As nations economically prosper, do future generations undergo a steady shift in values? This thesis seeks to analyze the Post-World War II intergenerational shift in Japanese attitudes toward Japanese women and the LGBT, multiethnic, and indigenous communities. Centered around Ronald Inglehart's "Materialist" and "Post-Materialist" theories, this research seeks to contribute to current literature surrounding the development of contemporary Japanese values. Inglehart's "Materialist" theory consists of the idea that individuals pursued various goals in hierarchical order with their base necessities such as sustenance and safety gaining priority. After their base necessities are satisfied, Inglehart believed that people's values shifted, emphasizing belonging, self-expression, and quality of life, all considered "Post-Materialist" values. This thesis utilizes empirical data and qualitative materials to analyze the shift in Japanese views surrounding gender, sexual, and ethnic minorities. This thesis found that Inglehart’s Post-Materialist value change and intergenerational shift were present in views toward women and the LGBT community while views toward the Hafu and Ainu may be backsliding.
