Well it might not have been in the Japanese governments ideology, but it wasn't the japanese government in China, it was the Japanese army. And the japanese army simply wanted to destroy China and the Chinese people.
The Japanese Army, as powerful as they were, did not have the sheer ideological prestige or even the single-mindedness of their Nazi counterparts.
Even though the massacre of millions of Chinese civilians and POWs was totally unnecessary and skin-crawlingly evil does not mean that the destruction of the Chinese people was a set goal (as opposed to the dismemberment of the Chinese state, which the Japanese had always seen as a threat). It was not the case that people who collaborated with the Japanese were eventually betrayed and themselves systematically killed, as was the fate of Jewish and Ukrainian police in the Reichskommisariats, because that was Hitler's
explicit policy.
@Green Painting: Again, if it wasn't already clear, I don't think the Japanese were nice by any stretch of the imagination. They killed millions of people for no reason other than to feel like they were getting something done, as well as to satisfy their bloodlust, this is true. But whether or not the Japanese were evil is not my point. In fact, whether or not their actions constituted genocide is not my point either. What I am concerned with is the exact intent.
How were the Japanese different from the Nazis, and why? I have already explained this: Killing Chinese people, even millions of them, was not their dead-set ideology. Killing millions of Slav was, however, the
Nazi ideology. There was one way the Russian people west of the Urals could come out of a Nazi victory scenario and that was not one that involved them living as humans, if at all. In Japanese-occupied areas, this was not the case, as I explained in the previous post.
It was possible to work with the Japanese so long as you acknowledged their supremacy as colonial masters. It should be remembered that in addition to the Japanese Imperial Army, there were also Japanese firms and businesses that were to profit from the invasion; it was not just the IJA that was in China, even though, on account of there being a war, the IJA of course took an overwhelming role. In the long run, however, regardless of what some army officers may have thought, business concerns would have wanted to use locals, which would not have been possible if all the locals were dead. While this would be a life of half-subservience at very best, it would still be survival. Again, compare this to German plans to do away with the Slav as the White Man had done with the American Natives, and we get two different pictures.
Recently I read a book by a White Russian from Harbin. I'm not sure exactly how authentic it was since it was published in the USA in 1943, and since I could find only one single reference to it online, but in it the author described the brutality of the Japanese in Manchuria. However, it was by and large IJA-inspired - the killing, raping, plunder, and forced prostitution. On the other hand, the author described the Southern Manchurian Railway (Mantestu) as being staffed by at least a few decent folk, including some Japanese police who actually did their jobs properly, or tried to. This didn't do much good for the local people, especially poor people, but it shows that the Japanese colonial policy, while contradictory in light of the Army's behavior, was not single-mindedly set on extermination.
My view of Japanese brutality is that generally speaking the harder it was for them to govern an area, the more the Army had their way with it. The more of a hand the Army had in an area, the more death and misery there would be. Some of this had to do with resistance, whether actual or perceived; mostly it had to do with the fact that the Army was generally full of crooks. In a Japanese victory scenario, I believe that we would see the Army's position rolled back a bit to make way for colonial administration, as I suspect was the case in Taiwan and Korea. Regarding China in particular, the size of the country was so huge that the Japanese would by necessity have to allow some degree of autonomy to independent warlords or vassals in western and other backwater areas. After all, the main goal of invading China was that of strategic denial: The Japanese were scared to hell by the notion of a strong, unified China. This would allow the IJA to declare victory and reduce its strength.
In practice, this did not happen, and a lot of it had to do with the chaotic nature of the Army that could neither figure out what their specific aims in China were, nor control themselves even when it was possibly in their own interest. I do believe that such horrible atrocities as the Rape of Nanjing reinforced the Chinese will to resist. At the same time, the fact the Japanese
did find many collaborators to use shows that with a few minor changes, a "successful" puppetization of China was possible and not fully incompatible Japanese colonial policies and tradition.
