Bronze bells were used as ritual implements during festivals in the Yayoi period (ca. 5th/3rd c. BCE–ca. 3rd c. CE). The varieties of scale and ornament represented among the examples that have been discovered suggest an ever more extravagant ritual sphere. The moderate ornament of the central section almost resembles the patchwork design of a priest’s surplice (Skt. kāṣāya). The bands bordering the sides adorned with a twill herringbone pattern of diagonal lines (known as ayasugimon, “plain weave silk and cedar”) seen here are found on many works from the Tōkai region.
