Values of deference to authority have long been prevalent in Japan and China. These two societies feature hierarchical social structures, harmonious orientations, and collectivism, which are regarded as cultural characteristics of East Asia. Through distinguishing traditional values in the political sphere from those in the non-political sphere, this article examines the relationship between traditional values and political deference levels in Japan and China. The empirical results show that conformity in family and school, preference for political harmony, and prioritization of national interests positively correlated with political deference in the two countries. However, prioritizing family and collective interests significantly correlated with political deference in China, while no significant effect was observed in Japan. Neither did preference for harmony in community and in the workplace have a positive effect on political deference in Japan.
