Pressure from foreign investors has spurred serious moves among Japanese companies to seek out more female board members this year, according to a startup chief that helps firms do just that.

Formerly Japan’s youngest female mayor while in her mid-thirties, Naomi Koshi is now the CEO of OnBoard K.K., which specializes in training potential female board members and connecting them with Japanese corporates.

More companies, especially listed ones, are seeking her help this year because of commitments to foreign investors and peer pressure from others in the same industries, Koshi said.
