How has Japan's culture developed when we consider both diffusion and ethnocentrism from its past to the modern day?

Japan's culture has evolved through a complex interplay of diffusion and ethnocentrism. Historically, Japan selectively absorbed influences from China and Korea, adopting Buddhism, Confucianism, and various artistic practices while maintaining a strong sense of national identity. In the modern era, globalization has led to increased cultural exchange, allowing Western influences to permeate Japanese society, yet Japan continues to emphasize its unique traditions, such as tea ceremonies and festivals. This balance between embracing external ideas and preserving distinct cultural practices reflects Japan's ongoing negotiation of identity in a globalized world.
