Chris and those he collabs with like Connor and Ryotaro give a good insight into Japan without the weeb coloured glasses.

The 'problem' Japan has is that it has a lot of niche businesses that cater to one certain audience that become consistent customers. An example of this is their bar scene as you have themed bars from nuns, muscle girls, shooting range etc and all this variety makes it a content goldmine for streamers.

The issue comes in that these streamers getting great numbers attracts the bottom feeders like this guy who only knows being an asshole for views and thinks doing is skit in Japan will get him more viewers.
