Japanese right-wing protesters demonstrated in front of the U.S. embassy in Tokyo on Thursday (December 8) a day after the 75th anniversary of the Japanese bombing of Pearl Harbor on December 7th 1941. Protesters drove trucks and vans equipped with loudspeakers past the U.S. embassy demanding an apology for the dropping of atomic bombs on Hiroshima and Nagasaki, and the U.S. bombing of Japanese civilians during World War Two. The U.S. embassy released a security message to citizens living in Tokyo that approximately 30 vehicles would disrupt traffic around the building throughout the day. Japanese Prime Minister Shinzo Abe is set to visit Pearl Harbor in late December with U.S. President Barack Obama to make him the first serving Japanese prime minister to visit the naval base in Hawaii since the end of the U.S. occupation of Japan in 1952. Japan's chief cabinet secretary, Yoshihide Suga said Abe's planned visit to Pearl Harbor is to strengthen the Japan-U.S. alliance. "We'd like to contribute to the peace and prosperity of the Asia-Pacific region and international community by reinforcing the Japan-U.S. alliance which is called an Alliance of Hope," he said. Japanese forces attacked Pearl Harbor with torpedo planes, bombers and fighter planes on the morning of Dec. 7, 1941, bombing the U.S. fleet moored there in the hopes of destroying U.S. power in the Pacific. The attack led to the United States entering World War Two and the eventual defeat of Japan in August 1945, days after U.S. atomic bomb attacks on Hiroshima and Nagasaki killed hundreds of thousands of civilians. U.S. President Barack Obama became the first serving U.S. president to visit Hiroshima earlier this year and offered flowers to the victims of the atomic bombing but no apologies.
