swimming, watching sumo and visiting taverns and brothels with his friends. He also showed complete disdain for formal clothing and proper social behavior of a lord, wearing sleeveless bathrobes and short trousers tied with hemp rope in public, eating melons while riding backwards on his horse, and often dancing in female clothing in taverns, gaining the nickname The Fool of Owari.
Nobunaga was given Nagoya Castle by his father at the age of 8 and lived there for 13 years until he took Kiyosu Castle at the age of 21. He had one or two older brothers, but they were illegitimate sons. As the first legitimate son, Nobunaga was intended to succeed Nobuhide as leader of the Oda clan, and so he was separated from his mother and given special education. Four karō, Hayashi Hidesada, Hirate Masahide, Aoyama Nobumasa, and Naitō Shōsuke, were assigned to train and educate him for his future role.
Nobunaga came to manhood and took the name Oda Saburō Nobunaga in 1546. He then led the forces of the Oda clan against rival Kira and Ohama in Mikawa for his first campaign in 1547.
In 1548 or 1549, Nobuhide made peace with Saitō Dōsan, lord of Mino Province through a political marriage between his son Nobunaga and Dōsan's daughter, Nōhime. Nobunaga took Nōhime as his lawful wife, and Dōsan became Nobunaga's father-in-law. Nobunaga also became involved in government affairs at this time, gaining valuable political experience and insight.
Unification of Owari (1551–1560)
Succession crisis
In 1551, Oda Nobuhide died unexpectedly. It has been said that Nobunaga acted outrageously during his funeral, throwing ceremonial incense at the altar. Although Nobunaga was Nobuhide's legitimate heir, a succession crisis occurred when some of the Oda clan opposed him. Nobunaga assembled a force of 1,000 men and used them to intimidate and dissuade his enemies, thus preventing a serious disruption in the transfer of power.Sensing weakness, the daimyō Imagawa Yoshimoto sent an army under the command of Imagawa Sessai to lay siege to the castle at Anjō, where Oda Nobuhiro, Nobunaga's older brother, was living. To save his life, Nobunaga was compelled to turn over a hostage held by his clan at Honshōji temple, nine-year-old Matsudaira Takechiyo – later known as Tokugawa Ieyasu – an exchange that helped solidify an alliance between other rival clans. Nobuhiro, frustrated by his low standing in the Oda clan, later plotted against Nobunaga with the assistance of another rival, Saitō Yoshitatsu; Nobunaga learned of the plot but chose to forgive his brother's conduct.
In early 1552, barely several months after his father's death, one of Oda's senior retainers, and his son defected to the Imagawa clan. In response, Nobunaga attacked Noritsugu, but was defeated by Noriyoshi's forces at the Battle of Akatsuka. Nobunaga retreated and left contested lands in eastern Owari under Imagawa control.
Consolidation of clan leadership
In spring 1552, Nobunaga faced a new challenge when his uncle, Oda Nobutomo, attacked Nobunaga's domain with the support of Shiba Yoshimune, governor of Owari province. Nobunaga repelled the attack and burned the outskirts of his uncle's castle at Kiyosu to discourage further attempts. However, Nobutomo was spared any serious punishment.In 1553, Hirate Masahide, who had been one of Nobunaga's closest advisors and mentors, committed seppuku. It is generally believed that he did so to admonish Nobunaga, but the actual motive is unclear. Yoshimune tipped off Nobunaga that Nobutomo planned to assassinate him; Yoshimune was subsequently captured and put to death on Nobutomo's orders. Nobunaga mobilized his forces to blockade Kiyosu castle and set up a lengthy siege.
In 1554, Nobunaga finally achieved victory over the Imagawa clan at the Battle of Muraki Castle, reclaiming the lands he had lost to them. After securing eastern Owari, Nobunaga then turned his attention back to the siege at Kiyosu, where he eventually defeated Nobutomo and forced him to commit seppuku.
In 1556, Saitō Yoshitatsu raised an army against his father, Saitō Dōsan, who was slain in combat at the Battle of Nagara-gawa. Nobunaga set out for Oura in Mino with troops to rescue his father-in-law, but immediately withdrew upon hearing of Dōsan's death. Thereafter, Yoshitatsu usurped his father's title and became lord of Mino.
The loss of the Saitō clan's support further undermined faith in Nobunaga's leadership; key retainers such as Hayashi Hidesada, Hayashi Michitomo, and Shibata Katsuie soon turned on him. They raised an army to support his brother Nobuyuki, who was highly regarded within the Oda clan. Nobunaga defeated the rebels at the Battle of Ino, but at the plea of his birth mother, Dota Gozen, pardoned them. Despite his brother Michitomo's death in battle, Hidesada pledged his loyalty to Nobunaga and resumed serving him, while Katsuie chose to remain in Nobuyuki's service.
In 1557, however, Nobuyuki conspired with Oda Nobuyasu, lord of Iwakura Castle, to plot another rebellion. Shibata, disgusted by Nobuyuki's treachery and disloyalty, secretly warned Nobunaga. Nobunaga falsely claimed to have fallen ill and had Nobuyuki and his entourage assassinated when they came to visit him. It is said that either Kawajiri Hidetaka or Ikeda Tsuneoki carried out Nobuyuki's murder.
In 1558, Nobunaga sent an army to successfully protect Suzuki Shigeteru, lord of Terabe Castle, during the Siege of Terabe. Shigeteru had defected to Nobunaga's side from Imagawa Yoshimoto, a daimyō from Suruga Province and one of the most powerful men in the Tōkaidō region. In July 1558, he defeated his cousin, Oda Nobukata, deputy governor of northern Owari at Battle of Ukino.
By 1559, Nobunaga had captured and destroyed Iwakura Castle, eliminated all opposition within the Oda clan, and established his uncontested rule in Owari Province.
Rise to power (1560–1568)
Conflict with Imagawa
Imagawa Yoshimoto was a long-time opponent of Nobunaga's father, and had sought to expand his domain into Oda territory in Owari. In 1560, Imagawa Yoshimoto gathered an army of 25,000 men, and marched toward the capital city of Kyoto, with the pretext of aiding the frail Ashikaga Shogunate. The Matsudaira clan also joined Yoshimoto's forces.The Imagawa forces quickly overran the border fortresses of Washizu and Matsudaira forces led by Matsudaira Motoyasu took Marune Fortress from the Oda clan. Against this, the Oda clan could rally an army of only 2,000 to 3,000 men. Some of his advisors suggested that he take refuge at Kiyosu Castle and wait out a siege by the Imagawa, but Nobunaga refused, stating that "only a strong offensive policy could make up for the superior numbers of the enemy", and calmly ordered a counterattack against Yoshimoto.
Battle of Okehazama
In June 1560, Nobunaga's scouts reported that Yoshimoto was resting at the narrow gorge of Dengaku-Kazama, ideal for a surprise attack, and that the Imagawa army was celebrating their victories over the Washizu and Marune fortresses. While Yoshimoto viewed victory ahead, Nobunaga's forces marched to the Atsuta Shrine, a fortified temple overlooking the Imagawa camp. Later, Nobunaga moved to, set up a decoy army there, marched rapidly behind Yoshimoto's camp, and attacked after a terrific thunderstorm. Yoshimoto was killed by two Oda samurai. With his victory in this battle, Oda Nobunaga gained greatly in prestige, and many samurai and warlords pledged fealty to him.Kinoshita Tōkichirō, who would eventually become Toyotomi Hideyoshi, probably participated in the battle, but nothing is recorded from that time. His exploits were first recorded in the Mino Campaign.
