My comment was about the increasingly high bar for entrepreneurs / protectionism. Immigration will happen regardless of the cost of a business visa...

What is a "low quality immigrant" and why do you think immigrants with money are "high quality immigrants? Because the most damage I've seen done to Japan and the culture is rich people from Singapore, China and Taiwan buying up large swathes of property and then keeping them vacant while driving up property prices and locking out locals. The high price of a business visa will ensure this trend accelerates as more and more actual well intentioned foreigners are locked out of opportunities. Basically if you're a hedge fund, you have the ability to setup shell companies and rape the place.

Anyway, there is still mass migration happening, and it will continue to happen as the population ages they need more workers, it's everywhere now, airports, combinis etc, that has nothing to do with the "business visa". Most actual poor people were never planning to come here to start a business anyway, they were coming here to do slightly less shitty jobs than they were doing in their home countries.
