or extended families, including their dependants. Each clan was headed by a patriarch who performed sacred rites to the clan's kami to ensure the long-term welfare of the clan. Clan members were the aristocracy, and the kingly line that controlled the Yamato court was at its pinnacle. The Kofun period of Japanese culture is also sometimes called the Yamato period by some Western scholars since this local chieftainship arose to become the Imperial dynasty at the end of the Kofun period. Asuka period The is generally defined as from 538 to 710. The arrival of Buddhism marked a change in Japanese society and affected the Yamato government. The Yamato state evolved much during the Asuka period, which is named after the Asuka region, south of modern Nara, the site of numerous temporary imperial capitals established during the period. The Asuka period is known for its significant artistic, social, and political transformations, which had their origins in the late Kofun period. Artistically, the term Tori Style is often used for the Asuka period. This is from the sculptor Kuratsukuri Tori, grandson of Chinese immigrant Shiba Tatto. Tori Style inherits Chinese Northern Wei style. The arts during the Asuka and Nara periods are similar to contemporaneous art in China and Korea. One example of this is Tori Busshi's Shaka triad which reflects the style of early to mid-sixth-century Chinese style. Introduction of Buddhism According to Nihon Shoki, was officially introduced to the Yamato court through Baekje in 552, while it is widely recognized Buddhism was introduced in 538 based on the biography of Prince Shōtoku (Jōgū Shōtoku Hōō Teisetsu) and the record of Gangō-ji (Gangōji Garan Engi). Initial uptake of Buddhism was slow. Nihon Shoki records that when Emperor Kinmei discussed about the acceptance of this new foreign religion, Soga no Iname expressed his support while Mononobe no Okoshi and Nakatomi no Kamako (later the Fujiwara clan) opposed not on religious grounds, but more so as the results of feelings of nationalism and a degree of xenophobia. With the dawn of the Asuka period, the use of elaborate kofun tombs by the imperial family and other elite fell out of use because of prevailing new Buddhist beliefs, which put greater emphasis on the transience of human life. Commoners and the elite in outlying regions, however, continued to use kofun until the late seventh century, and simpler but distinctive tombs continued in use
