I will try to answer, I'm not sure if it's right
On July 8, 1853, American Commodore Matthew Perry led his four ships into the harbor at Tokyo Bay, seeking to re-establish for the first time in over 200 years regular trade and discourse between Japan and the western world. Although he is often credited with opening Japan to the western world, Perry was not the first westerner to visit the islands. Portuguese, Spanish, and Dutch traders engaged in regular trade with Japan in the 16th and 17th centuries. Persistent attempts by the Europeans to convert the Japanese to Catholicism and their tendency to engage in unfair trading practices led Japan to expel most foreigners in 1639. For the two centuries that followed, Japan limited trade access to Dutch and Chinese ships with special charters.
There were several reasons why the United States became interested in revitalizing contact between Japan and the West in the mid-19th century. First, the combination of the opening of Chinese ports to regular trade and the annexation of California, creating an American port on the Pacific, ensured that there would be a steady stream of maritime traffic between North America and Asia. Then, as American traders in the Pacific replaced sailing ships with steam ships, they needed to secure coaling stations, where they could stop to take on provisions and fuel while making the long trip from the United States to China. The combination of its advantageous geographic position and rumors that Japan held vast deposits of coal increased the appeal of establishing commercial and diplomatic contacts with the Japanese. Additionally, the American whaling industry had pushed into the North Pacific by the mid-18th century, and sought safe harbors, assistance in case of shipwrecks, and reliable supply stations. In the years leading up to the Perry mission, a number of American sailors found themselves shipwrecked and stranded on Japanese shores, and tales of their mistreatment at the hands of the unwelcoming Japanese spread through the merchant community and across the United States.
