Wani (Japanese: Wani, Wani Kishi (王仁, 和邇吉師)) is a semi-legendary scholar who is said to have been sent to Japan by Baekje of southwestern Korea during the reign of Emperor Ōjin. He used to be associated with the introduction of the Chinese writing system to Japan.
Wani is mentioned only in Japanese history books; he is not recorded in Chinese or Korean sources. The main sources of Wani's biography are the Nihon Shoki (720) and the Kojiki (712).
In the 15th year [of the Emperor Ōjin's reign](404 A.D.), in autumn, in August, new moon of rén-xū, dīng-mǎo (the sixth), the King of Baekje dispatched Achiki and offered up two good horses as a tribute [to Japan, along with him]. Then, they were reared in the stable (umaya) atop the hill (saka) of Karu. And, Achiki was entrusted to raise them. Therefore, the place where the horses were raised was called Umayasaka. Achiki also read the Confucian classics well. Then, Prince Uji-no-Waki-Iratsuko took him as his teacher. Now, the Emperor inquired to Achiki, saying, "Is there any scholar superior to you?" He replied, "There is a man called Wani. He is excellent." Then, the Emperor dispatched Aratawake and Kamunagiwake (a male oracle), who were ancestors of the Kamitsuke-no-Kimi clan, to Baekje, to summon Wani. This Achiki is the progenitor of the Achiki-no-Fubito clan. In the 16th year, in spring, in February, Wani had come. Then, Prince Uji-no-Waki-Iratsuko took him as his teacher, learned various classics under him and there was nothing he didn't become thoroughly acquainted with. This so-called Wani was the progenitor of the Fumi-no-Obito clan.
And, [the Emperor Ōjin] ordered [Geunchogo, the King of] Baekje, "If there is any wise man, offer him up as tribute." The person whose name, offered by the command, was Wani-Kishi. And, [the King] gave, as tributes, along with him, ten volumes of the Analects and one volume of the Thousand Character Classic. This Wani-Kishi is the progenitor of the Fumi-no-Obito clan.
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.
