Following global condemnation of Japanese Prime Minister Shinzo Abe's visit to a controversial war- linked shrine last month, Japan is now dealing with the ongoing fallout from the move, with a senior official having to visit the United States to account for Abe's actions, the Foreign Ministry here said Thursday. The ministry said that Senior Vice Foreign Minister Nobuo Kishi, the younger brother of Abe, will visit Washington for a week on Monday, during which he is expected to meet with senior U.S. officials and experts and convey to them the intentions of Abe's visit to the Yasukuni war shrine last month. Japan's foreign ministry also said Thursday that former Foreign Minister Hirofumi Nakasone and two other lawmakers met with former U.S. deputy secretary of state Richard Armitage on Wednesday near Washington. Nakasone, the head of a group of lawmakers committed to ensuring positive ties with members of the U.S. Congress, hand- delivered a statement from Abe explaining why he chose to visit the controversial shrine on Dec. 26 -- the first anniversary of his administration reclaiming power. Abe's statement, officials here said, tried to explain that the visit was not meant to antagonize Japan's neighbors, but to inform the souls of the war dead enshrined there of his administration's progress after one year, and to pledge a peaceful future for the nation. But while Armitage said he hopes that Japan's relations with its neighbors will move in a positive direction henceforth, Abe's visit has caused both domestic and global consternation and the move has been lambasted by the U.S. who, in an unprecedented gesture towards an ally, said it was "disappointed" that Japan's leader had wittingly moved to take action that would "exacerbate tensions with Japan's neighbors." Yasukuni is widely seen as a symbol of Japan's militaristic past and serves as a living reminder of Japan's brutal colonial rule in many parts of Asia, including parts of South Korea and China, during World War II. About 2.5 million war dead are enshrined at Yasukuni, including 14 Class-A war criminals, convicted by an international tribunal. Visits to the shrine, located in central Tokyo, by Japanese lawmakers, have consistently undermined trust in Japan's so-called "pacifist stance" and are seen as glossing over a militaristic history. Abe's visit marked the first time in seven years a sitting Japanese prime minister has visited the shrine. Former prime minister Junichiro Koizumi paid a visit in August 2006. The administration of U.S. President Barack Obama said it deliberately chose the word "disappointed" in responding to Abe's visit, according to a senior State Department spokesperson. "I think we've made very clear that we were disappointed, that we think this will exacerbate tensions. I think those words are very clear in their meanings," State Department deputy spokeswoman Marie Harf was quoted as saying of the incident. "I think our message is very clear from the words we chose," added Harf.
