Then there is dating apps that essentially made it near impossible for men that fall below the median: https://www.nippon.com/en/japan-data/h01361/

I'm sure economics plays some role here but I personally wouldn't emphasise it.

Dating apps allow women to more easily access men of higher value while higher value men can access a greater number of women.

Japan has an average IQ of 106, I'm sure a fair portion of that 40% isn't exactly 'low quality' in terms of genetics.

Dating apps are also mostly about photos.

		Yea but those men with 106 IQ on average lose out to men with 120 IQ and good looking on dating apps, right? And the vast majority of those 106 IQ men can't move somewhere else where their IQ advantage comes into play. Passport bros are a thing but they're a very small (but growing) part of the male population.
