大和時代
Baekje also exported culture to Baekje's allies in the Wa kingdom of Yamato period Japan. The evidence of friendly relationship of Baekje with Japan is the Seven-Branched Sword which Geunchogo gave to the Yamato ruler. Geunchogo also sent scholars Wang In and Ajiki to Japan to spread knowledge of Baekje culture, Confucianism, and Chinese characters. Then Wani taught Confucian classics to emperor's heir Ujinowakiiratuko.
