It is through the Kōshin rite of folk religion that the most significant examples are presented. The Kōshin belief or practice is a Japanese folk religion with Chinese Taoism origins and ancient Shinto influence. It was founded by Tendai Buddhist monks in the late 10th century. A considerable number of stone monuments can be found all over the eastern part of Japan around Tokyo. During the later part of the Muromachi period, it was customary to display stone pillars depicting the three monkeys during the observance of Kōshin.
