Four occupationsThe four occupations (), or "four categories of the people" (), was an occupation classification used in ancient China by either Confucian or Legalist scholars as far back as the late Zhou dynasty and is considered a central part of the fengjian social structure (c. 1046–256 BC). These were the shi (gentry scholars), the nong (peasant farmers), the gong (artisans and craftsmen), and the shang (merchants and traders). The four occupations were not always arranged in this order.
KugeThe 公家 was a Japanese aristocratic class that dominated the Japanese Imperial Court in Kyoto. The kuge were important from the establishment of Kyoto as the capital during the Heian period in the late 8th century until the rise of the Kamakura shogunate in the 12th century, at which point it was eclipsed by the bushi. The kuge still provided a weak court around the Emperor until the Meiji Restoration, when they merged with the daimyō, regaining some of their status in the process, and formed the kazoku (peerage), which lasted until shortly after World War II (1947), when the Japanese peerage system was abolished.
Tokugawa clanThe Tokugawa clan (Shinjitai: 徳川氏, Kyūjitai: 德川氏, Tokugawa-shi or Tokugawa-uji) is a Japanese dynasty which produced the Tokugawa shoguns who ruled Japan from 1603 to 1867 during the Edo period. It was formerly a powerful daimyō family. They nominally descended from Emperor Seiwa (850–880) and were a branch of the Minamoto clan (Seiwa Genji) through the Matsudaira clan. The early history of the clan remains a mystery. Minamoto no Yoshishige (1135–1202), grandson of Minamoto no Yoshiie (1041–1108), was the first to take the name of Nitta.
Edo societyEdo society refers to the society of Japan under the rule of the Tokugawa Shogunate during the Edo period from 1603 to 1868. Edo society was a feudal society with strict social stratification, customs, and regulations intended to promote political stability. Japanese people were assigned into a hierarchy of social classes based on the Four Occupations that were hereditary. The Emperor of Japan and the kuge were the official ruling class of Japan but had no power.
Soga clanThe Soga clan was one of the most powerful aristocratic kin groups (uji) of the Asuka period of the early Japanese state—the Yamato polity—and played a major role in the spread of Buddhism. Through the 5th and 7th centuries, the Soga monopolized the kabane or hereditary rank of Great Omi and was the first of many families to dominate the Imperial House of Japan by influencing the order of succession and government policy. The last Soga predates any historical work in Japan, and very little is known about its earliest members.
Minamoto clanwas a noble surname bestowed by the Emperors of Japan upon members of the imperial family who were excluded from the line of succession and demoted into the ranks of the nobility since 814. The Minamoto was the most powerful and most important clan of all four great clans that dominated Japanese politics during the Heian, Kamakura, Muromachi and Edo periods in Japanese history—the other three were the Fujiwara, the Taira, and the Tachibana.
Kofun periodThe Kofun period is an era in the history of Japan from about 300 to 538 AD (the date of the introduction of Buddhism), following the Yayoi period. The Kofun and the subsequent Asuka periods are sometimes collectively called the Yamato period. This period is the earliest era of recorded history in Japan, but studies depend heavily on archaeology since the chronology of historical sources tends to be distorted. The word kofun is Japanese for the type of burial mound dating from this era. It was a period of cultural import.
Sengoku periodThe Sengoku period is the period in Japanese history in which civil wars and social upheavals took place almost continuously in the 15th and 16th centuries. Though the Ōnin War (1467) is generally chosen as the Sengoku period's start date, there are many competing historiographies for its end date, ranging from 1568, the date of Oda Nobunaga's march on Kyoto, to the suppression of the Shimabara Rebellion in 1638, deep into what is traditionally considered the Edo period.
Ryukyuan peopleThe Ryukyuan people (Ruuchuu minzuku or Duuchuu minzuku, Ryūkyū minzoku, also Lewchewan or Loochooan) are a Japonic-speaking East Asian ethnic group native to the Ryukyu Islands, which stretch between the islands of Kyushu and Taiwan. Administratively, they live in either the Okinawa Prefecture or the Kagoshima Prefecture within Japan. They speak one of the Ryukyuan languages, considered to be one of the two branches of the Japonic language family, the other being Japanese and its dialects.
DaimyoDaimyo were powerful Japanese magnates, feudal lords who, from the 10th century to the early Meiji period in the middle 19th century, ruled most of Japan from their vast, hereditary land holdings. They were subordinate to the shogun and nominally to the emperor and the kuge. In the term, dai means 'large', and myō stands for 名田, meaning 'private land'. From the shugo of the Muromachi period through the Sengoku to the daimyo of the Edo period, the rank had a long and varied history.
