U.S. President Barack Obama (L) is escorted by Japan's Emperor Akihito (C) and Empress Michiko as an Imperial guard stands guard at the Imperial Palace for the welcoming ceremony in Tokyo, April 24, 2014. Obama will use a state visit to Japan on Thursday to try to reassure Asian allies of his commitment to ramping up U.S. engagement in the region, despite Chinese complaints that his real aim is to contain Beijing's rise.
