Answer:
Why did the Japanese close off their ports to the rest of the world prior to Perry’s voyage?
Iemitsu believed that influences from abroad would shift the balance that existed between the Shogun and the feudal lords. Japanese nationals were not permitted to leave the country - even accidentally.
Why did Japan open their ports to trade with the United States?
Because the Tokugawa government did not have the military capability to repulse the Americans, it signed the Perry Convention of 1854, which opened two ports to U.S. ships needing supplies and repairs.
