*The source counts the answers of the survey conducted in December 2024 as figures for fiscal year 2024. The Japanese fiscal year starts on April 1 of the stated year and ends on March 31 of the following year. Figures for previous years are based on earlier surveys.
**Figures are based on diary entries of 899 respondents. Answers represent the average usage time of two weekdays, which is why the sample size is indicated as 1,798 respondents. From fiscal year 2024 onward, the number of respondents increased because of the inclusion of an additional age group (men aged 70 to 79 years old).
Data prior to fiscal year 2024 come from previous reporting.
Sample size of earlier surveys:
FY 2015 n=1,512
FY 2016 n=1,512
FY 2017 n=1,514
FY 2018 n=1,514
