Saori Osu is the epitome of what Japanese Prime Minister Shinzo Abe's "womenomics" policy hopes to cultivate; she combines being the CEO of a consulting firm with being a mother of three.
Her life is a stark contrast to the usual practice of Japanese women, she tells CNBC, because 60 percent quit their job after having their first child.
In many cases, for good reason.
A severe shortage of daycare places has long meant that many women were unable to return to work, and those that did found it impossible to continue due to inflexible company working hours.
As a result, Japan has languished in the bottom third of the World Economic Forum's Global Gender Gap Index, which since 2006 has measured gender equality in the workforce.
In 2014, Goldman Sachs calculated that Japan's gross domestic product (GDP) could be boosted by almost 13 percent if the gender employment gap was closed.
It was one of many warnings on the issue, and they were heeded by Abe, who that year told the WEF, "The female labor force in Japan is the most under-utilized resource. Japan must become a place where women shine."
