I think everyone is familiar with the political positions of Japan and Germany during World War II, but 65 years later, much has changed and much remains the same. Germans for the most part (excluding Neo Nazis) don't condone the actions of the Nazi regime. Even during WWII, Hitler's initial popularity among the Germans was only due to the fact that he hid the Jewish atrocities from the public. However, as the war wore on and people saw how insane Hitler was, they lost a lot of faith in him, even his own soldiers sometimes despised their fuhrer. Needless to say, Germany is now completely the opposite of how it was back then and has clearly put the issue of WWII behind them. This has allowed the international community in which it resides to get along with Germany without conflict over this issue.
Japan's situation, however, is very different. Even though the global community regards its actions in WWII as atrocious, Japan maintains to itself that it's actions were just. Even though Japanese people today don't have the mindset of their WWII counterparts, they have never really repented their role in the second World War. The notion of that war remains a foggy idea in the minds of young Japanese today who were not there to experience it. The subject is rarely mentioned in Japanese history textbooks, and when it is, Japan is always referred to as the liberator of Asia. When we compare Germany to Japan, Germany doesn't make any effort to hide the fact that Nazis massacred millions of Jews. Movies like
Stalingrad were even made by Germans, showing how well they've dealt with the issue. That is why everyone today is familiar with concentration camps and ghettos, but not everyone knows that hundreds of thousands of Chinese and Koreans were used by the Japanese for live medical experiments (dissecting their bodies, injecting them with viruses, Frankenstein-like things) or that many many more were simply buried alive by the Japanese. And to add insult to injury, Japan sometimes even commemorates these war criminals as martyrs of Japan.
The Yasukuni Shrine and the Yushukan Shrine immortalize the
Kami or spirit of many Japanese casualties of war over the years, including many WWII war criminals. The Yushukan Shrine honors the Kamikaze pilots of WWII as heroes and depicts Japan's role in the war as a defender of Asia that was provoked by the Allied powers into violence. Many high-ranking Japanese politicians make special visits to these shrines to honor the dead. Although it can be said that Japanese people place "respect for the dead" very highly, and that they are also honoring Japanese casualties of war other than those of WWII, each and every visit to these shrines sparks resentment in the international community. However, as a result of this, some Japanese Prime Ministers choose to boycott visits to these shrines. In 1978, Hirohito, also known as Emperor Showa, initiated a boycott of the Yasukuni Shrine due to the fact that 14 WWII Class-A war criminals had been enshrined there. The current PM, PM Naoto Kan, also refused the visit the shrine in an effort to speak out to the Asian community that Japan is ready to move on. I think this is a great leap forward for all the countries of Asia because in the past, China and Korea
really really didn't like Japan. And this dislike affected their economic and political relations with Japan. By moving forward and adopting a more "modern" point-of-view, Japan only risks making new allies.
