According to the Statistics Portal, from 2008 to 2017 the number of men who committed suicide in Japan, per 100,000 people, was as follows: 36.6, 37.6, 35.8, 33.7, 31.1, 30.3, 28.1, 27, 24.5, and 24. The number of women who committed suicide during these same years in Japan, per 100,000 people, was as follows: 14.3, 14.3, 14.3, 14.8, 13.1, 13, 12.3, 11.3, 10.4, and 10.
Clearly, Japanese men commit suicide in rates almost three times higher than women. But, thankfully, the rates are going down and will hopefully continue to do so.
