Taika Reform 大化改新
(重定向自Taika Era Reforms)
The Taika Reforms(大化の改新,Taika no Kaishin) were a set of doctrines established by Emperor Kōtoku (孝徳天皇 Kōtoku-tennō) in the year 645. They were written shortly after the death of Prince Shōtoku, and the defeat of the Soga clan (蘇我氏 Soga no uji), uniting Japan. The reforms also artistically marked the end of the Asuka period and the beginning of the Hakuhō period. Crown Prince Naka no Ōe (who would later reign as Emperor Tenji), Nakatomi no Kamatari, and Emperor Kōtoku jointly embarked on the details of the Reforms. Emperor Kōtoku then took the name "Taika" (大化), or "Great Reform".
