 From 1947 to 1954, the Japanese government's claim shifted from "prior occupation of a terra nullius" to "effective occupation" by "executing state intention to acquire territory".Not later than 1962, Japan again shifted its claim to ""[the 1905] reconfirmation of title to an inherent/ancient territory"", all based on Japan's changing interpretation of the same Cabinet decision document, all the while carefully avoiding its previous claim of incorporation on grounds of "prior occupation of a terra nullius".Korea also claims that Japan's 1905 claim to terra nullius conflicts with its previous recognition (i.e., the 1877 Daijō-kan order) of the islets as Korean territory.
