It seems that the Japanese have yet to express true sorrow for their wartime wrongs. I don't think that in any Japanese history class, Japan's war crimes are ever mentioned. Japan's relations with China and South Korea became strained further when in 2005, the PM visited Yasukuni Shrine, and a history textbook was released which glossed over Japan's war crimes, including the "Rape of Nanjing".
I think every Japanese citizen MUST visit Nanjing at least once in their lifetime to learn about the horrible actions their military commited against Nanjing's civilians in 1937. You can NEVER try to whitewash history, no matter how shameful it is. At least 300,000 Chinese were raped and murdered during the massacre; some Japanese historians say it was a lot less, others even denied it happened. And let's face it; Nazi Germany murdered over 6 million Jews, the Empire of Japan murdered 10 million Chinese. Germany punished their own war criminals, America punished Japan's. Germany have officially apologised and payed compensation for their atrocities, Japan never has. In the German educational system, all students MUST learn about Nazi war crimes and visit a concentration camp at least once; the Japanese system hardly (if ever) does anything like that. Germany and Israel have good relations with each other, Japan and China (as well as North AND South Korea) don't really. Jews and Israelis generally like Germans today, many Chinese (and Koreans) still hate Japanese people. JAPAN, WAKE THE FUCK UP AND ADMIT YOUR GUILT!!!
Apart from that though, I still love Japan. The people are one of the nicest and friendliest I've ever met, and their exports (technology and food etc.) are awesome. I just wish that the Japanese knew the truth about what happened in Nanjing...
