Commodore Perry's expedition played a crucial role in establishing U.S.-Japan relations by using a combination of diplomacy and military presence to compel Japan to open its ports. His arrival with warships made it clear that Japan's isolation would not be tolerated by Western powers, effectively forcing them into negotiations. The treaty that followed laid the groundwork for future diplomatic engagements and economic exchanges between the two nations, significantly altering Japan's trajectory toward modernization.

### Evaluate the long-term impacts of the Treaty of Kanagawa on Japan’s development and its role in global affairs during the late 19th century.

The long-term impacts of the Treaty of Kanagawa were profound, leading Japan from isolation toward rapid modernization and industrialization during the Meiji Restoration. This transformation allowed Japan to emerge as a significant power in Asia and eventually on the world stage. By adopting Western technologies and military practices, Japan shifted from being a secluded nation to actively engaging in imperialism itself, reflecting a complete reversal from its previous stance. This evolution would later play a pivotal role in shaping global dynamics, especially as Japan asserted itself militarily in conflicts such as the Sino-Japanese War and Russo-Japanese War.
