This is about Japan, but like the US, Japan has a restrictive immigration policy and an aging, not-replaced population that's at the core of this issue. Japan has been toying with expanding immigration in the area of health care workers [1] recently, but like in the US, there really isn't a labor shortage issue if immigration policy is liberalized.
So this is like so many other things a complex and mediocre technological solution to what's actually a political issue.
