The Taika Reform was a series of political and social changes in Japan that took place in 645 AD. Initiated by the Soga clan, these reforms aimed to centralize power and strengthen the imperial government. The reforms included the establishment of a new tax system, land redistribution, and the creation of a bureaucratic structure modeled after the Chinese system. One of the key features of the Taika Reform was the adoption of the Ritsuryō system, which outlined laws and regulations for governance. This period marked a significant shift in Japanese society, moving from clan-based governance to a more unified state under the emperor, ultimately laying the groundwork for future developments in Japanese history.
