Japan Family Planning Association conducted a survey and about 50 percent took participation of between 16 and 49 age. They told that they do not have sex from past month. Respondents gave a number of reasons for not having sex for long. 21.3% of married men and 17.8% married women said they get tired from work, and 23% of married women said sex was "bothersome" and 17.9% of male respondents said they had little interest (or a strong dislike) of sex.

Furthermore, a 2011 report from Japan's population center cited by Max Fisher at The Washington Post states:

• 27% of men and 23% of women aren't interested in a romantic relationship'
• From ages 18 to 34, 61% of men and 49% of women aren't involved in a relationship
• From ages 18 to 34, 36% of men and 39% of women have never had sex


Experts Believe that this is due to a highly developed economy and high gender inequality. This is causing the decrease in Japanese population which needs to be improved soon. There is a need to change the working culture, experts say.

The Japanese government has come up with support for Japanese people willing to have babies. Japanese Prime Minister Shinzo Abe's wants 80% of fathers to take paternity leave, same as mothers taking maternity leave and to take more support for childcare. One economist also recommended a "tax on the handsome" to make geeky guys more attractive to women.

Like, Japan there is a similar demographic problem that exists in Denmark also.
