tend to dominate the editorials of newspapers, while the right tend to dominate magazines. Debates regarding war crimes were confined largely to the editorials of tabloid magazines where calls for the overthrow of "Imperialist America" and revived veneration of the Emperor coexisted with pornography. In 1972, to commemorate the normalisation of relationship with China, Asahi Shimbun, a major liberal newspaper, ran a series on Japanese war crimes in China including the Nanjing massacre. This opened the floodgates to debates which have continued ever since. The 1990s are generally considered to be the period in which such issues become truly mainstream, and incidents such as the Nanking Massacre, Yasukuni Shrine, comfort women, the accuracy of school history textbooks, and the validity of the Tokyo Trials were debated, even on television. As the consensus of Japanese jurists is that Japanese forces did not technically commit violations of international law, many right wing elements in Japan have taken this to mean that war crimes trials were examples of victor's justice. They see those convicted of war crimes as , Shōwa being the name given to the rule of Hirohito. This interpretation is vigorously contested by Japanese peace groups and the political left. In the past, these groups have tended to argue that the trials hold some validity, either under the Geneva Convention (even though Japan hadn't signed it), or under an undefined concept of international law or consensus. Alternatively, they have argued that, although the trials may not have been technically valid, they were still just, somewhat in line with popular opinion in the West and in the rest of Asia. By the early 21st century, the revived interest in Japan's imperial past had brought new interpretations from a group which has been labelled both "new right" and "new left". This group points out that many acts committed by Japanese forces, including the Nanjing Incident, were violations of the Japanese military code. It is suggested that had war crimes tribunals been conducted by the post-war Japanese government, in strict accordance with Japanese military law, many of those who were accused would still have been convicted and executed. Therefore, the moral and legal failures in question were the fault of the Japanese military and the government, for not executing their constitutionally defined duty. The new right/new left also takes the view that the Allies committed no war crimes against Japan, because Japan was not
