Approaching the 60th anniversary of the opening of the Tokyo Tribunal in 2006, public opinion was divided over Prime Minister Koizumi's visits to Yasukuni Shrine. One reason for opposition to the visit was that Tokyo Tribunal Class A war criminals are enshrined there.

On August 15 1985, then Prime Minister Nakasone Yasuhiro, despite strong domestic and international criticism, carried out an official visit to Yasukuni. The government later acknowledged during parliamentary questioning that it had accepted the verdict of the Tokyo Tribunal through the San Francisco Peace Treaty. As a result, Prime Minister Nakasone refrained from further visits to the shrine from the following year. Though aware of these historical developments, Prime Minister Koizumi Junichiro has persisted in visiting Yasukuni Shrine since his assumption of office in 2001. In 2005, he again visited the shrine in the face of strong criticism in Japan and abroad. Conservative newspapers like the Sankei Shinbun take the view that “visiting the shrine is not a Treaty violation.” This argument, however, is not in the least compelling. [1]
