@RikaDerufu @LukeAlmighty It is given that violent crime is a near-zero factor, it makes sense that women are murdered more than men. This is because all the murderers you have left are insane people and assassins, the latter being effectively a non-factor.
When it comes to being attacked insane people, it is definitely easier for a man to defend himself, given his superior phyical strength, than it is for a woman.

Assuming that the mentally deranged attack men and women at a similar rate, it adds up that men survive these encounters about 25% more often than women.
To think that there is a culture of "kill all women" in the mind of all the mentally stable Japanese men is crazy, that stuff is reserved for Koreans.
