Suzu hanging under the eaves of a Shinto shrine
Suzu (鈴) is a round and hollow Japanese Shinto Bell that contains pellets that sound when agitated. Suzu come in many sizes, ranging from tiny ones on good luck charms (called omamori (お守り)) to large ones at shrine entrances.
Role in Shinto 
At Shinto shrines, large Suzu drape over entrances, as it is said that ringing them calls kami, allowing one to acquire positive power and authority, while repelling evil. Handheld clustered Suzu, similar to jingle bells, are used musically at Shinto ceremonies.
Suzu is also an uncommon female name in Japan meaning "Bell" or "Tin".
