A ledger containing the posthumous names of the deceased is called a "Kakocho" (past record book). It is mainly used in Jodo Shinshu Buddhism, but is also used in other sects to keep track of ancestors. It is a valuable item, like a family tree, that allows you to learn about ancestors you never met. Size: 4.5 sun (approx. 13.5 cm) Please feel free to ask any questions.
