Japan faces many structural challenges related to a shrinking and ageing population and workforce. One solution is to use half the population more effectively. It is only a myth, that more women working would lower the already very low Japnaese birthrate. Kathy Matsui calls for changes and says that "there is no such thing as a glass ceiling, it is just a thick layer of men". Recorded live at TEDxTokyo on May 21st 2011, at the Miraikan, Odaiba.
