TOKYO, April 22 -- Japanese Prime Minister Shinzo Abe on Wednesday tested reactions of victim countries of Japan's past aggression and the international community in Jakarta by omitting offering"heartfelt apology"in his address as analysts said the short essay in Jakarta, along with his upcoming speech in the United States, will prelude the historical revisionist's controversial war anniversary statement that would exacerbate tensions with its neighboring countries. "Japan, with feelings of deep remorse over the past war, made a pledge to remain a nation always adhering to those very principles "of refraining from acts or threats of aggression or the use of force against the territorial integrity or political independence of any country," Abe addressed in the Indonesian capital on the occasion of the Asian African Summit, which also marks the 60th anniversary of the Bandung Conference.

The remarks, in line with Abe's rightist ideology, also went against what the prime minister's predecessor Junichiro Koizumi made 10 years ago during the 50th anniversary of the Bandung Conference at which Japan offers a"heartfelt apology"to the people of Asian nations affected by Japan's"colonial rule and aggression" during and before the war.

The crucial words of"heartfelt apology,""colonial rule"and" aggression"are the corner stone of the world-recognized 1995 Murayama Statement that is welcomed by nations victimized by Japan ' s wartime aggression, but Abe reiterated just before his departure to Indonesia that it is no need to repeat these key words in his planned statement for the 70th anniversary of the end of World War II.

Speaking during a TV program Monday, the hawkish leader said that he would only succeed the"basic way of thinking"in the previous statements issued by prime ministers on war anniversaries and arrogantly added that"now that I've said I'll succeed them,we don't need to write them again,"local reports quoted Abe as saying.

The world's prominent leaders, including German Chancellor Angela Merkel and UN chief Ban Ki-moon, hinted that Japan should seek reconciliation with its neighbors as the 70th anniversary of the end of the past war is widely considered as a golden opportunity for Japan to do so.

Japan's questionable, or even wrong, perceptions over its wartime past are a major obstacle for it to mend ties with neighboring China and South Korea. But sadly, the prime minister is seemingly not going to adhere to the direction that the international community wishes Japan to follow.

When Abe addressed abroad, former Prime Minister Yukio Hatoyama on Wednesday called on Abe to follow the Murayama Statement and to include the key words in his war anniversary statement, adding that he has"considerable anxieties"that Abe's statement may increase tensions among peoples of the Asian region.

The former prime minister said Tomiichi Murayama, the Japanese leader who issued the landmark Murayama Statement, told him in Tokyo on Tuesday that Abe made many remarks on the 1995 statement by saying that he will follow it, he will review it or even that he might possibly change part of it."So Murayama basically said he don't know what Abe is exactly planning to do,"Hatoyama said.

During his speech in Tokyo on Tuesday, Murayama criticized Abe for not recognizing the historical facts of"aggression"and" colonial rule"from his bottom of heart and the reluctance to include these words in his statement, adding that just for the very reason, suspicion was prompted against Japan. "I believe that countries like China, South Korea, and even the United States and other Western countries, understand what is truly in the heart of Abe,"Hatoyama said at the Foreign Correspondents'Club of Japan. "If Abe cut these key words in his statement, it will be taken as a message that he deliberately omitted the words he didn't want to express and it could become a very serious problem indeed." "So, because everyone truly understand what is in Abe's heart about historical issues, he should take extra care to include these words of'aggression,''colonial rule'and'heartfelt apology'in his statement and truly, from bottom of his heart, express and feel sense of apology, sorrow and regret about these issues," Hatoyama said.

He reiterated that if the prime minister would not include these words in his statement, he should simply not issue the statement during the 70th anniversary at all.

Despite saying that Japan and he himself feel deep remorse for the past war, Abe's true feelings about the historical issues were expressed on Tuesday in his offering to the notorious Yasukuni Shrine, which honors Japan's 2.5 million war dead including 14 Class-A convicted WWII criminals, in the first day of its spring festival.

The shrine offering was criticized by China and South Korea as both countries' foreign ministries urged the Japanese leader to meet the country's commitment to face up to its wartime wrongdoings.

Abe visited the war criminal-honoring shrine in late 2013 and the unwise move draw strong protests and criticism not only from its neighbors, but also from the United States that expressed disappointment over the shrine visit as it could further worsen regional stability.
