China, Korea, and Japan have been historically close for centuries, thus accounting for their numerous common artistic traditions. From pre-Christian times until the 8th and 9th century AD, the great trade routes crossed from the Middle East through Central Asia into China. Hinduism, Buddhism, some knowledge of ancient Greek, and much knowledge of Indian arts entered into China, and thence in time into Korea and Japan. Perhaps before Christ, the Central Asian art of manipulating hand puppets was carried to China. For more than 700 years, until 668, in the kingdom of Koguryo, embracing northern Korea and Manchuria, court music and dances from Central Asia, from Han China, from Manchuria, and from Korea, called chiso and kajiso, were performed. Many of the dances were masked; all were stately as befit serious court art. They were taken to the Japanese court in Nara about the 7th century. Called bugaku in Japan, they have been preserved for 12 centuries and can still be seen performed at the Imperial Palace in Tokyo, though they have long since died out in China and Korea. In Koguryo's neighbouring kingdom of Paekche, a form of Buddhist masked dance play was performed at court, and, in the 7th century, it too was taken to the Japanese court at Nara by a Korean performer, Mimaji, who had learned the dances while staying at the southern Chinese court of Wu-hou. Called kiak in Korea and gigaku in Japan, the Aryan features of some of its masks clearly indicate Indian (or Central Asian) influence. Such complicated genealogies are common in East Asian performing arts.Korean drama has its origins in prehistoric religious rites, while music and dance play an integral role in all traditional theatrical performances. A good example of this classical theatrical form is the masked dance called sandaenori or talchum, a combination of dance, song and narrative punctuated with satire and humor.
