Intercultural Development Continuum

This week’s lesson on the Intercultural Development Continuum (IDC) helped me better understand how people develop intercultural awareness and learn to appreciate cultural differences. The IDC explains how people move from seeing the world mainly through their own cultural perspective to understanding and adapting to different cultures. The stages include Denial, Polarization, Minimization, Acceptance, and Adaptation.

As a Thai student currently visiting Japan, I have experienced many cultural differences that helped me connect the theory to real life. One of the biggest differences is cleanliness. In Japan, there are very few public trash cans, yet the streets remain extremely clean because people are expected to take responsibility for their own waste. Public transportation is also much quieter than in Thailand, and trains are known for their punctuality. These differences surprised me when I first arrived.

One experience that stood out to me was using public restrooms. In Thailand, many public bathrooms use strong fragrances or air fresheners, so I associate a scented bathroom with cleanliness. In Japan, public restrooms are often spotless and well-maintained, but many rely less on artificial fragrances and more on natural ventilation. At first, I found this uncomfortable because the bathrooms did not always “smell clean” to me, even though they were visually cleaner than many bathrooms I had used before. I realized that my idea of cleanliness was influenced by my own cultural experiences. Although I still prefer lightly scented bathrooms, I am gradually getting used to the Japanese approach. This experience reminded me of the IDC because it showed how easy it is to judge another culture using our own standards before trying to understand it.

At the same time, I also found many similarities between Thailand and Japan. Both cultures value politeness, respect for elders, and maintaining harmony in society. Customer service is highly valued in both countries, although Japan’s concept of omotenashi emphasizes anticipating customers’ needs to an even greater extent.

One example discussed in class was Japanese high school baseball. At first, the players’ emotional reactions after losing a game seemed unusual to me. However, after learning more about Japanese culture, I understood that these actions reflect values such as dedication, teamwork, discipline, and respect for effort. Through the IDC, I learned that understanding another culture requires looking beyond first impressions and appreciating the values behind different behaviors.

Overall, I think this lesson helped me move from minimization toward acceptance. Instead of assuming that cultures are mostly the same or judging differences immediately, I have learned to appreciate both the similarities and differences between Thailand and Japan. The IDC taught me that intercultural competence is not about deciding which culture is better, but about becoming more open-minded and understanding different perspectives.
