The People of Japan
The Japanese people make up the overwhelming majority of the population. They are ethnically closer to the other people of eastern Asia. A social class system does persist, it does not have the ethnic basis that can exist in multiracial societies, since the Japanese regard themselves as belonging to a single ethnic group. The few exceptions include those classified as resident aliens, as well as Japanese citizens. Japan also has a small population of Chinese descent.
Culture of Japan
Japan is globally known as a nation that combines both tradition and modernity. For thousands of years, an isolated island country allowed Japan to undergo various cultural evolution, making a unique traditional culture. When connections grew overtime with other countries, Japanese tradition was influenced and altered to create the unique culture of modern Japan. Japan is also evident in its combination of traditional concepts with the latest technology and art that astound the rest of the world.
