Korea, China and Japan, three countries in Northeast Asia, form three axes in the world economy with North America and Europe. Since economic reform and openness in china, cultural, economic, and environmental interdependence among them has been increased significantly because of geographical proximity. All three countries are in common in that they have achieved a rapid economic growth since World War II and become the economic powerhouses of the world, but differ considerably in the stages of economic development and real growth rates.This study compares willingness to pay for environmental protection among three countries using the third, fourth and fifth World Value Survey(WVS) data. The estimation results, which used the aggregate data of three countries, show that a rise in income increases the possibility of agreement to an increase in taxes to prevent environmental pollution in general. However, the results using individual country data show that the probability of agreeing to pay environmental protection increases according to the rise in income, but not increase linearly with it. Further, in the case of Japan, there are no differences in the willingness to pay for environmental protection among income groups.We also find that individuals are more likely to pay for an increase in tax for the environmental protection as they prefer greater income gap rather than equal distribution of the income, prefer self-responsibility about living rather than government support, and think that competition is beneficial rather than harmful. This result implies that in Northeast Asian societies, conservatives are more likely to pay for environmental protection than liberals, and this differs from the Western society cases where the liberals are more likely to pay for it. It appears that the decreases in the likelihood of paying environmental protection in year 2000 and 2005 compared to year 1995 are related to the increases in conservatives compared to liberals in the Northeast Asia.
