Yes. According to the Tokyo Governor, who kicked up this fuss with his purchase of the islands, the Rape of Nanking never happened, it was a vicious lie spread about by enemies of the Glorious Japanese Empire.
For about a thousand years or so, the islands were considered, by treaty and custom, a Chinese territory. The Japanese took over in one of their bouts of expansionist insanity in the 19th century, I believe, taking advantage of China's "collapse the Kingdom of Heaven every 50 years" policy of continual civil wars.
It's worth noting that entire region is a clusterfuck of competing claims, with Russia and Japan claiming the same islands, China and Japan, South Korea and Japan and....well, you can see a pattern here. And given Japan's compete and utter inability to accept the historical record the rest of the world does, they will never break down and admit these islands were captured as part of a policy of imperialism and conquest.
Japanese revisionism is going to be a major headache in the coming years.
