大化改新
The new emperor, together with the Imperial Prince Naka no Ōe, issued a series of reform measures that culminated in the Taika Reform Edicts in 646. At this time, two scholars, Takamuko no Kuromaro and priest Min (who had both accompanied Ono no Imoko in travels to Sui Dynasty China, where they stayed for more than a decade), were assigned to the position of "Kuni no Hakase" (国博士; National doctorate). They were likely to take a major part in compiling these edicts which in essence founded the Japanese imperial system and government.
