Recruitment kickbacks are illegal in Japan, they're not "society's rules." More likely these are shady web recruiters that dredge up workers that don't comply with Japanese labor and immigration laws and steer said workers to employers desperate for any kind of workers. Given Japan's cratering birth rate, companies will take anyone to fill positions and are willing to pay these kickbacks for no questions asked. Given how frequently aberration like these and so called Black Companies show up in Japanese popular culture, I have to ask, does anyone enforce labor laws in Japan? Or is exploitation somehow been made socially acceptable?
