The Kamakura period (? Kamakura jidai, 1185-1333) is a period of Japanese history that marks the governance by the Kamakura shogunate, officially established in 1192 in Kamakura by the first sh?gun, Minamoto no Yoritomo. The period is known for the emergence of the samurai, the warrior caste, and for the establishment of feudalism in Japan.
The Kamakura period ended in 1333 with the destruction of the shogunate and the short re-establishment of imperial rule under Emperor Go-Daigo by Ashikaga Takauji, Nitta Yoshisada, and Kusunoki Masashige.
The Kamakura period marks the transition to land-based economies and a concentration of advanced military technologies in the hands of a specialized fighting class. Lords required the loyal services of vassals, who were rewarded with fiefs of their own. The fief holders exercised local military rule.
Once Minamoto Yoritomo had consolidated his power, he established a new government at his family home in Kamakura. He called his government a bakufu (, tent government), but because he was given the ancient high military title Sei-i Taish?gun by Emperor Go-Toba, the government is often referred to in Western literature as the shogunate. Yoritomo followed the Fujiwara form of house government and had an administrative board Mandokoro (), a board of retainers Samurai-dokoro (), and a board of inquiry Monch?jo (). After confiscating estates in central and western Japan, he appointed stewards for the estates and constables for the provinces. As sh?gun, Yoritomo was both the steward and the constable general. The Kamakura shogunate was not a national regime, however, and although it controlled large tracts of land, there was strong resistance to the stewards. The regime continued warfare against the Northern Fujiwara, but never brought either the north or the west under complete military control. However, the 4th leader of the Northern Fujiwara Fujiwara no Yasuhira was defeated by Yoritomo in 1189, and the 100-year-long prosperity of the north disappeared. The old court resided in Kyoto, continuing to hold the land over which it had jurisdiction, while newly organized military families were attracted to Kamakura.
Despite a strong beginning, Yoritomo failed to consolidate the leadership of his family on a lasting basis. Intrafamily contention had long existed within the Minamoto, although Yoritomo had eliminated most serious challengers to his authority. When he died suddenly in 1199, his son Minamoto no Yoriie became sh?gun and nominal head of the Minamoto, but Yoriie was unable to control the other eastern warrior families. By the early thirteenth century, a regency had been established for the sh?gun by H?j? Tokimasa--a member of the H?j? clan, a branch of the Taira that had allied itself with the Minamoto in 1180. The head of H?j? was installed as a regent for the sh?gun; the regent was termed the Shikken during the period, although later positions were created with similar power such as the Tokus? and the Rensho. Often the Shikken was also the Tokuso and Rensho. Under the H?j?, the shogun became a powerless figurehead.
With the protector of the Emperor (sh?gun) a figurehead himself, strains emerged between Kyoto and Kamakura, and in 1221 the J?ky? War broke out between the Cloistered Emperor Go-Toba and the second regent H?j? Yoshitoki. The H?j? forces easily won the war, and the imperial court was brought under the direct control of the shogunate. The sh?guns constables gained greater civil powers, and the court was obliged to seek Kamakura's approval for all of its actions. Although deprived of political power, the court retained extensive estates.
Several significant administrative achievements were made during the H?j? regency. In 1225 the third regent H?j? Yasutoki established the Council of State, providing opportunities for other military lords to exercise judicial and legislative authority at Kamakura. The H?j? regent presided over the council, which was a successful form of collective leadership. The adoption of Japan's first military code of law--the Goseibai Shikimoku--in 1232 reflected the profound transition from court to militarized society. While legal practices in Kyoto were still based on 500-year-old Confucian principles, the new code was a highly legalistic document that stressed the duties of stewards and constables, provided means for settling land disputes, and established rules governing inheritances. It was clear and concise, stipulated punishments for violators of its conditions, and parts of it remained in effect for the next 635 years.
As might be expected, the literature of the time reflected the unsettled nature of the period. The H?j?ki describes the turmoil of the period in terms of the Buddhist concepts of impermanence and the vanity of human projects. The Heike monogatari narrated the rise and fall of the Taira, replete with tales of wars and samurai deeds. A second literary mainstream was the continuation of anthologies of poetry in the Shin Kokin Wakash?, of which twenty volumes were produced between 1201 and 1205.
During the Kamakura period six new Buddhist schools (classified by scholars as "New Buddhism" or Shin Bukkyo) were founded:
During this time the pre-existing schools of Tendai, founded by Saich? (767-822), Shingon, founded by K?kai (774-835), and the great temples of Nara, collectively classified by scholars as "Old Buddhism" or Ky? Bukkyo, continued to thrive, adapt, and exert influence.:24-25 For example, all of the above six reformers had studied at the Tendai Mt. Hiei at some point in their lives.:562
Throughout the Kamakura period older Buddhist sects including Shingon, Tendai, and the Nara temple schools such as Kegon, Hoss?, Sanron, and Ritsu continued to thrive and adapt to the trend of the times.:561-563
At the start of the Kamakura period, the Mount Hiei monasteries had become politically powerful, appealing primarily to those capable of systematic study of the sect's teachings. The Shingon sect and its esoteric ritual continued to enjoy support largely from the noble families in Kyoto. However, with the increasing popularity of the new Kamakura schools, the older schools partially eclipsed as the newer "Kamakura" schools found followers among the new Kamakura government, and its samurai..
The times that gave way to the Kamakura period were marked by political and military conflict, natural disasters, and social malaise attributed to the perceived arrival of the Latter Day of the Law. The new social order of a declining aristocracy and ascending military and peasant classes resulted in new forms of religion, both indigenous:12 and Buddhist while Indian and Chinese influence continued.:556-557:11,13 Furthermore, the Sh?en manor system which had taken root in this era resulted in the increased prosperity and literacy of peasants which in turn provided more financial support for Buddhist teachers and their studies.
In the latter part of the 12th-century D?gen and Eisai traveled to China and upon their return to Japan founded, respectively, the S?t? and Rinzai schools of Zen. D?gen rejected affiliations with the secular authorities whereas Eisai actively sought them.:574 Whereas Eisai thought that Zen teachings would revitalize the Tendai school, D?gen aimed for an ineffable absolute, a pure Zen teaching that was not tied to beliefs and practices from Tendai or other orthodox schools:566 and with little guidance for leading people how to live in the secular world.:556
The final stage of Kamakura Buddhism, occurring some 50 years after H?nen, was marked by new social and political conditions as the aristocracy declined, the military class asserted new influence, and Buddhist-infused local kami practice among peasants flourished. These changing conditions created a climate that encouraged religious innovation. Nichiren and Ippen attempted at this time to create down-to-earth teachings that were rooted in the daily concerns of people.:555-556 Nichiren rejected the focus on "next-worldly" salvation such a rebirth in a Pure Land and instead aimed for "this-worldly" personal and national liberation through a simple and accessible practice.:557 Ippen emphasized a popularized form of nenbutsu recitation with an emphasis on practice rather than concentrating on an individual's underlying mental state.:559
As time evolved the distinctions between "Old" and "New" Buddhisms blurred as they formed "cultic centers" and various forms of founder worship. The medieval structures of these schools evolved into hierarchical head temple-branch temple structures with associated rituals and forms of worship. This culminated in the state-sanctioned formalized schools of the Tokugawa period.:36-37
The repulsions of two Mongol invasions were momentous events in Japanese history. In Nichiren's, Rissho Ankoku Ron, a letter to the regency, predicted this invasion years earlier. Japanese relations with China had been terminated in the mid-ninth century after the deterioration of late Tang dynasty China and the turning inward of the Heian court. Some commercial contacts were maintained with the Southern Song dynasty of China in later centuries, but Japanese pirates made the open seas dangerous. At a time when the shogunate had little interest in foreign affairs and ignored communications from China and the Goryeo kingdom, news arrived in 1268 of a new Mongol regime in Beijing. Its leader, Kublai Khan, demanded that the Japanese pay tribute to the new Yuan dynasty and threatened reprisals if they failed to do so. Unused to such threats, Kyoto raised the diplomatic counter of Japan's divine origin, rejected the Mongol demands, dismissed the Korean messengers, and started defensive preparations.
After further unsuccessful entreaties, the first Mongol invasion took place in 1274. More than 600 ships carried a combined Mongol, Chinese, and Korean force of 23,000 troops armed with catapults, combustible missiles, and bows and arrows. In fighting, these soldiers grouped in close cavalry formations against samurai, who were accustomed to one-on-one combat. Local Japanese forces at Hakata, on northern Ky?sh?, defended against the advantageous mainland force, which, after one day of fighting was destroyed by the onslaught of a sudden typhoon. Kublai realized that nature, not military incompetence, had been the cause of his forces' failure so, in 1281, he launched a second invasion. Seven weeks of fighting took place in northwestern Ky?sh? before another typhoon struck, again destroying the Mongol fleet, which was mostly composed of hastily acquired, flat-bottomed Chinese ships especially vulnerable to powerful typhoons.
Although Shinto priests attributed the two defeats of the Mongols to a "divine wind" or kamikaze, a sign of heaven's special protection of Japan, the invasion left a deep impression on the shogunate leaders. Long-standing fears of the Chinese threat to Japan were reinforced. The victory also convinced the warriors of the value of the shogunate form of government.
The Mongol war had been a drain on the economy, and new taxes had to be levied to maintain defensive preparations for the future. The invasions also caused disaffection among those who expected recompense for their help in defeating the Mongols. There were no lands or other rewards to be given, however, and such disaffection, combined with overextension and the increasing defense costs, led to a decline of the Kamakura bakufu. Additionally, inheritances had divided family properties, and landowners increasingly had to turn to moneylenders for support. Roving bands of r?nin further threatened the stability of the shogunate.
The H?j? reacted to the ensuing chaos by trying to place more power among the various great family clans. To further weaken the Kyoto court, the bakufu decided to allow two contending imperial lines—known as the Southern Court or junior line and the Northern Court or senior line—to alternate on the throne. The method worked for several successions until a member of the Southern Court ascended to the throne as Emperor Go-Daigo. Go-Daigo wanted to overthrow the shogunate, and he openly defied Kamakura by naming his own son his heir. In 1331 the shogunate exiled Go-Daigo, but loyalist forces, including Kusunoki Masashige, rebelled. They were aided by Ashikaga Takauji, a constable who turned against Kamakura when dispatched to put down Go-Daigo's rebellion. At the same time, Nitta Yoshisada, another eastern chieftain, rebelled against the shogunate, which quickly disintegrated, and the H?j? were defeated.
In the swell of victory, Go-Daigo endeavored to restore imperial authority and tenth-century Confucian practices. This period of reform, known as the Kenmu Restoration, aimed at strengthening the position of the Emperor and reasserting the primacy of the court nobles over the warriors. The reality, however, was that the forces who had arisen against Kamakura had been set on defeating the H?j?, not on supporting the Emperor. Ashikaga Takauji finally sided with the Northern Court in a civil war against the Southern Court represented by Go-Daigo. The long War Between the Courts lasted from 1336 to 1392. Early in the conflict, Go-Daigo was driven from Kyoto, and the Northern Court contender was installed by Ashikaga, who established a new line of shoguns.
