The Baekje kingdom's style was particularly influential in the initial stages of Asuka sculpture. It was in 552 that King Seong of Baekje sent a gilt bronze image of Sakyumuni to Yamato Japan according to the "Nihon shoki". Most scholars, based on other Japanese records, consider a 538 date to be more accurate. While it is impossible to know what this first Buddha in Japan looked like, an image similar to the Yong'a Buddha, contemporaneous because it is dated to 539, leads some scholars to speculate that King Seong's proselytizing image looked similar to it. Another Japanese source, the "Gangōji Garan Engi", however, identifies the image as the "prince." This suggests that the initial image was the prince Sidhartha in the pensive pose on the verge of enlightenment, an iconography popular in China. Images in the pensive pose are almost always associated with Maitreya in Korea. However, another iconography associated with the prince Sidhartha is the Buddha at birth. Since this source also lists items for a lustration ceremony some scholars believe that the image was of the infant Buddha. Although Buddhism was introduced into Yamato Japan at a relatively early period, it was not until the 7th century that the pro-Buddhist Soga clan succeeded in eliminating its rivals to allow Buddhism enjoy the support of the central polity.
