Thats par for the course on this topic. Constant exaggerations and hyperbole combined with the ignorance of commenting on a subject out of his range of expertise.
An anecdote I’ve brought up before is my wife’s small hometown in central Japan, at the city hall, most of the information pamphlets are now available in Japanese, Portuguese, Chinese & English (in approximate order of availability). Oddly far more than are available at the Shinjuku city hall.
This really isnt such a bad place to be an immigrant at all.
