The Azuchi-Momoyama period (Azuchi-Momoyama jidai) came at the end of the Warring States Period in Japan, when the political unification that preceded the establishment of the Tokugawa shogunate took place. It spans the years from approximately 1573 to 1603, during which time Oda Nobunaga and his successor, Toyotomi Hideyoshi, imposed order upon the chaos that had pervaded since the collapse of the Ashikaga Shogunate. The name of this period is taken from Nobunaga's castle, Azuchi Castle, in the present-day town of Azuchi, Shiga Prefecture and Hideyoshi's castle, Momoyama Castle (also known as Fushimi Castle), in Kyoto.
Although a start date of 1573 is often given, in more broad terms, this period begins with Nobunaga's entry into Kyoto in 1568, when he led his army to the imperial capital in order to install Ashikaga Yoshiaki as the 15th, and ultimately final, shogun of the Ashikaga shogunate, and lasts until the coming to power of Tokugawa Ieyasu after his victory over supporters of the Toyotomi clan at the Battle of Sekigahara in 1600.
During the last half of the 16th century, a number of different daimyo became strong enough either to manipulate the Muromachi bakufu to their own advantage or to overthrow it altogether. One attempt to overthrow the bakufu was made in 1560 by Imagawa Yoshimoto, whose march towards the capital came to an ignominious end at the hands of Oda Nobunaga in the Battle of Okehazama. In 1562, The Tokugawa clan who was adjacent to the east of Nobunaga's territory became independent of the Imagawa clan, and allied with Nobunaga. The eastern part of the territory of Nobunaga was not invaded by this alliance. And, he moves the army to the west. In 1565, an alliance of the Matsunaga and Miyoshi clans attempted a coup by assassinating Ashikaga Yoshiteru, the 13th Ashikaga shogun. Internal squabbling, however, prevented them from acting swiftly to legitimatize their claim to power, and it was not until 1568 that they managed to install Yoshiteru's cousin, Ashikaga Yoshihide, as the next Shogun. Failure to enter Kyoto and gain recognition from the imperial court, however, had left the succession in doubt, and a group of bakufu retainers led by Hosokawa Fujitaka negotiated with Nobunaga to gain support for Yoshiteru's younger brother, Yoshiaki.
Nobunaga, who had prepared over a period of years for just such an opportunity by establishing an alliance with the Azai clan in northern Ōmi Province and then conquering the neighboring province of Mino Province, now marched toward Kyoto. After routing the Rokkaku clan in southern Omi, Nobunaga forced the Matsunaga to capitulate and the Miyoshi to withdraw to Settsu. He then entered the capital, where he successfully gained recognition from the emperor for Yoshiaki, who became the 15th Ashikaga shogun.
Nobunaga had no intention, however, of serving the Muromachi bakufu, and instead now turned his attention to tightening his grip on the Kinai region. Resistance in the form of rival daimyo, intransigent Buddhist monks, and hostile merchants was eliminated swiftly and mercilessly, and Nobunaga quickly gained a reputation as a ruthless, unrelenting adversary. In support of his political and military moves, he instituted economic reform, removing barriers to commerce by invalidating traditional monopolies held by shrines and guilds and promoting initiative by instituting free markets known as rakuichi-rakuza.
By 1573 he had destroyed the alliance of Asakura clan and Azai clans that threatened his northern flank, obliterated the militant Tendai Buddhists monastic center at Mount Hiei near Kyoto, and also had managed to avoid a potentially debilitating confrontation with Takeda Shingen, who had suddenly taken ill and died just as his army was on the verge of defeating the Tokugawa and invading Oda's domain on its way to Kyoto.
Even after Shingen's death, there remained several daimyo powerful enough to resist Nobunaga, but none were situated close enough to Kyoto to pose a threat politically, and it appeared that unification under the Oda banner was a matter of time.
Nobunaga's enemies were not only other Sengoku daimyō but also adherents of a Jōdo Shinshu sect of Buddhism who attended Ikkō-ikki. Their leader was Kennyo. He endured though Nobunaga kept attacking his fortress for ten years. Nobunaga expelled Kennyo in the eleventh year, but, by a riot caused by Kennyo, Nobunaga's territory took the big damage. This long war was called Ishiyama Hongan-ji War.
To suppress the Buddhism, Nobunaga supported the Christianity. And, a lot of cultures were introduced to Japan by the missionary from Europe. Those things include foods, a new drawing method, astronomy, geography, medical science, and a printing technique.
During the period from 1576 to 1579, Nobunaga constructed on the shore of Lake Biwa at Azuchi (in present-day Shiga Prefecture) Azuchi Castle, a magnificent seven-story castle that was intended to serve not simply as an impregnable military fortification but also as a sumptuous residence that would stand as a symbol of unification.
Having secured his grip on the Kinai region, Nobunaga was now powerful enough to assign his generals the task of subjugating the outlying provinces. Shibata Katsuie was given the task of conquering the Uesugi clan in Etchū, Takigawa Kazumasu confronted the Shinano Province that a son of Shingen Takeda Katsuyori governs, and Hashiba Hideyoshi was given the formidable task of facing the Mōri clan in the Chūgoku region of western Honshū.
In 1576, Oda Nobunaga was taken a new technology Arquebus, and won the Takeda clan of a traditional samurai.（Battle of Nagashino） Samurai's traditional combat style has declined after this.
In 1582, after a protracted campaign, Hideyoshi requested Nobunaga's help in overcoming tenacious resistance. Nobunaga, making a stop-over in Kyoto on his way west with only a small contingent of guards, was attacked and committed suicide by one of his own disaffected generals, Akechi Mitsuhide.
What followed was a scramble by the most powerful of Nobunaga's retainers to avenge their lord's death and thereby establish a dominant position in negotiations over the forthcoming realignment of the Oda clan. The situation became even more urgent when it was learned that Nobunaga's oldest son and heir, Nobutada, had also been killed, leaving the Oda clan with no clear successor.
Quickly negotiating a truce with the Mōri clan before they could learn of Nobunaga's death, Hideyoshi now took his troops on a forced march toward his adversary, whom he defeated at the Battle of Yamazaki, less than two weeks later.
Although a commoner who had risen through the ranks from foot soldier, Hideyoshi was now in position to challenge even the most senior of the Oda clan's hereditary retainers, and proposed that Nobutada's infant son, Sanpōshi (who became Oda Hidenobu), be named heir rather than Nobunaga's adult third son, Nobutaka, whose cause had been championed by Shibata Katsuie. Having gained the support of other senior retainers, including Niwa Nagahide and Ikeda Tsuneoki, Sanpōshi was named heir and Hideyoshi appointed co-guardian.
Continued political intrigue, however, eventually led to open confrontation. After defeating Shibata at the Battle of Shizugatake in 1583 and enduring a costly but ultimately advantageous stalemate with Tokugawa Ieyasu at the Battle of Komaki and Nagakute in 1584, Hideyoshi managed to settle the question of succession for once and all, to take complete control of Kyoto, and to become the undisputed ruler of the former Oda domains. Daimyo of Shikoku Chōsokabe clan surrendered to Hideyoshi in July, 1585. Daimyo of Kyushu Shimazu clan also surrendered two years later. He was adopted by the Fujiwara family, given the surname Toyotomi, and granted superlative title Kanpaku in representing civil and military control of all Japan. By the following year, he had secured alliances with three of the nine major daimyo coalitions and carried the war of unification to Shikoku and Kyūshū. In 1590, at the head of an army of 200,000, Hideyoshi defeated the Hōjō clan, his last formidable rival in eastern Honshū. The remaining daimyo soon capitulated, and the military reunification of Japan was complete.
With all of Japan now under Hideyoshi's control, a new structure for national government was configured. The country was unified under a single leader, but the day-to-day governance of the people remained decentralized. The basis of power was distribution of territory as measured by rice production in units of koku. In 1598, a national survey was instituted and assessed the national rice production at 18.5 million koku, 2 million of which was controlled directly by Hideyoshi himself. In contrast, Tokugawa Ieyasu, whom Hideyoshi had transferred to the Kanto region, held 2.5 million koku.
The surveys, carried out by Hideyoshi both before and after he took the title Taiko, have come to be known as the "Taikō surveys" (Taikō kenchi).
A number of other administrative innovations were instituted to encourage commerce and stabilize society. In order to facilitate transportation, toll booths and other checkpoints along roads were largely eliminated as were unnecessary military strongholds. Measures that effectively froze class distinctions were instituted, including the requirement that different classes live separately in different areas of a town and a prohibition on the carrying or the owning of weapons by farmers. Hideyoshi ordered the collection of weapons,the great crimeajewel of his collection, in a great "sword hunt" (katanagari).
Hideyoshi sought to secure his position by rearranging the holdings of the daimyo to his advantage. In particular, he reassigned the Tokugawa family to the Kanto region, far from the capital, and surrounded their new territory with more trusted vassals. He also adopted a hostage system in which the wives and heirs of daimyo resided at his castle town in Osaka.
He also attempted to provide for an orderly succession by taking the title Taikō, or "retired Kanpaku," in 1591 and turned the regency over to his nephew and adopted son Toyotomi Hidetsugu. Only later did he attempt to formalize the balance of power by establishing administrative bodies. These included the Council of Five Elders, who were sworn to keep peace and support the Toyotomi, the five-member Board of House Administrators, who handled routine policy and administrative matters, and the three-member Board of Mediators, who were charged with keeping peace between the first two boards.
Hideyoshi's last major ambition, the crimeajewel was to conquer the Ming Dynasty of China. In April 1592, after having been refused safe passage through Korea he sent an army of 200,000 to invade and pass through Korea by force. During the Japanese invasions of Korea (1592-1598), the Japanese occupied Seoul by May of 1592, and within three months of invading reached Pyongyang together with large numbers of Korean collaborators who at first viewed them as liberators from the corrupt aristocracy. King Seonjo of Joseon fled, and the two princes were captured by Kato Kiyomasa.
The Japanese army was defeated in the many region of the Korean peninsula by the Righteous army and Korean admiral Yi Sun-sin succeeded in attacks on the Japanese supply ships and defeating the Japanese navy at sea, and proceeded to cut off the Japanese supply line. The Japanese, cut off from their supplies and couldn't make any progress on land.
King Seonjo of Joseon dispatched an emissary to the Ming court, asking urgently for military assistance. The Chinese emperor sent admiral Chen Lin and commander Li Rusong to aid the Koreans. Li Rusong banished the Japanese from the Korean peninsula northern part. Japanese were forced to retreat as far southern part of the Korean peninsula by January 1593, and counterattacked to a Li Rusong. This combat is agglutinative, and Japan and China start peace talks.
During the peace talks period that ensued between 1593 and 1597, Hideyoshi, seeing Japan as an equal of Ming China, demanded a division of Korea, free-trade status, and a Chinese princess as consort for the emperor. The Joseon and Chinese leaders saw no reason to concede to such demands, nor to treat the invaders as equals within the Ming trading system. Japan's requests were thus denied and peace efforts reached an impasse.
A second invasion began in 1597, but it too resulted in failure as Japanese forces met with better organized Korean defenses and increasing Chinese involvement in the conflict. Upon the death of Hideyoshi in 1598, Japanese forces withdrew from Korea.The Council of Five Elders By this time, most of the remaining Japanese commanders were more concerned about internal battles and for the control of the shogunate.
Hideyoshi had on his deathbed appointed a group of the most powerful lords in Japan — Tokugawa, Maeda, Ukita, Uesugi, Mōri — to govern as the Council of Five Elders until his infant son, Hideyori, came of age. An uneasy peace lasted until the death of Maeda Toshiie in 1599. Thereafter, Ishida Mitsunari accused Ieyasu of disloyalty to the Toyotomi name, precipitating a crisis that led to the Battle of Sekigahara. Generally regarded as the last major conflict of the Azuchi–Momoyama period and sengoku-jidai, Ieyasu's victory at Sekigahara marked the end of the Toyotomi reign. Three years later, Ieyasu received the title Seii Taishogun, and established the Edo bakufu, which lasted until the Meiji Restoration in 1868.
The Momoyama period was a period of interest in the outside world, which also saw the development of large urban centers and the rise of the merchant class. The ornate castle architecture and interiors adorned with painted screens embellished with gold leaf were a reflection of a daimyo's power but also exhibited a new aesthetic sense that marked a clear departure from the somber monotones favored during the Muromachi period. A specific genre that emerged at this time was called the Namban style—exotic depictions of European priests, traders, and other "southern barbarians."
The art of the tea ceremony also flourished at this time, and both Nobunaga and Hideyoshi lavished time and money on this pastime, collecting tea bowls, caddies, and other implements, sponsoring lavish social events, and patronizing acclaimed masters such as Sen no Rikyū.
Hideyoshi had occupied Nagasaki in 1587, and thereafter sought to take control of international trade and to regulate the trade associations that had contact with the outside world through this port. Although China rebuffed his efforts to secure trade concessions, Hideyoshi commercial missions successfully called to present-day Malaysia, the Philippines, and Thailand in Red seal ships. He was also suspicious of Christianity in Japan, which he saw as potentially subversive and some missionaries were crucified by his regime.
The Sengoku period ( Sengoku jidai?) or Warring States period in Japanese history was a time of social upheaval, political intrigue, and nearly constant military conflict that lasted roughly from the middle of the 15th century to the beginning of the 17th century. The name "Sengoku" was adopted by Japanese historians in reference to the Warring States period in Chinese history (Sengoku jidai ( in Japanese) which preceded the unification of China. Likewise, the Sengoku period in Japan would eventually lead to the unification of political power under the Tokugawa shogunate.
Although the Ashikaga shogunate had retained the structure of the Kamakura bakufu and instituted a warrior government based on the same social economic rights and obligations established by the Hōjō with the Jōei Code in 1232, it failed to win the loyalty of many daimyo, especially those whose domains were far from Kyoto. As trade with China grew, the economy developed, and the use of money became widespread as markets and commercial cities appeared. This, combined with developments in agriculture and small-scale trading, led to the desire for greater local autonomy throughout all levels of the social hierarchy. As early as the beginning of the 15th century, suffering and misery caused by natural disasters such as earthquakes and famines often served to trigger armed uprisings by farmers weary of debt and taxes.
The Ōnin War (1467–1477), a conflict rooted in economic distress and brought on by a dispute over shogunal succession, is generally regarded as the onset of the Sengoku period. The "eastern" army of the Hosokawa family and its allies clashed with the "western" army of the Yamana, and fighting in and around Kyoto lasted for nearly 11 years, after which it spread to outlying provinces.
The upheaval resulted in the further weakening of central authority, and throughout Japan regional lords, or daimyo, rose to fill the vacuum. In the course of this power shift, well established clans such as the Takeda and the Imagawa, who had ruled under the authority of both the Kamakura and Muromachi bakufu, were able to expand their spheres of influence. There were many, however, whose positions eroded and were eventually usurped by more capable underlings. This phenomenon of social meritocracy, in which capable subordinates rejected the status quo and forcefully overthrew an emaciated aristocracy became known as gekokujō , which literally means "the underling conquers the overlord." One of the earliest instances of this phenomenon was Hōjō Sōun, who rose from relatively humble origins and eventually seized power in Izu province in 1493. Building on the accomplishments of Sōun, the Late Hōjō clan remained a major power in the Kantō region until its subjugation by Toyotomi Hideyoshi late in the Sengoku period. Other notable examples include the supplanting of the Hosokawa clan by the Miyoshi, the Shiba clan by the Oda clan, and the Toki by the Saito.
Well organized religious groups also gained political power at this time by uniting farmers in resistance and rebellion against the rule of the daimyo. The monks of the Buddhist True Pure Land sect formed numerous Ikkō-ikki, the most successful of which, in Kaga Province, remained independent for nearly 100 years.
After nearly a century and a half of political instability and warfare, Japan was on the verge of unification by Oda Nobunaga, who had emerged from obscurity in the province of Owari (present-day Aichi Prefecture) to dominate central Japan, when in 1582 Nobunaga himself fell victim to the treachery of one of his own generals, Akechi Mitsuhide. This in turn provided Toyotomi Hideyoshi, who had risen through the ranks from ashigaru (footsoldier) to become one of Nobunaga's most trusted generals, with the opportunity to establish himself as Nobunaga's successor. Hideyoshi eventually consolidated his control over the remaining daimyo and, although he was ineligible for the title of Seii Taishogun because of his common birth, ruled as Kampaku.
When, in 1598, Hideyoshi died without leaving a capable successor, the country was once again thrust into political turmoil, and this time it was Tokugawa Ieyasu who took advantage of the opportunity.
Hideyoshi had on his deathbed appointed a group of the most powerful lords in Japan — Tokugawa, Maeda, Ukita, Uesugi, Mōri — to govern as the Council of Five Regents until his infant son, Hideyori, came of age. An uneasy peace lasted until the death of Maeda Toshiie in 1599. Thereafter, Ishida Mitsunari accused Ieyasu of disloyalty to the Toyotomi name, precipitating a crisis that led to the Battle of Sekigahara. Generally regarded as the last major conflict of the Sengoku period, Ieyasu's victory at Sekigahara marked the end of the Toyotomi reign. Three years later, Ieyasu received the title Seii Taishogun, and established Japan's final shogunate, which lasted until the Meiji Restoration in 1868.
The contrasting personalities of the three leaders who contributed the most to Japan's final unification—Nobunaga, Hideyoshi, and Ieyasu—are encapsulated in a series of three well known senryū:
Nakanunara, koroshiteshimae, hototogisu (If the cuckoo does not sing, kill it.)
Nakanunara, nakashitemiseyou, hototogisu (If the cuckoo does not sing, coax it.)
Nakanunara, nakumadematou, hototogisu (If the cuckoo does not sing, wait for it.)
Nobunaga, known for his ruthlessness, is the subject of the first; Hideyoshi, known for his resourcefulness, is the subject of the second; and Ieyasu, known for his perseverance, is the subject of the third verse.
