> With the exception of WW2
Except for the one time Japan teamed up with Hitler and tried to rape and pillage the world, and not giving up until someone invented and then used nuclear weapons to make them stop. That is a pretty huge asterisk on Japan's claim to being a peaceful nation. I think Japan's neighbors might have a list of other incidents they could bring to mind: https://en.wikipedia.org/wiki/List_of_wars_involving_Japan

It has nothing to do with marriage or definitions. Here's the abstract:
This paper examines the effects of female chief executive officers (CEOs) on firm performance. Using data on nonfinancial listed firms in Japan, we show that only 0.8% of some 42,000 firm-year observations have female CEOs. There is also little evidence that firms appoint more females as CEOs during our sample period. While the stock market reacts positively to the introduction of a firm's first female CEO, the relationship between CEO gender and firm accounting performance is generally not strong. However, when we classify the type of female CEO, the estimated coefficient for a founder female CEO and Tobin's Q is positive and significant.
