A puzzling social phenomenon has emerged in Japan: many post-00s youth publicly share syphilis infection experiences or draw fake rashes to show off online, with the epidemic growing severe in recent years.
A puzzling social phenomenon has recently emerged in Japan: many young people born in the 2000s have been openly sharing their experiences with syphilis on social media, and some young people who haven’t even contracted the disease have gone so far as to apply makeup to mimic the red rash associated with syphilis and post it online as something to boast about.

This is not some fictional, sensational story circulating online, but a situation that is actually unfolding in the region right now.According to publicly available statistics, the number of confirmed syphilis cases in Japan has exceeded 13,000 annually for five consecutive years. Currently, there is a shortage of penicillin—the drug of choice for the clinical treatment of syphilis—and the local public health system is facing a very serious challenge in responding to this infectious disease.
This situation did not arise suddenly; the related outbreak has been spiraling out of control since 2021: on the one hand, border crossings that had previously been closed due to pandemic control policies have gradually reopened, leading to an increase in imported cases among incoming travelers;on the other hand, Japan’s economy has been in a prolonged slump in recent years, with household income growth stagnating or even declining, leading some women in difficult circumstances to enter the gray-market service industry, which has further heightened the risk of virus transmission.
Many people still recall the article “The Rivalry at Summer Camp,” published thirty years ago. At the time, the piece portrayed Japanese children as role models who could endure hardships and follow rules, and it briefly became a benchmark for discussion among parents in China. Yet today, the fact that Japan’s younger generation views contracting sexually transmitted diseases as a badge of honor is a disturbing trend that cannot help but evoke a sense of sorrow.

Upon closer examination, the essence of this phenomenon extends beyond the scope of a public health crisis: a shift in young people’s sense of right and wrong and their perception of honor and shame, coupled with the public healthcare system’s inability to bridge the gap in drug supply and a lack of guidance on values for this demographic—these multiple factors have combined to create a significant breach in society’s defenses.
Health and stability are never just abstract concepts on paper; they mean that ordinary people do not have to worry about falling ill for no apparent reason in their daily lives, are not driven to the brink of despair by hardships, and do not lose their way amid negative social trends—and this is precisely what gives people the confidence to live secure lives.
In light of this phenomenon, we should also pay attention to the young people around us and guide them to establish clear moral boundaries, so that they can consciously resist the influence of various negative trends.
