In the 1980s, Japan's economy posted strong economic growth, in stark contrast to the more pedestrian growth other developed economies experienced. In this period, referred to as the "bubble" economy, Japan experienced a sharp increase in the values of land and stocks. The fast paced growth came to a halt in 1991, however, as the Ministry of Finance grew concerned over prospects of a rising rate of inflation, and, accordingly, tightened the nation's money supply. Since then, Japanese economic growth has fallen sharply and the economy has experienced asset deflation, rising levels of unemployment, and falling corporate profits and investments.
