It's literally because non JP viewers are getting tossed out of the live view count at a much higher rate than JP views.
This started happening back in December and can be seen in the live view count graphs.
This is what a graph for EN used to look like before December.

https://holo.poi.cat/stream/VhM4FoxqdZ8As you can see, there are these weird spikes on the graph at a regular interval. To contrast, the JP members don't usually have graphs that look like that unless they're doing something that has a lot of non JP viewers.

Contrast those to Shigure Ui who is the least likely to have a lot of non JP views.
