A lot of anime seems to skew towards the 'mundane fantastic' side of things, even in contemporary, realistic settings.
I think it has something to do with the native folk religions being a more ingrained part of the cultural background noise? Ghosts and youkai are just accepted as being... not 'real', by most people, probably, but. Just a thing that happens in stories.
I remember an episode of Hidamari Sketch, otherwise a down to earth story about art students, had an episode that possibly involved one of the characters channeling a kitsune. Just because.
