Recently, the prime minister Shinzo Abe visited Yasukuni shrine. Lots of media criticized his visit. For example, Washington Post criticized that the prime minister visited the "war shrine". However, it's not true at all.
Actually, the name Yasu-kuni stands for "make the country peace." People visit Yasukuni shrine in order to pray for peace! Not for war!
Indeed, people labeled as war criminals are also laid to rest there. However, Japanese people don't regard them as heroes just as Korean and Chinese government say. We pray in order to cleanse their spirit not to repeat the war again. The worse the spirits are, the more we should pray for them. This thought sounds strange for you, but it's a style of Shinto. See "Harae" article in Wikipedia for more information.
As praying not to repeat the war again is a good thing, vast majority of Japanese people don't criticize the prime minister's visit to Yasukuni. Left wings only do!
The concept of Harae is not familiar to those who live in other countries, left wings use it for political purposes and intend to misinform the people so that they criticize Japan. Japanese left wings are strongly connected to Korea and China, they act in order to benefit those countries. Their intention is to attack Japan. For me, they seem to increse tention amongst Japan and its neibours. They must desire war.
The article seems really strange for me, a bog-standard Japanese, because we do not call the Japan army as the imperial army. The latter term is popular amongst China and Korea. Japanese people know that the emperor was not a central character of the war, but the Japan army made use of the emperor. So, people other than left wings don't use such a term.
Please do not deceived by such negative propaganda. Japanese people really want peace of the world.
