Japan is made up of 98.5% Japanese, 0.5% Korean, 0.4% Chinese and 0.6% other ethnicities. It doesn't seem like the small percentage of non-Japanese cultures has had a big impact on Japanese culture. About 99% of the population speaks Japanese and less than 1% of the population speaks Korean. Japan does not have ethnic, religious and class divisions in its social structure. Even 90% of the population considers themselves middle class. The Japanese have a similar education system to the United States as they implement a 6-3-3-4 system. Japanese people go to elementary school for six years, then high school for three years, then high school for three years, and then about half of high school graduates get a four-year degree. Japan is considered to have one of the best education systems in the world, with a 100% enrollment rate in primary and secondary schools and an illiteracy rate of 0%. Their high school dropout rate is also quite low
