Former Tokyo prosecutor Masahito Nishida is accused of engaging in an "inappropriate relationship" with a woman he had interrogated during a 2023 investigation. The alleged affair reportedly involved a "master-servant dynamic" built on psychological manipulation. Nishida allegedly used the woman's expertise in massages to lure her into private meetings and use her emotional vulnerability as an outlet for his desires. He also demanded money for hotel stays and meals, and used her credit card to cover his own expenses. Despite being married with children, Nishida secretly cohabited with a female lawyer and split his time between his two “families” The Supreme Public Prosecutors Office launched a formal inquiry into Nishida in June.
