It began as a murmur on niche internet forums—an ominous whisper about “boiling seas” and a foreboding warning of disaster. The voice belonged to Ryo Tatsuki, a former manga artist whose prophetic visions now have millions raising an eyebrow—and a passport.Supporting her eerie track record, Tatsuki’s The Future I Saw (originally published in 1999, reprinted in 2021) famously predicted the March 2011 Tōhoku earthquake and tsunami. That uncanny detail vaulted her into the spotlight as Japan’s “new Baba Vanga”Now, as July approaches, anxiety is rising again. This time, Tatsuki envisions a seismic catastrophe: a “boiling” ocean, possibly triggered by an undersea quake along the Pacific Ring of Fire. The projected epicenters stretch from Japan to Taiwan, Indonesia, even Hawaii—areas already known for tectonic instability .

These once-obscure predictions have now begun to influence real-world behavior. According to Reuters, tens of thousands of travelers from Hong Kong, China, and Taiwan have canceled their trips to Japan, fearing a July 5 calamity. Airlines and travel agencies have reported sharp drops in bookings—despite reassurances from Japanese officials urging calm .Meanwhile, Japan has seen more than 1,000 minor tremors near the Tokara Islands since late June, including a notable quake registering just below magnitude 6.0 on July 4This seismic swarm has revived fears that a much larger event—like a Nankai Trough megaquake—might be looming. Historian records and government data show the Nankai region has produced massive quakes every 100–200 years, and experts now estimate a 75–82% chance of such an event within the next 30 yearsScience vs. SpeculationNevertheless, Japanese authorities are urging restraint. A top seismologist from the University of Tokyo dismissed any direct connection between the recent tremors and a looming megaquake—there’s no concrete evidence linking them .
