Nobel Peace Prize laureate Malala Yousafzai has called on world leaders to promote girls' education.
Malala delivered a keynote speech on Saturday at the World Assembly for Women organized by the Japanese government in Tokyo.
Malala said she was attending the conference to speak on behalf of 130 million girls who are still out of school.
She said world leaders must invest in girls' education now in order to create a world where all women and girls can shine.
She later took part in a panel discussion along with UN High Commissioner for Human Rights Michelle Bachelet.
They talked about the lack of women in sectors related to advanced technologies, including artificial intelligence.
Malala was shot by Islamic militants in Pakistan in 2012.
She has continued to campaign for education for girls and women.
She was awarded the Nobel Peace Prize in 2014 at the age of 17.
