Why Japan and Russia have failed to solve the territorial dispute: the 1956 Joint Declaration and the mechanism of political coherence

Despite the several chances of agreement, Japan and Russia have failed to solve the dispute over the Northern Territories/South Kuril Islands. The 1956 model seems to be the most plausible method, but the lack of political coherence of the central politics and the will of negotiation became the factors that hinder the two countries from reaching an agreement. By reviewing the conflicting footprints and strategies of the two countries, the authors argue that the more democratized and diffused a political system is, the more difficult it is to come to an agreement in negotiations. This intensifies the existing theory of foreign policy decision-making process emphasizing the influence of domestic constituents.
