I have to say I find your "conspiracy theory" over Japan and North Korea rather bizzare. Japan may not have cracked down on North Korean gangs until recent decades, but then again the same applied to Japanese gangs as well. The lack of action against organised crime was not political. Also, unlike China, Japan only recognises the South Korean government out of the two.
Hello FuManChu,
The Japanese government was aware that its citizens were abducted in 1970s. Yet the government increased trade with N. Korea, becoming N. Korea's largest trading partner in 1980s-1990s. The Japanese government also looked the other way while Korean syndicates routed hard currency to N. Korea.
For what reason do you think the Japanese government took such a passive stance on its citizens being kidnapped, while supplying Dear Leader with hard currency and luxery goods? Information about these kidnapped Japanese citizens were floating around intelligence community, as well as photographs and information. Yet the Japanese government stayed mum as the victim's families cried and protested.
Then, as N. Korea release the nuclear genie, suddenly we see Shinzo Abe meeting with abductee family members on national TV, comforting them after being ignored for 20+ years? And the issue of abudctions being utilized as the moral justification to cut ties with N. Korea and take a hard-line stance?
Is it a conspiracy? No, I think it's Machiavellian Realpolitk at the expense of your own citizens. Japan did not want to see a strong and unfiied Korea, becoming a powerful competitor to Japan. Keeping Korea divided was on their mind, but it kind of backfired.

As for the territorial claim issue, again Japan has kept a passive stance for quite some time. In the past they even prohibited nationalist groups from going to Daoyutai. Then suddenly the government took over and installed a military listening station. Hmm.
On the Korean front, we see that Japan being content with peaceful discussions with S. Korea for 2 decades. Then suddenly we see the government claiming Dokdo/Takeshima as part of Shimae Prefecture since 1905, and send maritime survey ships to violate Korean territorial waters multiple times in 2006.
When asked why they didn't notify the S. Korean government (via prior agreement), the Japanese government responded that since it's actually Japanese territorial waters (EEZ), there was no need to notify S. Korean government. Japan draws its EEZ from Dokdo/Takeshima in conflict with S. Korea's claim.
From the many incidents that has occured, I have to conclude that Japan is starting to take a more hard-line stance on its own territorial claims. This has made Korea and Russia take notice, and we've seen a huge increase of Russian air force intrusions along Japanese airspace in 2006. The Russians are putting Japan on notice that, despite the fall of Soviet Union, "we're still here", and "don't even think about it".
==============
Now, let's examine the conflicting territorial claims.
Both Korea and Russia are in physical posession of land territory claimed by Japan. This means they only need to defend their claims, and the claims include actual, physical islands and not some imaginary line in the ocean.
China's conflicting claims with Japan is more with placement of the imaginary EEZ line than Daoyutai/Senkaaku islets. The current gas field dispute, for example, is a conflict between Japan's claim based on few reefs (far away from Daoyutai) vs. PRC's claim based on continenal shelf.
In ocean EEZ dispute, survey ships are less worrysome than artificial structures, because ships do go home, while artificial structures like drilling stations stay. The PRC placed its drilling stations not only within China's EEZ, but also beyond Japan's EEZ claim:
So, in essence, Japan can only protest about China sucking up an "unfair amount" of natural gas, but not actual, physical violation of Japan's EEZ line. Other than that, the 2 countries can prolly bicker over fishery rights in conflicted area, but not much else.
For this reason, I believe the territorial dispute between S. Korea and Japan will be more serious that PRC-Japan. Your opinion may differ.
