Bronze bell No. 21 from the Kamo-Iwakura site

National treasure. This decorated bronze bell depicts a group of three lively deer. This type of design on the surface of the bell was known as Ryusuimon. This design style features continuous curving parallel lines which resemble water flowing in a stream. It was added later maybe because the original casting was imperfect. It was made from the same mold as Kehi number 4 dotaku in Hyogo Prefecture, Toukiyama dotaku in Osaka Prefecture, and Inomukai dotaku in Fukui Prefecture.
