Herbivore men

Herbivore men 草食系男子 (Sōshokukei-danshi), or grass-eating men, is a Japanese term to describe the asexuality and personality traits of men who are "generally passive toward relationships and attracted to pastimes traditionally attributed to females." This term was created in 2006 and became a buzz word in 2008-9. Several books on herbivore men were published during this period.

A Japan Times poll stated that over a third of Japanese men aged 16 to 19 had no interest in sex, double the figure from 2008, and over 40 percent of married men had not had sex for a month or longer.

This phenomenon has yet to be officially documented in other Asian nations, but the increase in feminized men has spread over much of Asia along with Japanese culture. In China the first report on Japanese herbivore men appeared in the state media Xinhuanet on December 1, 2008, and Masahiro Morioka's book Lessons in Love for Herbivore Boys was translated into Traditional Chinese in 2010 in Taiwan. Japan and the Four Asian Tigers have had plunging birthrates. In 2010, Taiwan set all time record low fertility rate at 0.91 per woman, less than the half replacement level of 2.1.
