新井白石
These stories have long been questioned by scholars. Ten volumes are too much for the "Analects", and more importantly, his alleged arrival predates the composition of the "Thousand Character Classic" (the early 6th century). Arai Hakuseki (1657–1725) considered that Wani had brought a certain book of Elementary Learning which the "Kojiki" had confused with the "Thousand Character Classic". Motoori Norinaga (1730–1801) claimed that it was pointless to care about details because the "Thousand Character Classic" was mentioned just as a typical book of Elementary Learning. Some assume a different version of the "Thousand Character Classic" was brought but this theory has no clear basis. In short, it is not unnatural for people like Wani to have come to Japan around that time, but there is no strong evidence determining whether Wani really existed.
