>>5 Japan has already accepted so many refugees, illegal at that. After the end of World war II, estimated 2 million Korean refugees (war refugees fled from the Korean war and economic refugees before and after the war) smuggled themselves into war-torn Japan under the control of the occupying allied army by whatever ships available.
They committed outrageous crimes: murders, rapes, robberies, unlawful occupation of land pieces, etc saying that they were people of World War II victor nation and must not observe the Japanese law while the Japanese military was dissolved, police force was so weak (police stations were assulted by Koreans) and the allied army let them do it. The amount of land illegally occupied by Koreans is said to be more than half of the total land of Japan on price basis. That is why there are so many Korean villages, towns and city streets on illegally occupied land areas in Japan though Japan has been closed to immigration. Just as British historian Arnold Toynbee called it, invasion without military force. Many Japanese men who came back from overseas battlefields entered Yakuza groups to fight with the Korean.
The welfare recipients ratio of the Koreans is more than ten times that of Japanese among other various racial conflicts. The tremendous suffering inflicted on them by the Korean (now called Zainichi Korean) planted deep rooted rejection against refugees in the Japanese heart.
Emergency state-declared, largest riot of Koreans, Japanese government couldn’t quell it. Allied army was mobilized to put it down.
