WataruTenkawa@SRDas This seems quite reasonable to me, if by "pray" is meant "pray to a higher power." Many people have shrines to their ancestors in their homes, but these are not for praying to a god. Many people go to small neighborhood shrines, where they ask the "gods" in a Shinto sense for help with their business or personal needs. There are not many Christians in Japan, who would be the only ones to pray at home.
