Spirited Away follows ten year old Chihiro after her parents are turned into pigs and she is trapped in a spirit world centered on a bathhouse run by the witch Yubaba. Scholars James Boyd and Tetsuya Nishimura, writing in the Journal of Religion and Film, argue the film draws on Shrine Shinto and Japanese folk religion more heavily than any of Hayao Miyazaki's earlier work, and that its central image, a bathhouse where a great variety of kami come to be washed clean, embodies a genuinely Shinto insight: that things in the world become polluted through ordinary use and need periodic purification to recover their vitality.
The clearest single scene built on this idea is the arrival of a foul smelling, sludge covered visitor that the staff initially mistake for a low ranking, disgraceful spirit. Chihiro discovers, pulling a bicycle and household refuse out of its body, that it is in fact the kami of a river choked by human dumping, restored to its true, radiant form once the pollution clogging it is physically removed. Miyazaki has said in interviews that he grew up understanding kami as present everywhere, in trees, rivers, insects and wells, an older and more diffuse religious sensibility than the doctrinally organized Shinto of a shrine's official rites, and Boyd and Nishimura read the bathhouse itself as a stand in for this older, folk layer of the tradition, a place where forgotten or disrespected kami still come to be cared for.
The film never names its spirits as Shinto doctrine in so many words. It does not need to; the logic of pollution and purification that organizes nearly every encounter in the bathhouse is, on this scholarly reading, Shinto practice translated directly into image and plot rather than referenced from a distance.
