Japan's problem over the past
As Japan marks the 60th anniversary of its surrender in World War II, its handling of the past still rankles in some parts of Asia.
Unlike the reconciliation in Europe of former foes like Britain and Germany, relations between Japan and her Asian neighbours, particularly China, remain very strained.
Japan's imperial army, which annexed Korea as a colony in 1910, later seized control of large parts of China and South East Asia as the war dragged on.
Its methods were often brutal. Following the 1937 capture of the Chinese city of Nanjing, Japanese troops killed up to 300,000 civilians and raped tens of thousands of Chinese women, historians estimate.
