It's phenomena like hikikomori, social shutouts who can't cope with the immense pressure of Japanese societal hierarchy, which has become a far more viable lifestyle (than it already had been) due to advances in technology.
Along with that came the emergence of the "herbivore men" in Japanese society, partly also a reaction to the immense pressure put on Japanese men to be "successful" in an economy that can't supply "successful jobs" to everybody. Japanese men pretty much invented that whole mgtow-thing before it became popular.
The scary angle is a comparison with John Calhoun's Mouse Utopia experiment [2].
