During the Kamakura period in medieval Japan, Zen Buddhism was introduced and gained widespread popularity. Zen Buddhism taught that anyone could reach enlightenment through perfect concentration and understanding of the religion. This influenced Japanese culture, where complete awareness and mindfulness became important values. The arts also flourished, including poetry, literature written by women, swordplay practiced by samurai, and the tea ceremony which was influenced by Chinese culture. China continued to have a strong influence on Japan, introducing Buddhism and impacting Japanese writing, religion, and classical works.
