The house that property consultant and ghost investigator Kazutoshi Kodama regularly surveys has a grim history: seven years ago, an elderly woman hanged herself in the bathroom and last year her son died alone, his body undiscovered for roughly 10 days.
Kodama says he has stayed in the house — located in a quiet residential area in Chiba near Tokyo — from 10 p.m. to 6 a.m. nearly 20 times, monitoring with four video cameras, a thermal camera, an electromagnetic field meter, an air pressure gauge, a thermometer and an IC recorder. He takes notes of the readings every hour.
When he is satisfied there are no paranormal phenomena such as unexplained electromagnetic disturbances, he will issue a certificate deeming the property free of ghosts.
