What is happening in Japan in 750CE
The Japanese are rapidly becoming one of the most highly civilized nations in the world at this time, borrowing many elements from Chinese culture: script, artistic and architectural styles, and the Confucian education system. Buddhism is also making great headway. The imperial court of Japan is modelled directly on that of Tang China, and the Japanese government has started sending emissaries to the Tang emperor.
The Taika reforms (646) aimed at creating a Chinese-type state. A Confucian bureaucracy was established, along Chinese lines, and a centralized revenue-collection system set up. All land was claimed to belong to the emperor; large estates were abolished and some land redistributed to peasants.
In 710 a new capital, Nara, was built, modelled on the Tang capital of Chang-an, and this period in Japanese history is known as the Nara period.
