Симодский трактат
Between 1852 and 1855, Admiral Yevfimiy Putyatin of the Russian Navy made several attempts to obtain from the Shogun favourable trade terms for Russia. In June 1853, he brought to Nagasaki Bay a letter from the Foreign Minister Karl Nesselrode and demonstrated to Tanaka Hisashige a steam engine, probably the first ever seen in Japan. His efforts culminated in the signing of the Treaty of Shimoda in February 1855.
