The kuge () 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 daimy?, 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. Though there is no longer an official status, members of the kuge families remain influential in Japanese society, government, and industry.
Kuge (from Middle Chinese kuwng-kæ , "royal family") originally described the Emperor and his court. The meaning of the word changed over time to designate bureaucrats at the court. During the Heian period, the relative peace and stability provided freedom for the noble class to pursue cultural interests, and the kuge became leaders and benefactors of arts and culture in Japan. Most of the Kuge resided in the capital city of Kyoto.
Later, in the Kamakura period (1185-1333), kuge became an antonym to buke (warriors' house), that is, samurai who swore loyalty to the shogunate. At this point, kuge began to be used to describe those who worked in the Court; both aristocratic noblemen and commoners.
Two classes formed the kuge: the d?j? () noblemen who sat on the floor with the Emperor; and the jige () who were unable to sit with the Emperor. Although kuge included those two classes, mainly this word described the d?j?, the noblemen.
The highest offices at the court were called kugy? and eligibility was limited to members of d?j? kuge. During the Edo period there were about 130 families of d?j? kuge. The most prominent members of the kuge became regents to the emperor (sessh? or kampaku). These daij?-kan offices were restricted to members of the Fujiwara family.
Though they lost most of their political power, they sustained the court culture and maintained a cultural influence. In particular, after the Sengoku period they lost most of their financial basis and were no longer in a position to act as patrons of culture, but they passed on their knowledge as masters of particular fields such as writing waka poetry and playing instruments such as the biwa, and they had disciples among the daimy? and sometimes rich commoners. As masters of a certain field, kuge gave their disciples many licenses certifying that the disciples had learned a certain field and allowed them to perform in public or sometimes to teach others. Disciples were expected to pay their master a fee for each issued license. During the Edo period, this was an important source of income for the kuge.
The kuge were divided into two classes, the higher dojo and the lower jige. In the 12th century conventional differences were established among the d?j?, separating them into groups according to their office at court. These determined the highest office to which they could be appointed. Within the dojo class, the groupings were:
The jige class was associated with but not a part of the dojo:
