A Japanese man is accused of drugging and raping dozens of women while posing as a doctor in a bogus sleep study, authorities said Tuesday.

Hideyuki Noguchi, 54, was taken into custody after videos of the alleged assaults surfaced on porn sites, Tokyo Broadcasting System and other outlets reported.

Police in Chiba, east of Tokyo, said they have confirmed 39 victims, but believe there could have been upwards of 100, according to the AFP.

The alleged assaults occurred over a period of two years beginning in September 2011, prosecutors said.

Police believe Noguchi lured victims to hotels and resorts in Tokyo, Chiba, Osaka, Tochigi and Shizuoka under the guise of conducting “clinical research measuring blood pressure during sleep.” The victims volunteered by responding to Noguchi's online ads, police said.

He allegedly gave the women sedatives, then sexually assaulted them while they were passed out. Cops said Noguchi pedaled videos of the assaults to pornographers, earning the equivalent of about $85,000.

Noguchi is not known to have any medical training or related credentials.
