I’m not sure if Kumamoto is unusual, but it seems to have at least its share of nuts and kooks.

The Nagoya District Court ordered the religious body and its head in April 2012 to pay approximately 6.1 million yen in compensation to a woman for having the plaintiff pay a massive amount of money to the organization by telling her that she was possessed by the spirit of a miscarried or aborted fetus and fueling her concerns. The ruling pointed out that the practice was antisocial and illegal."
