When stay-at-home mom Mika Sato found herself in Nepal meeting girls rescued from the country's sex trade, she couldn't escape seeing her young daughter's face in theirs, and she knew she had to do something to help.

Just months later, Sato opened a cafe in Okazaki, Aichi Prefecture, in order to raise money for the girls and women who had been sold into a life of sexual slavery.

Badi Cafe, named after the women from the Badi ethnic group, opened in June. It sells coffee beans packaged by the women from western Nepal who have been rescued. She also imports jewelry made by members of the socially "untouchable" caste.
