I. Type of statistical materials

Statistics, figures, tables and other calculated data are provided by the following bureaus/department of the Ministry of Justice; Judicial System Department of Minister's Secretariat, Criminal Affairs Bureau, Correction Bureau, Rehabilitation Bureau and Immigration Bureau. Data are also obtained from various researches and surveys conducted by relevant agencies, as well asfrom the following official statistics.


II. Coverage of statistical materials

Statistical materials available by the end of July 2015are used to record the figures up to the year 2014.

Those 2014 data yet available from official publication at the time of drafting this edition of the White Paper on Crime are based on the raw data offered by relevant agencies. As these data are provisional in nature, if the data in the subsequent official publication differ from this Paper, subsequent edition will make corrections as necessary. The same applies in the case of any change made within the official statistical publications.


I. Numbering of figures and tables

The numbering of figures and tables is indicated in the order of the Part, Chapter and Section (for example, Fig. 2-4-3-1 indicates Figure 1 of Section 3, Chapter 4 and Part 2) of this English version of the White Paper on Crime 2015 and does not necessarily correspond to the numbering of figures and tables in the full text of respective Japanese version.

II. Presentation of values, etc.

1. Numerical values, etc. in tables are presented as follows:

2. Numerical value in figures are presented as follows:


The proportion and percentage, etc. are rounded off to the first decimal places. Therefore, the sum of the composition rates 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, this Paper first subtracts 7.53 from 12.76 and then rounds off the value 5.23 to obtain the result of 5.2, not subtracting the rounded off value of 7.5 from the rounded off value of 12.8 (which yields 5.3.).
