The Yasukuni Shrine, established in 1869 by Emperor Meiji, is a significant Shinto shrine in Tokyo that commemorates those who have died in service to Japan. It has been a subject of controversy due to the enshrinement of war criminals among the 2.5 million souls honored there. The shrine includes the Chinreisha, built to pacify the souls of all war dead, regardless of nationality, reflecting Japan's complex history and the shrine's role in it.
