It's the work/life relationship they have in Japan
You forgot the fact that women are in the workforce.
Not only do men have to work 12+ hours a day, and go out for drinks with their boss lest they face being ostracized in the office, but they have to compete with women. These women view the men they work with as at or less than their level because women are hypergamous. You therefore have a significantly larger pool of men viewed as undesirable by women simply by virtue of the women having their own income, and so those men don't get to reproduce. Women in the workforce is a major reason for the decline of the Japanese population, as a further kick to the groin in the already punishing work life of a Japanese salaryman.
This is the future of other female oriented societies where men are being sidelined in favor of women's frivolous wants.
