Answer:
United States
Step-by-step explanation:
The United States expedition led by Commodore Matthew C. Perry was responsible for forcing Japan to give up its policy of seclusion. The Perry expedition took place between 1853 and 1854, in two different trips. The purpose was to end Japan's policy of isolation, which had lasted 220 years, through the use of coercion and "gunboat diplomacy." This was also a cause for the collapse of the Tokugawa shogunate and the Meiji Restoration.
