An unusual subject, one would think, for manhole designs in Japan is cows and bulls. This first one is from the highlands of the Chugoku Mountains in northern Okayama, Hiruzen-Kogen, which is apparently the main breeding area for Jersey cows. Who would have thought it?
Chibu, the smallest inhabted island in the Oki Islands group in the Japan Sea off the coast of Shimane, is famous for raising cattle, Unusual for Japan you can bump into them standing in the middle of the roads.
Bullfighting or rather Bull Sumo, is popular in several areas of Japan, including Uwajima on Shikoku.
Bull Sumo is also very popular on Dogo, the largest of the aforementioned Oki Islands. Two of the towns have fighting bulls on their manholes.
