-Korea: Korea has had a long history of influencing Japanese culture; the horse, terrace farming, and the character system used for writing Japanese have all come to Japan via Korea.

-China: they learned of and adopted Buddhism as their chosen religion. The Japanese adapted China’s ideographic writing system for the Japanese language. They also learned to read Chinese and were greatly influenced by classical Chinese texts. Scholars were sent to China to learn its ways of governing and the wisdom embodied in Confucianism. The Japanese monarchy sought to force Buddhism upon the reluctant Japanese people. Yet many ordinary Japanese continued to cling to their native Shinto religion.
