Japanese laws and regulations have been put in place to deal with racism and discrimination, however the government practices what is called “positive discrimination,” while displaying low tolerance for refugees and people from other countries. Japan also makes efforts to prevent the entrance of Muslims, as some Japanese people believe Islam is not compatible with their culture. In 2005, a United Nations special rapporteur on racism warned the Japanese government wasn't doing enough to respond to a growing tide of xenophobia. Three years later, the U.N. released a report that found Okinawans and the indigenous Ainu people of Hokkaido were most affected by racism in Japan, followed by Chinese and Korean migrants.
