Recently I did a smidgen of research into a territorial dispute between Korea and Japan over the Liancourt Rocks/Dokdo/Takeshima for an essay contest sponsored by a Korean newspaper. Of course, I wanted to win the prize money, so in the essay I concluded that the rocks rightfully belong to Korea.

But it's really not so clear-cut. Both sides claim primary source materials (old maps and legal documents) support their respective claims.
Anyway, Japan is also trying to get some of the Kuril Islands back from Russia. And they're in it with China over the Senkaku/Diaoyu Islands. In all 3 cases, Japan is wrangling with interpretations of the Potsdam Declaration and Peace Treaty of San Francisco in order to legitimize their various claims.
Now, none of these disputes is particularly new, but it looks like Japan has been throwing more fuel on each of these fires in the past few years.
To me, this suggests that, at best, Japan feels no genuine remorse for what it did during its imperialist period, and at worst, that maybe this spirit is still alive and kicking, all the way to the top echelons of the gummit. I say this, but I actually like Japan. I have no agenda against them.
So anyway, if you're a historian or history buff and are interested in the region or WWII, how about giving a glance at the official statements from Japan's and Korea's respective Ministry of Foreign Affairs and rendering a verdict?
