The Tokyo District Court on Monday sentenced a former industry ministry bureaucrat to 10 years in prison for drugging six women with sleeping pills and then raping or groping them in 2022.

Dai Sato, a 34-year-old former bureaucrat at the Ministry of Economy, Trade and Industry, gave six women in Tokyo a beverage mixed with sleeping pills so that they wouldn't be able to resist his advances, and then sexually assaulted them at a hotel or an internet cafe, the ruling said.

He raped two of them but was unsuccessful in his attempts to have intercourse with the other four individuals because they were too drunk to have sex or for other reasons, it said, adding that he instead groped them or ejaculated in the victim’s underwear.
