Studies have shown that the class-origin earnings gap is observed even among workers with the same level of education and class or occupational position in Europe and the United States, particularly when upper-class workers are analyzed. This study advances the literature by examining whether higher class origin is associated with higher earnings in Japan, outside of the Western context, and how the magnitude of the class-origin earnings gap differs by class destination. Using multiple nationally representative survey data in Japan, this study shows that higher professional and managerial class origin is significantly associated with higher earnings even after controlling for educational attainment, class or occupational destination, and workrelated characteristics. Moreover, a significant class-origin earnings gap is observed not only for higher professional/managerial workers but also for lower professional/managerial and routine nonmanual workers. The earnings gap is not evident for manual workers, suggesting that the resources accumulated through higher class origin may lead to earnings advantages in whitecollar positions but not blue-collar positions. Overall, the results suggest that the class-origin earnings gap is more widespread than previously thought, both outside the elite labor market and in the Western context.
