Jeju Island is starting to feel the real-world effects of a wave of rumors surrounding missing persons cases and deaths circulating on social media. With the autumn tourist season approaching, domestic visitor numbers to the popular South Korean island destination have begun to decline.
According to the Seoul Economic Daily, reported Monday, August 31, 2026, the Jeju Tourism Association recorded a 1.9% drop in domestic visitors between August 1–29 compared to the same period last year. That’s a notable shift, up until mid-month, visitor numbers had actually been running slightly ahead of the previous year’s pace.
When the Decline Started
The turning point became clear around August 24, when the body of a man surnamed Jang was discovered after more than 100 days of being reported missing.
Comparing matching days of the week makes the drop even more visible. Between August 25–30, 2025, Jeju welcomed 213,706 domestic tourists. This year, over the equivalent August 24–29 window, that number fell to just 202,234, a drop of 11,472 visitors, or 5.4%.
The decline also grew steadily worse throughout the week: just 0.3% on Monday, then climbing to 4.5% on Tuesday, 5.3% on Wednesday, 4.9% on Thursday, and 7.6% on Friday. By Saturday, the drop had reached a full 10%.
More Than Just Seasonal Timing
Industry insiders say seasonal patterns alone don’t fully explain the drop. The Jang case reportedly reignited public interest in several earlier missing persons cases, which were widely shared and re-circulated online, fueling growing anxiety among prospective travelers.
That concern intensified further after four people were found dead on Jeju within a tight window between August 22 and 24.
On August 22, a man in his 60s was found dead in Gujwa-eup, a case that drew extra scrutiny after it emerged that his missing persons report may have been mistakenly closed by the same officer handling the Jang case.
A day later, a man believed to be in his 70s, previously reported missing, was found in waters off Jocheon-eup. On August 24, another victim was found dead near a valley in Aewol-eup. That same day, Jang’s body was discovered in Hallim-eup.
Then on August 29, the body of a serviceman in his 20s was found near the coast by Haye Port in Seogwipo. He had left home two days earlier carrying fishing gear and had since become unreachable.
Unrelated Cases, One Viral Narrative
Police have stated they believe there is no criminal element connecting these cases. But because the deaths surfaced in such close succession, several genuinely unrelated incidents began getting lumped together across social media and online communities. Unverified information and exaggerated claims soon created the impression that Jeju had become unsafe overall.
The narrative even picked up a nickname online, the “Jeju horror story.” That framing has understandably worried the local tourism industry. If the perception that all of Jeju is unsafe continues to spread, officials fear it could drive further trip cancellations and a slowdown in new bookings.
“We understand there have been a number of trip cancellations to Jeju following coverage of these cases,” one tourism industry figure said. “There hasn’t been large-scale cancellation yet, but if this situation continues, the autumn tourist season could be affected.”
Government Response
Jeju’s provincial government is urging the public not to spread unverified information and to remove content that has been proven false.
Jeju Governor Wi Seong-gon said rumors making the island appear more dangerous than other regions need to be corrected quickly. “Accurate facts and necessary information must be communicated promptly. We need to respond actively so unverified information doesn’t further amplify anxiety about safety in Jeju,” he said.
The provincial government plans to establish a dedicated response system and review how missing persons cases are handled, working alongside police, fire authorities, and civil society groups. Enhanced CCTV coverage and AI-based monitoring are also being prepared to strengthen public safety across the island.
What This Means If You’re Planning a Trip to Jeju
While the string of recent cases has understandably rattled public perception, authorities have found no evidence linking them or suggesting a broader safety threat to visitors. As with any destination facing a viral safety scare, it’s worth relying on verified official updates rather than social media speculation when deciding whether to proceed with travel plans.
