Data are also obtained from various researches and surveys conducted by relevant agencies, as well as from the following official statistics.

   (Judicial System Department, Minister’s Secretariat, Ministry of Justice)

– Annual Report of Statistics on Correction
   (Judicial System Department, Minister’s Secretariat, Ministry of Justice)
– Annual Report of Statistics on Rehabilitation
   (Judicial System Department, Minister’s Secretariat, Ministry of Justice)

[Notes]
(1) Crime Statistics by National Police Agency was entitled “Crime Statistics” until 1963 and renamed “Crimes in 19xx (various years)” in 1964. For the purpose of this paper, both of them are referred to as “Criminal Statistics by National Police Agency.”
(2) The statistical data up to 1972 do not include the data of Okinawa Prefecture until May 14, 1972.
(3) All data sources are indicated using the names of ministries and agencies after the reorganization of central government ministries and agencies in January 2001.

2. Coverage of statistical materials
  Statistical materials cover the period up to 2008 and available data at the end of July 2009.
  For those statistical data for 2008 that were not available in form of official publication at the time of drafting, raw data offered by relevant agencies were used. Those data are provisional in nature and may differ from the corresponding data in the subsequent publication. In such cases, the relevant figures will be corrected in the White Paper on Crime for the coming years. In addition, the same correction will be made with any change within the official statistical publications.

III. Presentation of Figures and Tables
1. Numbering of figures and tables
  The numbering of figures and tables are indicated in the order of the part, chapter, section (for example, Fig. 2-4-3-1 indicates Figure 1 of Section 3, Chapter 4, Part 2).

2. Presentation of values, etc.
(1) Numerical values, etc. in tables are presented as follows:
(i) “–” zero in number or not applicable or the percentage thereof
(ii) “0” number that does not reach one when rounded off
(iii) “0.0” proportion that does not reach 0.1 when rounded off
(iv) “…” data/statistical materials not available, or when the parameter is zero
(2) Numerical value in figures are presented as follows:
(i) “0” zero in number or not applicable
(ii) “0.0” proportion that does not reach 0.1 when rounded off

IV. Others
1. In the White Paper on Crime, “treatment” refers to treatment that persons cleared by police or other investigative authorities receive at each stage of prosecution, trial, correction, and rehabilitation.
2. Calculation method
  The proportion and percentage, etc. are rounded off. Therefore, the figures for proportion may not add up to 100.0.
  In addition, the sum or difference of each proportion is calculated by first adding or subtracting values and then rounding off the resulting value. Thus, the value may not match the value calculated by first rounding off each value and then adding or subtracting rounded off values.
  For example, when calculating the difference between 12.76 and 7.53, the result 5.2 obtained by first subtracting 7.53 from 12.76 and then rounding off the value 5.23 does not match the result 5.3 obtained by subtracting the rounded off value of 7.5 from the rounded off value of 12.8.
