They aren't going to increase the Japanese population talking to women like that. One of the reasons why Japan is in the population fix it's in is because women have decided "Screw it, I'm having too much fun being single, and being a married woman is akin to a season in Hell anyway, especially if you are married to a First Son, so I'm going to live with my parents and spend my money on fashion and Host Clubs and Yaoi doujinshi."
The reason why women make the choice to become a "parasite single" is not just a rebellion against society's expectations of being a "good wife and good mother," but it has a lot to do also with the economic situation that pretty much started with the end of the Showa era and the beginning of the Heisei era. When the bubble economy burst in 1990, the earning power of the Japanese male burst as well. The old assumptions collapsed. You didn't graduate a prestigious university and get a job for life. Much of the excesses of Sarariman life was forgiven because, well, he would bring home the salary. Now, after the burst of the bubble economy, employment was scarce and tenuous.
Marriage had long ago evolved from a business arrangement between families to a partnership arrangement between a man and a woman -- love usually was way down the list even during the go-go '70s and '80s -- so the economic viability of the potential husband determined his marriageability. With so many young men graduating from university without the guarantees their fathers and grandfathers have, you wind up with with lots of single men and single women.
There is a huge stigma against birth out of wedlock in Japan, way more than in the West. So the economic and social situation means birth rates have plummeted.
You cannot simply wish away the current situation, or sloganize it away. This is the result of a social collapse unprecedented in Japanese society.
