This is a ceramic bell called 土鈴 "dorei". 鈴 is "Suzu" which means bell and 土 is "do" which means earth, soil and is part of 粘土 meaning clay. So...this is a clay/ceramic bell. These bells have a ceramic ball inside so the sound is a coarse, rolling sound.
Bells of all kinds, have a long history in Japan. Dorei (ceramic bells) date back to the prehistoric Jomon Era (10,000 B.C.-300 B.C.). These bells were used to scare away evil. At Shinto shrines, large bells drape over entrances, as it is said that ringing them calls gets the attention of the Gods allowing one to acquire positive power and authority, while repelling evil.
This is a "migawari suzu" which is a type of "omamori". Omamori are amulets - they are physical objects that contain the spiritual essence and powers of a deity or buddha . " Migawari omamori" (身代わりお守り,means that the item takes the place of the person...so the bad luck is transferred, in this case, to the bell.

This bell is from Bullring - plaza de toros in Ehime, Uwajima. There is oral communication that the fishermen of Fukuura rescued the Netherlands ship which was drifting about Uwakai about the origin of bullfighting in the second half of the 17th century, and two cows presented as the greeting started by having fought by chance, the angle of a cow is automatically compared in a field from a farmer building the strong Japanese beef for farming at the Kamakura period, and there is also an opinion of having made this into amusement.
If bullfighting carries out from it being the spontaneous thing to depend on the combative instinct of a cow, you should think that the origin started with introduction of the cow for farming.
