what was adopted directly from china by japan?\no a calendar system\no religious shrines\no a written…

Brief Explanations:

Japan adopted its written - language from China. Chinese characters (kanji) were introduced to Japan and became an important part of the Japanese writing system. The calendar system in Japan has its own development and was not a direct adoption. Religious shrines in Japan have unique Shinto and Buddhist - influenced characteristics that are not a simple direct adoption from China. The feudal system in Japan also had its own distinct features and development, not a direct copy of China's feudal system.

Answer:

a written language
