 With the territorial and cultural expansion of the Han dynasty into what is today known as the Korean peninsula, the stage was set for the introduction of Confucian texts and teachings into Japan by way of the Korean kingdom of Paekche in the mid-6th century, along with Buddhism and the essentials of Chinese civilization. It must be noted that an ancient Japanese text, Records of Ancient Matters (Kojiki, 712), relates that earlier, Keun Ch’ogo, the ruler of the kingdom of Paekche, had sent an instructor named Wani, along with a copy of the Analects and another Chinese text, the Thousand Character Classic (Qianziwen; Japanese: Senjimon), to the ruler of Yamato around 400 C.E. Presumably the intent was that of educating the Yamato prince in Confucianism and the Chinese language. Controversy surrounds this account, however, making acceptance of it problematic. Still, if nothing more, Wani was a figure of considerable legendary and cultural significance who, according to traditional accounts, was the first scholar-teacher of the Analects to enter the Japanese islands.
