Nah man, see I don't agree witchu. I have been to Japan too many times in the last two years to know that they are ramping up their immigration program aggressively to fill the void of workers, as Japan's birth continue to fall precipitously relative to deaths and retirements.

They are now letting in bad characters from all over the world, some of them (such as Turks) are causing a lot of problems. Here's a video of a clash between Turks and Japanese in Tokyo.

I am not trying to be racist against the new immigrants (Turks, Nigerians, etc) because the majority aren't like this, but coming from different cultures with different socioeconomic backgrounds there is bound to be friction. They're not going to adapt overnight to the country like Japan. Their numbers are shooting through the roof, you can't go anywhere in Tokyo anymore without seeing them and the police have grown weaker and more tolerant of those who are participating in bad behavior. They're not able to control criminal suspects anymore.
