In homes, the shrines can be a shelf on the wall, a table or an altar like architectural structure, integrated in the structure of the house or even an entire room, depending on the financial status of the family.
Below is a picture of a typical Japanese “Butsudan”, a portable alter for the home to honor deceased relatives. This is all about traditional Japanese ancestral worship. The Butsudan below is set up for my wife’s late grandfather and grandmother. Every night my mother-in-law makes an offering. This has nothing to do with a belief in the afterlife as my in-laws are not religious folks at all; it’s about bringing memories of the deceased into this world. Mom continues to keep the tradition alive, evidence of the power of culture in driving behavior.
