The Nagasaki Naval Training Center was a naval training institute, between 1855 when it was established by the government of the Tokugawa shogunate, until 1859, when it was transferred to Tsukiji in Edo.

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.
