Yoko's passion for education and understanding the importance of education for women and girls explains her commitment to the development of a school in Tharu Village, a marginalized area of Nepal, where women and girls are victims of poverty and targets for human traffickers. The root cause is lack of education and income earning skills. For the last 20 years, SI of Oita-Midori, where Yoko was a charter member in 1989, has supported this project and to date 16,000 women and girls have gained literacy education and 850 women finished vocational training. In 2014 she received a Commendation of the Tharu Welfare Committee for her work.
