Taiwanese Hokkien, a topolect among the many varieties of Chinese, is spoken by around 70% of the population of Taiwan. The main languages spoken in Taiwanese are dialects of Chinese, a situation which resulted from cultural imperialism of China on Taiwan. Japanese was also introduced to Taiwan during the Japan occupation of Taiwan. Some indigenous languages have managed to survive throughout the history and are spoken by a small minority, mainly the older generation.
