Sonnō jōi was a yojijukugo phrase used as the rallying cry and slogan of a political movement in Japan in the 1850s and 1860s, during the Bakumatsu period. Based on Neo-Confucianism and Japanese nativism, the movement sought to overthrow the Tokugawa shogunate and restore the power of the Emperor of Japan.

Bakumatsu was the final years of the Edo period when the Tokugawa shogunate ended. Between 1853 and 1867, under foreign diplomatic and military pressure, Japan ended its isolationist foreign policy known as sakoku and changed from a feudal Tokugawa shogunate to the modern empire of the Meiji government. The major ideological-political divide during this period was between the pro-imperial nationalists called ishin shishi and the shogunate forces, which included the elite shinsengumi swordsmen.
