Good luck with that. You guys forgot that Japan received South Sakhalin and Kuril island as a result of war which you won (1905). But we returned these lands as a result of war which was won by us back in 1945..Do you want the islands back? Then be ready to war. I think you guys need to ask yourselves if you really need these lands, and what is better for your country, have good relationships with nearest-neighbor or continue dreaming about lands which you will never get.
