a proven tool for growth
and innovation

Corporate Japan is in dire need of increased diversity. In July 2020, a mere 6% of Japanese corporate board members were women. The Japanese Government’s Fifth Basic Plan for Gender Equality calls for directors and statutory auditors of companies listed on the First Section of the Tokyo Stock Exchange to be at least 12% women by 2022. Japan’s primary business federation, the Keidanren, has called for 30% female representation among board members and corporate executive officers by 2030.
OnBoard’s mission is to help corporate Japan achieve these diversification goals in an effective and value-generating manner, allowing Japanese industry to benefit from diverse perspectives and experiences. Diversity, in all forms, is a key driver in building corporate value and embracing innovation.
