Unfortunately, Japan is a land where most people are choosing not to have babies or sex.
That means it defaults to a land of death culture. A horribly lonely death culture of robot caregivers, full of girly men and spinsters where adult diapers outsell baby diapers. It's just awful.
Therefore it's no surprise that the manliest specimens in Japan can only be found at the zoo.
"Japanese women go ape over manly gorilla."
What if men just started to be men again, and women just started to be women again?
What all the desperately desperate women could just get laid like tile, with real masculine men. What if women could just be happy with a traditional role as mothers and nurturers and men could go back to protecting? What if men and women just went back to getting married and having families?
Dream on, I know.
