Oda Nabunaga

Oda Nobunaga was the first of the great Three Unifiers who rose to power in the late Sengoku Period, uniting much of Japan under his rule, and setting the stage for the eventual end of the wars and chaos which had dominated the archipelago for more than 100 years.

Nobunaga is known for numerous military, political, economic, and cultural activities, accomplishments and innovations, including his innovative use of firearms and victory at the battle of Nagashino in 1575; his abolition of guilds and customs barriers, leading to significant economic integration; and the construction of Azuchi castle, the model for Japanese castles in the mode most well-known today.

His death in 1582 in the Honnoji Incident led to his retainer Toyotomi Hideyoshi rising to power as hegemon over the archipelago.

son of Oda Nobuhide (1508? –1549), a minor lord whose family once served the Shiba  shugo. Nobuhide was a skilled warrior, and spent much of his time fighting the samurai of Mikawa and Mino. He also had enemies closer to home - the Oda were divided into two separate camps, with both vying for control of Owari's eight districts. Nobuhide's branch, of which he was one of three elders, was based at Kiyosu castle. The rival branch was to the north, in Iwakura castle.

Many of Nobuhide's battles were fought in Mikawa, against the Matsudaira and the Imagawa clan. The latter were old and prestigious, rulers of Suruga and overlords of Totomi. The Matsudaira were as obscure as the Oda, and while not as splintered politically, they were slowly coming under the Imagawa's influence. The decade leading up to 1548 was dominated along the Mikawa-Owari border by the contention of three men - Oda Nobuhide, Matsudaira Hirotada, and Imagawa Yoshimoto. In 1542, Imagawa, supported by the Matsudaira, marched as far west as the Owari border, and was met by Oda Nobuhide and his younger brother Tsuda Nobumitsu at Azukizaka. In this bitter fight, the Oda emerged victorious, but not decisively. In 1548 Nobuhide attempted to arrange the defection of a certain Matsudaira Tadamoto of Mikawa away from Hirotada. Tadamoto, however, ended up being killed in the attempt, and Oda launched an attack on Okazaki, evidently to make up for the disappointment. Matsudaira Hirotada thus found himself in difficult straights, and called on Imagawa for assistance. Yoshimoto replied that he would be happy to help - so long as Hirotada was willing to send along his young son as a hostage. Hirotada had little choice, and shipped off 6-year old Takechiyo (the future Tokugawa Ieyasu) westward. En-route to Suruga, unfortunately, Oda loyalists intercepted the hostage party and made off with Takechiyo, taking the child to Nobuhide. Nobuhide immediately made use of his new card and demanded that Hirotada give up Okazaki in return for his son's life. Hirotada wisely refused, and Nobuhide, his bluff called, did no harm to the boy. Later in 1548, Imagawa and Oda met again in battle, and this time the Imagawa came out the winner. The following year Nobuhide died, leaving an Oda clan divided in every possible way.

Anxious to capitalize on the death of his rival, Imagawa Yoshimoto sent his uncle, the talented monk-general Sessai Choro, to attack Nobuhide's heir, Nobuhiro. Sessai besieged Nobuhiro in Anjo castle, and sent word to Nobunaga that unless he wished to see his elder brother made to commit suicide, he would have to send back Takechiyo. Nobunaga could hardly refuse, and so Takechiyo ended up in Suruga, even though his father Hirotada had passed away that same year.

The progress of the next three years is hazy. By 1551, however, Nobunaga was the leader of his faction of the Oda and master of Kiyosu. His principal enemy (beyond his own family) was his father's nemesis, the Imagawa. Nobunaga's northern borders (not counting the area of Mino controlled by the Iwakura Oda) were more or less secured, at least: before his death, Nobuhide had arranged for the marriage of Nobunaga to Saito Dosan's daughter. Saito Toshimasa  (Dosan) (1494-1556) was a colorful figure, a former oil-merchant (if tradition is to be believed) who supplanted the Toki family of Mino.

As just noted, Saito Yoshitatsu was the new lord of Mino, having killed Dosan at the Battle of Nagaragawa (1556), and he was no friend to the Oda. The Oda's forts in Mino were quickly reduced, and Nobunaga's attempts to make in-roads in that province were turned back. At the same time, Imagawa Yoshimoto was knocking on Owari's southeastern door, having all but absorbed Mikawa and the Matsudaira clan. Imagawa's army had lost some of it's potency with the death of Sessai Choro in 1555 but Yoshimoto could call on the services of a young and skillful ally – Matsudaira Motoyasu, a man whose fate would prove inter-twined with that of Nobunaga. In 1558, Motoyasu fought his first battle - at Nobunaga's expense. Oda had recently bribed Terabe castle away from the Matsudaira, and Motoyasu, with the Imagawa's blessing, took it back, defeating a relief force sent by Nobunaga. The next year, Imagawa did a little horse-trading of his own, and lured Otaka castle away from the Oda. Nobunaga was furious, and had the fort surrounded. Soon, the garrison began to run out of food, and to lead a relief effort, Imagawa sent Matsudaira Motoyasu. Using a crafty bit of diversion, Motoyasu successfully provisioned Otaka - much to Nobunaga's chagrin.

Okehazama, 1560

The following year, 1560, Imagawa Yoshimoto  decided to make a decisive move to the west. His aim was to drive along the Tokaido coast, brushing aside the Oda and any who did not submit to the Imagawa army with the ultimate goal of occupying Kyoto. To this end Yoshimoto gathered perhaps 20,000 to 25,000 men from Suruga, Totomi, and Mikawa in June, leaving his son Ujizane to run things while he was off conquering. He included Matsudaira Motoyasu in the invasion force, and dispatched the Mikawa samurai to reduce the fort of Marume. Meanwhile, the rest of the Imagawa host crossed in Owari and assaulted Washizu castle. The commanders of the besieged forts (Sakuma Morishige and Oda Genba) managed to get off letters of warning to Nobunaga in Kiyosu, and his retainers were divided on what course of action to take. Given the obvious disparity in numbers, it seemed logical to adopt a defensive posture, or even to capitulate. Nobunaga was for fighting. With all the brash and unpredictable élan he was to show throughout his career, he ordered a conch shell blown and the garrison of Kiyosu made ready for battle.

The next morning, while Marume and Washizu were going up in flames, Nobunaga led a handful of men out of the castle and headed in the direction of Imagawa's army. Along the way he was joined by enough ashigaru and samurai to make an attack credible-if not particularly wise. At ten to one odds, Nobunaga's chances seemed slim at best, although the priests at the Atsuta Shrine that he stopped at to pray for victory commented on how calm he appeared.

Meanwhile, Imagawa was celebrating the course of his campaign so far. Encamped in the Dengakuhazama gorge, Imagawa's army rested and enjoyed sake, their leader engrossed in the viewing of the heads taken at Marume and Washizu. Nobunaga, paused near the Imagawa's Narumi castle, learned of the Imagawa's location from scouts, and played a stratagem. He had battle flags hoisted up from behind a hill, presenting the image to the Imagawa stationed inside Narumi that the Oda were resting nearby. In fact, Nobunaga slipped his men quietly away, leading them in the direction of the Dengakuhazama. At this critical point, a bit of good luck went Nobunaga's way. A summer thunderstorm broiled over and let loose with a torrential downpour, enabling Nobunaga to sneak up quite close to the Imagawa's position. When the rains abated, he gave the order to attack.

Such was the suddenness and ferocity of the attack; Imagawa assumed that a fight had broken out among his own men. His misconception was quickly righted by the appearance of Oda spearmen who succeeded in taking the head of the lord of Suruga. Nobunaga's surprise attack worked beautifully, and once word spread of Yoshimoto's demise, the Imagawa army fled, utterly defeated. Matsudaira Motoyasu, resting his men in Marume, heard of the defeat and thought it best to return to Mikawa forthwith.

Nobunaga's Move To Regional Power, 1561-1570

In 1561, Saito Yoshitatsu, who had continued to fend off advances by the Oda, passed away, probably of leprosy. This left his son, Tatsuoki, in command and Nobunaga was quick to take advantage of the new lord's weak character. By bribing away key Saito generals, Nobunaga was able to weaken the defenses of Mino and in 1567 he attacked Inabayama, the headquarters of the Saito clan. According to tradition, the hill-top castle was brought down by Hashiba (Toyotomi) Hideyoshi, although this valuable Oda retainer does not begin appearing in written records until around 1576.

The following year, Nobunaga moved his capital to Inabayama and renamed the castle Gifu. Everything about the move was auspicious, and made possible by two alliances - one to Matsudaira Motoyasu, and another to Takeda Shingen of Kai and Shinano. The name Gifu was taken from the castle from which King Wu of Zhou (or Wu Wang), ruler of the Zhou Dynasty, had set out in the 11th or 12th century BCE to unify China. Emperor Ôgimachi sent a letter of congratulations and Nobunaga adopted the motto Tenka Fubu, or 'the realm covered in military glory' (or, alternatively, 'The nation under one sword").

Nobunaga's ambition was given a powerful stimulant with the arrival of Ashikaga Yoshiaki  at Gifu in 1567. The brother of the late shogun, Ashikaga Yoshiteru, murdered in 1565, Yoshiaki had spent the intervening years seeking out a patron. Yoshiteru's assassins - the Miyoshi and Matsunaga clans - had seen fit to legitimize their domination of Kyoto politics by naming the 2-year old Ashikaga Yoshihide as Yoshiteru's successor. When Yoshiaki heard the news, he gave up a Buddhist priesthood and fled with Hosokawa Fujitaka, both out of fear for his own life and in the hopes he would find a warlord strong enough to set things right in Kyoto. That he was the logical choice to follow Yoshiteru was clear…finding a Daimyo that would do something about it proved difficult. In his search, he approached the Takeda of Wakasa (not to be confused with the Takeda of Kai), the Uesugi of Echigo, and the Asakura of Echizen. The last seemed the most promising, in terms of military strength relative to a proximity to the capital, and indeed, Asakura Yoshikage promised to help. But Yoshikage stalled and in the end admitted that he was powerless to assist Yoshiaki's nomadic party.

Then Yoshiaki turned to Oda Nobunaga, who fairly jumped at the opportunity. In fact, he had expressed a desire in late 1565 to do just what Yoshiaki was asking, and it may be that Yoshiaki had been leery of approaching this young upstart to begin with. Uesugi and Asakura, after all, were names that carried quite a bit of prestige along with them. But, by 1567, Yoshiaki had evidently decided that beggars couldn't be choosers.

In 1568 Nobunaga's army marched westward in Yoshiaki's name, brushing aside the Rokkaku of southern Omi and putting to flight Miyoshi and Matsunaga. Matsunaga Hisahide  promptly submitted (for which he was confirmed Daimyo of Yamato) while the Miyoshi withdrew to Settsu. In the ninth month Nobunaga entered Kyoto and within three weeks Yoshiaki was installed as the fifteenth Ashikaga shogun with the approval of Emperor Ôgimachi. The mutually beneficial relationship of Yoshiaki and Nobunaga had thus far borne sweet fruit. In time, it would grow quite sour, foreshadowed by Nobunaga's refusal to accept the position of Kanrei, or deputy shogun, even when the Emperor himself requested he do so in 1569. Nobunaga seemed determined to exist in a sort of political limbo, and expressed little interest in any orthodox rank or titles, including, as we shall see, that of shogun. That Nobunaga was the real ruler in Kyoto was the only part of the equation that lacked any sort of ambiguity.

Resistance, 1570-1573

It was hardly surprising that the Daimyo who lived outside Nobunaga's sphere of influence would become quite agitated by the developments in Kyoto. Naturally, upheaval in Kyoto was nothing new - but Nobunaga was. He was quite unlike any of the various Miyoshi, Hosokawa, or Hatakeyama contenders of the past. Those lords, the Hosokawa Sumimoto's and Miyoshi Motonaga's of 1500-1565, had struggled for personal gain and prestige. Nobunaga seemed different. Certainly, he aimed for personal gain and prestige as well, but the sort of gain he desired was most different. By 1568, it is safe to say that Nobunaga aimed to rule all of Japan. Of course, this particular wish was hardly unique among the Daimyo - in point of fact, it is quite misleading to say that Nobunaga somehow possessed a vision denied his contemporaries. Rather, Nobunaga was in the right place at the right time and presented with the right window. The other great warlords of his day (some arguably greater as men go), Mori Motonari, Takeda Shingen, Uesugi Kenshin, and Hojo Ujiyasu  were all far removed from the capital, and in the case of the last three, unable to move due to the ambitions of their neighbors. The key was location. By taking Kyoto, Nobunaga positioned himself nicely in the center of Japan, which could be called the nation's 'soft under-belly'. While Nobunaga would face an implacable enemy in the Ikko-Ikki that dwelled just beyond the Kinai, the weakness of the Daimyo within that region allowed him to build, by 1573, a considerable power-base. This is not to say, of course, that Nobunaga lacked the talents usually ascribed to him. But it is perhaps inaccurate to describe him as something other than a 'sengoku Daimyo'. He was rather the ultimate expression of the 'sengoku-Daimyo'. His power was based almost solely on the point of a sword, and as he grew in power, so did his use for diplomacy diminish. He kept a tight rein on his retainers, and was ruthless to his opponents, especially those who proved especially troublesome to him. His campaigns would be long and hard-fought as his reputation for cruelty grew. Few of his enemies had any illusion about what surrender would mean.

In early 1570, Nobunaga was presented with the first real challenge to his rise. Perhaps in an effort to feel out opposition, Nobunaga had evidently pressed Yoshiaki to request all the local Daimyo to come to Kyoto and attend a certain banquet. One of those who presence was requested was none other than Asakura Yoshikage, the very Daimyo who had frittered his own chance to champion Yoshiaki. Suspecting that Nobunaga was behind the 'invitation', Yoshikage refused, an act Nobunaga declared disloyal to both the shogun and the emperor. With this pretext well in hand, Nobunaga raised an army and marched on Echizen. Initially, all went well for the attackers, with the Asakura revealing their rather lack-luster leadership abilities. By March Nobunaga, supported by Tokugawa Ieyasu (the former Matsudaira Motoyasu), had penetrated Echizen's southern approaches and was moving on Yoshikage's capital (Ichijo-no-tani). Just then, Oda received startling news. His brother-in-law, Asai Nagamasa, had suddenly switched sides and gathered troops to help the Asakura. In fact, Nagamasa's change of heart was probably not as great a surprise as one might think. The Asai and Asakura had been allies for decades, and a single marriage - even if it included the Daimyo of the clan - was not enough to nullify such a long friendship.

Nobunaga the Ruler

Prior to Ashikaga Yoshiaki’s fall in 1573, Nobunaga had not accepted any court titles. Now he accepted the prestigious rank of Kugyo. As a kugyo, Nobunaga was officially part of the ruling hierarchy and could act in state affairs. Court appointments would continue to be lavished on a near-yearly basis. He was named Gondainagon and Ukon’etaishou in 1574 and two years later was elevated to Udaijin. He showed his regard for the Court by assuring the property of the kuge  (nobles) and ordered that all land in Kyoto that had belonged to the kuge in the previous one hundred years be restored to them. Normally, statutes of limitations were considered to come into effect after a period of 20 years. On the same token, he assumed the right to settle disputes involving members of the nobility, a right he excersied by placing under temporary arrest the nobleman who had opposed his selection of the head abbot of the Kofuku-ji. During this time he handed over the official leadership of the Oda to his son Nobutada and clearly intended to carve out a political structure for his hegemony of the country. In 1577 he resigned from his ranks of Udaijin and Ukon’etaishou, pleading unfinished work in the provinces. Actually, since the policy of the court was to honor an individual based on the highest post he had achieved, Nobunaga lost no influence by so doing. According to some historians, such as Fujiki Hisashi, Nobunaga maneuvered to try to force Emperor Ogimachi  into retirement. Osamu Wakita has refuted this theory. Nobunaga adopted a son of Ogimachi’s in 1579 and in the construction of Azuchi Castle had a room set aside to receive visits from the future emperor. As Nobunaga would be the father-in-law to the emperor, he would enjoy a status along the lines of a Retired Emperor. Far from disdaining the court, Nobunaga had worked to link it directly to his vision of a united country under his rule.

Nobunaga accepted no other titles before his death, including that of shogun. Traditionally, the rank of shogun was withheld for men of Minamoto stock and Nobunaga had openly associated himself with the Taira. This is not to say that the court would not have made this appointment; in fact, such was suggested in 1582. As it was, before Nobunaga, shoguns had been the only warriors to attain the title of Kugyo. Nobunaga died before he could give an answer to the court's offer to elevate him to whatever lofty title he wanted. Yet it seems that Nobunaga was willing to honor the existing political framework of the country, at least vis-à-vis the court. What his ultimate plans were as for how he would excersise his rule over the entire country are a matter for mere speculation.
