Final answer:
Confucianism is the other major religion that was imported from China and became established in Japan alongside Buddhism.
Step-by-step explanation:
Beyond Buddhism, another religion that was imported from China and flourished in Japan is Confucianism. Initially brought to Japan through contact with China and Korea, Confucianism’s influence grew, alongside Buddhism, during the sixth and seventh centuries.
Its integration into Japanese society was part of a greater cultural and religious import from China, which also included Chinese-influenced written language. Japanese elites, particularly from the aristocracy, often practiced Confucian ideals alongside indigenous traditions such as Shintoism, creating a rich tapestry of cultural and religious practices.
