Japan has tons of problems. Im very well aware of that. Its basically a conservative one party state and lets not even talk about work culture. With that said I dont think we will see people be more critical of Japan as long as it stays "mostly" peaceful/non interventionist and as long as the Nation stays stable. (There might very well be instability in Japans future) Simply put as long as Japan doesnt cause problems for other people outside their borders most people wont care how fucked up Japan really is.
