The Guardian:

The number of single people [in Japan] has reached a record high. A survey in 2011 found that 61% of unmarried men and 49% of women aged 18-34 were not in any kind of romantic relationship, a rise of almost 10% from five years earlier. Another study found that a third of people under 30 had never dated at all. (There are no figures for same-sex relationships.) Although there has long been a pragmatic separation of love and sex in Japan—a country mostly free of religious morals—sex fares no better. A survey earlier this year by the Japan Family Planning Association (JFPA) found that 45% of women aged 16-24 "were not interested in or despised sexual contact." More than a quarter of men felt the same way.
