Why Are the Japanese No Longer Interested in Sex?

From the Guardian:

Japan’s under-40s appear to be losing interest in conventional relationships. Millions aren’t even dating, and increasing numbers can’t be bothered with sex. For their government, “celibacy syndrome” is part of a looming national catastrophe. Japan already has one of the world’s lowest birth rates. Its population of 126 million, which has been shrinking for the past decade, is projected to plunge a further one-third by 2060.


The number of single people 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.

 The article contains a number of speculations as to cause, well worth reading. At least the Malthusians will be happy.

    Is it that they are no longer interested in sex or no longer interested in marriage and children?

        I read that part but feel that admitting something like this isn’t part of their culture. Most Japanese ( as far as I know) live at home until marriage. It isn’t like you can bring a partner home under those conditions. Going to a hotel might be too shameful or too much effort. They probably just don’t want to be married or have children. They might be interested in sex without marriage but are too ashamed to admit it.

        “Most Japanese ( as far as I know) live at home until marriage.”
        Most women live at home, less true for men.

        ” Going to a hotel might be too shameful or too much effort. ”
        No, Japan has made that easy. Sex hotels, exist rentable by hour or night. Shame about sex in Japan is weird, in some ways they have none in others they have a lot, but the distinction makes little sense outside of Japan.

      The numbers clearly show they are no longer interested in either. They seem to be more interested in inventing robots capable of relationships.

        have predicted that one major driver of sentient AI will be the desire for working women in places like Japan to have children without getting hit with a lifetime career penalty flag. AI children would be far easier to raise them meat children and would be able to contribute to the nation’s wealth once mature without nasty issues like healthcare costs. It’s pure win and when faced with massive depopulation countries like Japan and Russia will be happy to ignore any ethical or religious taboos.

    Couldn’t this survey be a bit skewed due to the strong cultural mores of Japan. There is a probably a strong tendency to self censor in a way that is deemed “appropriate” according to the norms over there. I realize the survey shows change too – perhaps the culture has become more prudish?

    A “long-time” reader of this blog after I read the Freakonomics book and ran across the blog last year.

    I live in Japan, and there are a lot of reasons why Japanese people, in general, have less intimacy and fewer children than Americans. Yes, there are some culture things, self-censorship, and so on.

    One of the biggest reasons, though, is similar to what is happening to China and other places where traditionally repressed women are starting to have careers and opportunities. There’s simply no desire to settle down and have kids when there’s so much to do. Add in all the overtime Japanese do, the stresses of a high-context/low-individuality culture, and it’s easy for Japanese men and women to not want relationships.

    The cost of having children, too, may be relatively higher than that in western cultures. The government pays for childbirth, gives a subsidy for children, pays for children’s health care, and has networks of daycares and preschools, but children are a huge financial burden–one of mine is on its way, and thinking about all the supplementary lessons, daycare activities, and so on is a big headache. Most women quit work to take care of children, which is often necessary, and a lot of women don’t want to sacrifice their careers for that nowadays.

      The cultural pressures on women that you describe sound similar to reasons I’ve heard cited for the low birthrate in Italy and some other European countries. If women want careers and are still expected to take care of their husbands, why get married?

      I might point out though, that having sex is not the same as having children, or marriage. It’s also quite possible to be interested in sex, yet be unable to find acceptable, willing partners. Particularly in a shame-based culture, it might be less embarassing to falsely claim a disinterest in sex, rather than admit to an inability to find a partner.

    So… the article title is: Why Are the Japanese No Longer Interested in Sex? The article doesn’t try to even answer this or am I missing something? It just gives stats as to the fact they don’t like it but no answers as to why.

      I think that kind of was the point of the article. Give you the stats and leave you with the question.

    Soy? I’ve read they give it to prisoners after finding that it kept them calmer, theory was that it reduced testosterone levels.

    The headline is biased and loaded: “Why Are the Japanese No Longer Interested in Sex?”

    Why should they be interested in sex? Who says? Why do we think that way? Is it somehow aberrant not to be interested in sex?

    I do understand that the article is about a downward trend, so I get it. But maybe many Japanese people are realizing that finding and maintaining a relationship that includes sex is simply a helluva lot of work and a near total loss of autonomy for a reward that is very fleeting. You have to give yourself permission to think about that, because it is heretical in Western culture — at the moment.

    Hot debate. What do you think? Thumb up 13 Thumb down 10

      Considering that procreation is tantamount to the survival of a species, yes, yes it is aberrant.

      Pretty much by definition to.

        Hi Anonymous0: The article is about sex, relationships, romance: not the very occasional coitus required to procreate. Aberration? 60% of young Japanese men (a very significant MAJORITY) and 49 % of women are in no relationship at all — and a third have NEVER dated — and the ratio of sexless young people is GROWING. Therefore, not aberrant, “by definition” to use your unsupported phrase.

        BTW, what definition?

        I stand by what I wrote: A sexual relationship comes at a very high opportunity cost and I can see how some would choose other paths, including the growing majority of Japanese under 34.

    Why, a weird mix of old and new cultural norms/responsibilities/and expectations which don’t work together.

    The old way was children were coddled at home and pressured in school. You were a child until married. Men worked like crazy (responsible to provide $ for family) out of the home, women worked like crazy in the home(responsible to take care of family, both children and elderly). Children were pressured to get married. (to the level of arranged marriages) Enter feminism, women’s responsibilities change a lot, Men’s mostly still don’t.

    So you have single young women, parents will not hint at her leaving home until she is married. Until then she lives rent free, has Mom as a live in maid, and any $ she earns she spends on herself. She sees how hard her mother works, (for her) and doesn’t want it. If she likes to work, she can; if she doesn’t she only needs to a little for extra spending money.
    Single men, are coddled at home till they hit adult age, then (married or not) pressure and drive to work and to succeed. He gets hints to move out. Access to porn other sexual things and pretty much no social or religious stigma against it, makes it a fine substitute for women/dating/relationships. Either living at home or on his own, little pressure to get married, and little reason to, since the mans side is a raw deal
    10-20 more years when the parents generation reaches the age where they need the kids to take care of them, will be interesting.
