It was only a few years ago that a girl died in Kumamoto in a similar “exorcism.” Here’s part of an article from 2011:
“Teenage girl dies in Japan ’exorcism' A 13-year-old girl suffocated after she was strapped down and doused with water by her father and a monk who were trying to expel an “evil spirit”, Japanese police said Tuesday. Fifty-six-year-old monk Kazuaki Kinoshita and the girl’s 50-year-old father Atsushi Maishigi were accused of what police described as “waterfall service”: strapping the victim *** to a chair and dousing her face with water.”
