Fear often spreads more rapidly than facts, particularly online. A wave of anxiety has emerged due to a dream-based prediction made by former manga artist Ryo Tatsuki. She claims a catastrophic tsunami will strike in July 2025, causing the ocean south of Japan to “boil” and devastating several Asian nations. Despite this alarming vision, there is no scientific support backing her forecast.

Tatsuki became famous after her 1999 manga The Future I Saw was believed to have predicted the 2011 tsunami in Japan. This led some to compare her to Baba Vanga, a mystic known for controversial predictions. In her latest claim, she outlines a massive tsunami striking a diamond-shaped area that includes Japan, Taiwan, Indonesia, and the Northern Mariana Islands.

Although lacking scientific validity, Tatsuki’s statements have gone viral, triggering widespread fear. Travel agencies have reported up to a 50% drop in bookings for Japan during July 2025. Airlines and hospitality industries are experiencing early financial impacts as tourists cancel or avoid trips to the region.

Skepticism is growing over Tatsuki’s so-called “accurate” predictions, many of which surfaced only after related events occurred. Notably, her supposed forecast of COVID-19 was actually lifted from a Dean Koontz novel. Some claims have also been attributed to online impersonators, casting further doubt on her credibility.

Experts and Japan’s Meteorological Agency confirm that no abnormal seismic activity has been detected. Earthquake predictions rely on scientific data—not dreams. Tatsuki has even advised people not to panic. Ultimately, Japan remains safe, and decisions should be informed by facts rather than fear-driven myths.
