“I ask the girls to sit naked in front of the mirror at home so they can be comfortable with their own sensuality, to feel every part of their body is beautiful.

Foreign women have a mirror in their bedroom and bathroom and look at their bodies. In Japan, they don’t look at themselves. There’s no privacy.

They dress and undress in confined spaces with no mirror. I tell them: ‘Put some music on and seduce yourself in the mirror.’”
