Answer:
Japan sent its first mission to the West in 1860, when Japanese delegates journeyed to the United States to exchange the ratified Harris Treaty. Although Japan opened its ports to modern trade only reluctantly, once it did, it took advantage of the new access to modern technological developments. From what I remember, according to the terms of the treaty, Japan would protect stranded seamen and open two ports for refueling and provisioning American ships: (Shimmed and Hakodate). As a result, Perry's treaty provided an opening that would allow future American contact and trade with Japan.
