I watched a documentary last year which was pretty interesting, and sad. It's the abundance of "omega" men that seem to be a big part of the problem, though you can't put all the blame on them for the culture shift. Much like in the US and based on the video in the OP's post you can see there are plenty of guys willing to take advantage of this true "no good men left" crisis in Japan.

I lived in Japan over 15 years ago, maybe it's time for me to move back and take advantage of the WGF.
