[Machine Translation] In 1853, the Black Ships arrived in Japan. It was a huge American warship led by Perry. The Shogunate, under pressure from the Imperial Court to open the country, subsequently concluded treaties with the U.S. and other foreign nations, and the struggle between the expulsion of foreigners and the opening of the country to the outside world intensified. The movement to exclude the emperor and expel the barbarians from the country grew, and eventually a battle ensued in an attempt to overthrow the shogunate by force. Many people emerge from the upheaval at the end of the Tokugawa Shogunate to lead the next era.
