Imperial Japan refers to the period of Japanese history from 1868 to 1947, marked by the Meiji Restoration, which transformed Japan into a modern industrialized nation. During this time, Japan adopted Western technologies and political systems, leading to rapid economic growth and military expansion. The nation sought to establish itself as a major world power. The era is also characterized by Japan's imperial ambitions, including the annexation of territories such as Korea and parts of China. This expansion led to conflicts, including the Russo-Japanese War and involvement in World War II. The period ended with Japan's defeat in 1945 and subsequent occupation by Allied forces.
