樺太廳
Japan renounced its claims of sovereignty over southern Sakhalin in the Treaty of San Francisco (1952), having already abolished Karafuto Prefecture as a legal entity on June 1, 1949. However, that treaty did not explicitly approve Russian sovereignty over southern Sakhalin. From Japan's official position, Sakhalin's attribution has not yet been determined, and it is marked as No Man's Land on Japanese maps. Nevertheless, Japan currently has a Consulate-General in Sakhalin's capital city.
