Joyanokane is the bell which rings out the old year.
The bell is typically rung 108 times to cleanse the listener of the 108 mortal desires (bonno) that, in traditional Buddhist thinking, are the cause of suffering.
After 108 ringing, you can receive Omikuji which are random fortunes written on strips of paper.
