Event Sponsorship for Leadership and Action for Determined Youth (LADY)

There are very few women leaders in modern day Japan. To solve this problem, four Japanese and American college students established LADY: Leadership and Action for Determined Youth, a leadership program for Japanese high school girls in September 2015. Each member individually realized the importance of women’s issues, but they have come together to work towards one goal, to lead Japanese high school girls to become future women leaders of Japan.


COSMO partners with a number of networks and specialist agencies worldwide to deliver global communication programs that resonate with a Japanese audience.
