Use evidence: Why are the majority ethnic groups in Korea and Japan even more dominant than the Han in China
One possible reason why the majority ethnic groups in Korea and Japan are even more dominant than the Han in China is their homogeneity and relatively small population size. Both Korea and Japan have a much smaller percentage of minority ethnic groups compared to China, where ethnic minorities make up around 8% of the total population. This means that the majority ethnic groups in Korea and Japan have a stronger cultural and societal influence, as there are fewer competing voices.
Additionally, both Korea and Japan have a long history of cultural and ethnic homogeneity, which has helped to strengthen the dominance of the majority ethnic groups. In Korea, the Korean people have a shared language, history, and culture that have been largely preserved throughout centuries of invasions and occupations. Similarly, in Japan, the Japanese people have a strong sense of cultural identity and unity, which has been reinforced by centuries of isolation from outside influences.
Furthermore, both Korea and Japan have historically been more closed off to immigration compared to China, which has led to a more homogeneous population. This lack of diversity has allowed the majority ethnic groups in Korea and Japan to maintain their dominance and influence over society, politics, and culture.
Overall, the combination of cultural homogeneity, small population size, and limited immigration has contributed to the strong dominance of the majority ethnic groups in Korea and Japan compared to the Han in China.
