The document discusses the formation of the centralized state in Japan during the Asuka period through influence from China. It notes how Japan adopted Chinese systems of bureaucracy (Ritsuryo codes), religion (Buddhism), culture, and architecture. The Soga clan rose to power by supporting Buddhism and defeating opponents. Prince Shotoku implemented early reforms based on Confucian ideals. Later reforms, like establishing the capital Nara based on Chang'an and the Taika reforms, further integrated Chinese systems of government into Japan. However, these reforms weakened the centralized state over time.
