When mdid japan end its practice of isolationism?

Japan ended its practice of isolationism in 1853 when Commodore Matthew Perry of the United States arrived in Tokyo Bay, demanding the opening of Japanese ports to American trade. This led to the signing of the Treaty of Kanagawa in 1854, which marked the beginning of Japan's engagement with the outside world. The Meiji Restoration in 1868 further accelerated this process, as Japan sought to modernize and industrialize by adopting Western technologies and practices.
