Herbivore men

Herbivore men or grass-eater men (草食(系)男子, Sōshoku(-kei) danshi) is a term used in Japan to describe young men who become a voluntarily celibate and express little interest in getting married or being assertive in pursuing relationships with women.^[1] The term was coined by the author Maki Fukasawa, who initially intended for it to describe a new form of masculinity that was not reliant on the proactivity and assertiveness typically associated with masculinity in Japan. Philosopher Masahiro Morioka defines herbivore men as "kind and gentle men who, without being bound by manliness, do not pursue romantic relationships voraciously and have no aptitude for being hurt or hurting others."^[2] According to Fukasawa, herbivore men are "not without romantic relationships, but have a non-assertive, indifferent attitude toward desires of flesh."

The term was quickly sensationalized by the media, gaining a negative connotation suggesting young men who had lost their "manliness" were responsible for Japan's declining birth rate and stagnating economy. Through mass media, the label of herbivore man came to be associated with irresponsible, overly feminine men who cared too much about their appearance rather than marriage or finding a stable job, which were seen as traditionally masculine roles. The definition of herbivore men is still debated because of this, making it difficult to estimate how many men in Japan identify as herbivore men, particularly considering the social stigma associated with the term.

A similar term is carnivorous women (肉食系の女性, Nikushoku-kei no josei), denoting more sexually proactive and assertive women who are often considered maneaters with baby fever.^[3][4][5]
