Answer:
Commodore Perry had a fleet that was technologically superior.
Step-by-step explanation:
Initially, Commander Perry attempted to negotiate with the Japanese by taking a letter from the president, but he had access to Tokyo denied.
Perry returned to Tokyo 7 months later, in charge of a squad technically superior to Tokyo and threatening to use force, initially refused to negotiate with the Japanese officials and demanded to speak with the Japanese emperor. This time, the shogun Tokugawa Ieyoshi was in fact the man of the laws of Japan; for the emperor to interact in some way with foreigners was out of the question. In the end, Perry concluded that it was better to try a treaty with Xogun representatives than with the emperor.
