Fig. 5-2-2-1 and Fig. 5-2-2-2 show trends in damage for the 6 types of offenses, homicide, robbery, bodily injury, extortion, rape and indecent assault (hereinafter referred to as "6 types of offenses resulting in death or bodily injury" in this section. Extortion is included because the Criminal Statistics compiled by the National Police Agency include the number of persons injured due to extortion.)

   Fig. 5-2-2-1 shows the trends in the number of victims killed or injured per reported case for the 6 types of offenses resulting in death or bodily injury. There has been no major fluctuation in the trend in the number of victims killed or injured for all of the 6 types of offenses, except for the number for homicides in 1995. As for robbery and rape, which are not committed for the se of killing or injuring a person unlike homicide and bodily injury, the number of victims killed or injured per reported case is large, 0.3 to 0.5 person per case, which indicates that these types of offenses have a violent nature that is likely to result in death or injury.

   Fig. 5-2-2-2 shows the trends in the number of victims slightly injured, those severely injured and those killed, by type of offense, as well as the rates of victims killed/severely injured and those slightly injured per reported case (The rate of victims slightly injured is not charted for bodily injury because victims of this type of offense suffer injury without exception. Victims of extortion only include those slightly or severely injured because they would be reported as victims of bodily injury (resulting in death) if they are killed). The number of victims killed/injured is on an increasing trend along with the recent increase in the number of reported cases for all of the 6 types of offenses except for homicide.
  As for homicide, both the rates of victims killed and those severely injured have been repeatedly increasing and decreasing within a certain range, showing a slight decline in recent years (the outstanding rise in the numbers of victims severely injured and those slightly injured in 1995 was due to a larger number of victims injured by the Sarin gas attack on the Tokyo subway system.)
  As for robbery, the number of reported cases was 6,393 in 2001, up by 23.6% from the previous year. The total number of victims killed/injured was 3,218 (up by 575 from the previous year), of which 80 victims were killed (up by 29.0%), 301 were severely injured (up by 9.1%), and 2,837 were slightly injured (up by 23.1%), which indicates a rapid increase in the number of victims killed or injured due to robbery. Since l974, the rate of victims killed or severely injured has been between 4.5% and 7.0% and the rate of slightly injured has been between 35.8% and 49.0%.
  As for extortion, along with the increase in the number of victims injured, the rates of victims slightly injured and those severely injured have been on a constant rise. The figures indicate the increase of cases in which extortion involves injury to victims since 1996.
  As for bodily injury, the rate of victims killed/severely injured, which had been on a constant rise, started to decrease in 2000 due to the fact that the number of cases involving slight injury increased more significantly than the increase in the number of cases involving death or severe injury.
  As for rape and indecent assault, the rate of victims slightly injured has been on a gradual decline in the long term, showing a repeated trend of increase and decrease. The rate of victims killed has been at almost the same level.
  These figures indicate that the rate of victims slightly injured and the rate of victims killed/severely injured are not corresponding with the increase/decrease trend in the number of reported cases and the number of victims killed/injured in respect of homicide, robbery, rape and indecent assault, without showing significant fluctuations over the last quarter of a century. In the past few years, the number of reported cases increased rapidly for robbery, rape and indecent assault, which is not only due to the rapid increase in the number of reported cases involving slight injury but also the increase in the number of reported cases involving death or severe injury at the same rate as the former. On the other hand, in respect of bodily injury, the number of reported cases has been rapidly increasing whereas the percentage of cases involving death or severe injury has been showing a decreasing trend, which implies that frequent occurrence of bodily injury cases involving relatively minor damage. As for extortion, the percentage of cases involving slight injury and the percentage of cases involving severe injury have been on a constant rise, along with the increase in the number of reported cases. The rate of victims injured seems to have increased due to the tendency of extortion being committed in a more violent manner; therefore, attention should be paid to the future trend.
