Well....

*goes on a very long explanation about how originally there existed various afterlife but then the soul society came in and converted/conquered all spiritual realms and re-routed the cycle of reincarnation so that people only show up in the soul society and they have an automatic linguistic adjustor feature that immediately adjusts them to understand the japanese of the soul society upon emerging there and typically most souls don't have memories of their life from the human world anyway and then to explain the low population of soul society some souls get trapped in the dangai on their way over to the soul society so you can die decades early and not show up and the only true way to ensure you get passed on is to be konsou'd by a shinigami but that's pretty rare in recent times since the soul society put the kibosh on shinigami interacting in the human world following a substitute shinigami escapade so now the realms are pretty much closed which is how it is japanese*

But that'd be too long.
