They need bigger junks, bigger pussies and boobs for women and bigger dicks for men that should solve the problem. Bigger = more= better

I always use Google Streetview.

Actually having lived in many places in Japan, I would say this is more a Tokyo thing than a national thing. My friends from Tokyo are in their 20s and the majority are virgins who always lament the opposite sex never liking them despite not trying at all themselves, whilst those from Okayama, Fukuoka, Okinawa, Hiroshima, Kagoshima, Aomori, Hokkaido etc. have been fucking since high school (I personally know three girls who had kids either in late middle school or during high school).

Kids are all over the place where I'm living at the moment (Kitakyushu), and I see plenty in Okayama when I visit, but when I spend any time in Tokyo you barely see any anywhere. Birthrates say so too, whilst the country as a whole (apart from Okinawa) is below replacement rate, Tokyo is ridiculous, having 1.06 kids/woman when the next lowest is like 1.3.

Others are right re sex education though, it's not a thing here really at all. When I was in high school they had a whole school assembly where one 60 year old woman gave a talk on how babies are made, and she had a purple felt penis and a green felt vagina to point out where things were. Didn't actually say anything about sex beyond that cum makes babies, before making one of the 'cool' baseball players go up and go elbow deep in the felt vagina to pull out a terrifying felt baby. That was the end of it. My fiance didn't even know oral was a thing until I tried to go down on her (when she was 19, in the west you know of that shit when you're in middle school, if not younger)

I'm pretty shitty at maths, but for the 18-34 male demographic, if 70% are single and 42% of those who aren't married are virgins, then even if we assume for the sake of argument that the 30% who aren't single are all married, we're still talking 42% of 70% being virgins, which still gives us a figure of 29.4%, an alarmingly high figure when you consider 18-34 is usually a demographic is when most men and women are in their sexual prime.

True, it's not quite the "nearly half" the Daily Mail ran with as their headline but again, still a dire statistic.

Also, a "National Fertility Survey" isn't going to be polling preteens asking how much sex they're having.

Exactly it isn't, which is why I think the figures have been fucked with even more to give us that headline, while it looks like it serves no purpose if list the actual ages of the survey then it should be more accurate. To include people in the ages of 0-18 by using terms like "people under 40" you allow yourself more room to fluff figures to suit a dramatic headline.

You could well be correct in which people are being polled but that doesn't mean those numbers aren't being used for the headline is what I mean, say if you get the results from the survey and it tells you that 25% of people from 20-40 are virgins, that isn't a huge headline is it? but as you've done yourself you can deduce that the survey wasn't done on anyone under the age of consent because they are going to be presumed to not be having sex so the can still be added into a result if you want to as 100% virgin it's just when the headlines are pushing the below 40 mark I'm always skeptical because it allows them room to add in extra multiplying factors which make the headline more.... headliney.

Lets say you ran a survey to see how many men had 1 testicle instead of 2, you survey a large range of males and find that the number is slight say .... why did I get into this line lol but https://en.wikipedia.org/wiki/Monorchism yeah it's a thing it happens but if the figures from that were remotely high say 5% it still wouldn't give you a great headline, but it could still be manipulated into a grand headline given that injury and testicular cancer are reasons for the removal of them if you wanted to suggest the situation was far more common you could pose the results of your scenario that the % of men with 1 or fewer gradually increased with age, in fact by the age of 60 over 50% of all people are missing one or both testicles. Dramatic increase, now it has eyebrows raised... by the age of 60 you might have lost a testicle! Now you're clicking and talking about it. The reality is the wording has been altered, 50% of people of all ages are missing testicles, they're called women, they don't need to be surveyed to include them in the people who are missing said part of the body but if you phrase it as I've done above no misinformation has been done by me, simply inclusion of people I know to be on the side of the scale that I want to represent as being larger than it is.

I'm just saying, never look at the headline from a survey  like this and skip over an "oversight" such as including the ages 0-18, very rarely are figures omitted or submitted to a survey analysis unless they're there for a good reason.

Well If I wasn't married I would go there to help the japanese girls lose their virginity.

Japan is a doomed country, the economy died over 3 decades ago, and is maintained alive as a zombie thanks to negative interest rates and stock/ETF buying programs by the BOJ. Add to the economic disaster created and mainteined by their central bank, the population is decreasing, which means there are less new people able to work and pay for the social security of the retired.

Does Japan know about eating ass?

Earth isn't over populated yet.  We have tons of untapped resources and we don't take advantage of engineering insights that would further reduce scarcity. 

The population is so high that entire species of animals are going extinct and the climate is changing. None of these things should be happening. We are definitely far overpopulated.

Although the sex lives of the Japanese, where they have high access to education and birth control, is definitely not a factor. The economic situation is going to impact population growth in a country like that more than anything. The idea that they aren't having sex... that's just depressing, sex is as much a part of a healthy lifestyle as healthy eating or hygiene.
