The economic history of Japan is most studied for the spectacular social and economic growth in the 1800s after the Meiji Restoration. It became the first non-Western great power, and expanded steadily until its defeat in the Second World War. When Japan recovered from devastation to become the world's second largest economy behind the United States, and from 2010 behind China as well. Scholars have evaluated the nation's unique economic position during the Cold War, with exports going to both U.S.- and Soviet-aligned powers, and have taken keen interest in the situation of the post-Cold War period of the Japanese "lost decades".
