Fig. 2-4-1-1 shows the trends in the rate of imprisonment (the rate of imprisoned inmates against imprisonment capacity) over the last 20 years.
As of December 31, 2005, the rate of imprisonment slightly decreased from the same time of the previous year due to an effort to raise the imprisonment capacity. However, the number of inmates has been on an upward trend, and penal institutions are still overcrowded. Among 74 (main) penal institutions, 56 institutions (75.7%) accommodate inmates exceeding their capacity (Source: The Correction Bureau, Ministry of Justice).
