You have written that Koreans have never owned dokdo .
and the Japanese have kept dokdo as Japanese territory.
However, when I took a look at SCAPIN 677, the Japanese territory did not include that Liancourt Rocks, which is dokdo.
What the Japanese are currently saying is that the Treaty of San Francisco does not include dokdo as Korean territory. However, in the Treaty of San Francisco, there were no names of Korean Islands that were even bigger than dokdo, which makes the Japanese people's claim weird.
if the Islands that were bigger than dokdo were not in the treaty, why are those islands not Japanese territory? You can obviously see that the Treaty of San Francisco includes islands which are not mentioned directly on the treaty.
