'Papa? What religion are we?' = Actually, Kurokichi asks, 'What sect do we belong to?'

M.J.: "Shinto is Shinto but Buddhism- which looks after death rites- has various sects. With certain notable exceptions- like the Nichiren Buddhists- the sects all get on quite happily in a good Japanese 'what's the diff?' fashion. What sect you are is largely a matter of what sect your family has always been, because the most important part of all this is what temple your family is buried near."
