Onaibutsu (a Buddhist altar) (御内仏)

Onaibutsu is a Buddhist altar, or a principal image enshrined in it. The term originated from Jodo Shinshu (the Pure True Land school of Buddhism) but is now commonly used by any other schools.

An altar for the family of the chief priest at a temple is called onaibutsu to distinguish it from the altar installed in the main hall. An altar for an individual household is also called onaibutsu.
