Imperial Shrine of Yasukuni informally known as the Yasukuni Shrine (靖国神社) is a Japanese Shinto shrine. The remains of 2,466,532 bodies are interred there, many of whom died during World War II. Among those are 1,068 convicted war criminals, 14 of whom were A-Class war criminals. (Among the 14 are Hideki Tojo, called Japanese Adolf Hitler)
South Korea, Taiwan, China, some Southeast Asian countries and some major Japanese politicians are opposed to paying tribute the Yasukuni Shrine. This is because official paying of tribute at the shrine is indicative that Japan has not fully come to terms with its military aggression and war crimes.
