The highest tolerance level for all countries were for living next to someone of a difference race. Belgians and Fins are the most racist here (17%), while Japan comes only 4th with just 11% (but why do most landowners make so much fuss about renting their accommodation to a foreigner, even to Japan-born Koreans ?). I guess the people who surveyed the Japanese must have been non-Japanese, and many people didn't answer frankly on this one.
Not all Japanese are landlords.
