The Taika Reforms were a series of political and social changes implemented in Japan during the year 645 AD. These reforms aimed to centralize power under the imperial court and reduce the influence of powerful clans. The reforms included land redistribution, the establishment of a tax system, and the creation of a bureaucratic government modeled after the Chinese system. One of the key figures behind the Taika Reforms was Prince Naka no Ōe, who later became known as Emperor Tenji. The reforms marked a significant shift in Japanese governance, laying the foundation for a more organized state and influencing future policies in the Nara and Heian periods.
