Did the Pure Land and Zen Buddhism of Japanese traditional culture both originate in China and then spread to Japan?

In fact, Japanese Buddhism has been handed down from China as a whole. A * * * is divided into five categories, with a total of 18 sects, which are called "eighteen sects" in Japanese, among which Zen is one of the five categories, with three sects, namely Cao Dongzong, Linjizong and Huangbizong.

Monk Rong, the founder of Rupai, crossed the sea from Japan to Tiantai Mountain in China to study Zen, and then returned to Japan to establish the school.

For example, the founder Yuan Daoshi crossed the sea from Japan to study Zen in Tiantongshan, China, and then returned to Japan to create.

For example, Yuan Yin, the founder of Huang Bizong, is the Zen Buddhism that Japan crossed the sea to study in Huang Bishan, China, and then returned to Japan to establish Huang Bizong.

However, it should be mentioned that Zen Buddhism in Japan is not quite the same as that in China, because after they went back to establish their own sect, they changed their contents a little to adapt to the Japanese society at that time.

In addition, not only Zen Buddhism, but most Japanese Buddhism changed its content by itself, so it is different from China's Buddhism-for example, they worship the founder of their Sect instead of Buddhism directly.

It seems that the only thing that hasn't changed is Faxiangzong, but because it hasn't changed, it doesn't seem to be grounded, so it doesn't develop well.

By the way, Daozhao, the founder of Faxiangzong, is a disciple of Xuanzang, a famous monk in the Tang Dynasty (that is, Tang Priest in The Journey to the West).
