靖国神社 (Yasukuni Shrine) is a Shinto shrine located in Tokyo, Japan. It was established in 1869 to honor the spirits of those who died in service to the Japanese Empire, particularly during the Sino-Japanese War and World War II. The shrine enshrines over 2.5 million souls, including soldiers and civilians who contributed to Japan's military efforts. The shrine is a site of controversy, especially regarding visits by political leaders, which some view as a symbol of militarism. It also includes a museum that presents Japan's wartime history, often sparking debates about historical interpretation and national identity in relation to Japan's wartime actions.
