Japanese adults have their first heterosexual sexual experiences later than their counterparts in the United States and the UK, according to a new study.
The study found that sexual inexperience was on the rise in Japan, with the percentage of women aged 18 to 39 who’d never had sex rising to 24.6% in 2015 from 21.7% in 1992. The change was greater for men of the same age, with 25.8% virgins in 2015, up from 20% in 1992.
By comparison, surveys from the UK, the United States and Australia suggest that rates of heterosexual inexperience are between 1% to 5% of adults in or around their 30s. The study said Japan appears to be an outlier.
The results are likely to be cause for concern given Japan’s ongoing battle with population decline and a low fertility rate. The issue is important in Japan because it is considered a "super-aged" nation, meaning more than 20% of its population is over 65 years old.
