Japan's Prime Minister Shinzo Abe attends a memorial service ceremony marking the 70th anniversary of Japan's surrender in World War Two at Budokan Hall in Tokyo August 15, 2015. Japanese Emperor Akihito marked the 70th anniversary of the end of World War Two with an expression of "deep remorse" over the conflict on Saturday, a departure from his annual script which could be seen as a subtle rebuke of conservative Prime Minister Abe.
