This influx has coincided with a troubling rise in teenagers and women in their early twenties turning to the sex industry to survive, Tanaka said, alongside an alarming increase in violence. "It's getting worse. Much worse," he said, shaking his head. "There are more kids here and more violence, but our organisation cannot do anything more than we are already doing." Tanaka's frustration is palpable as he reflects on his decade-long struggle to support the young Japanese women who wash up in Tokyo's notorious Kabukicho district – a maze of bars, love hotels, and host clubs where the vulnerable are often preyed upon.
