Treaty of Kanagawa is not it because it happened during the Tokugawa Shogunate which was before the Meiji Restoration happened. This was when the US signed an official treaty with Japan. Feudalism was established long before the Meiji restoration, way back in the 12th century, and lasted more or less until the end of the Edo period.
