A wave of fear has swept across social media following a tsunami prediction by Ryo Tatsuki, a former Japanese manga artist known for her dream-based prophecies. Tatsuki claims a catastrophic tsunami will strike in July 2025, boiling the ocean south of Japan and devastating countries like Taiwan, Indonesia, and the Northern Mariana Islands. Her claim, rooted in a dream rather than science, has gone viral, despite the lack of any supporting seismic data. Experts from Japan’s Meteorological Agency confirm there is no unusual activity in the region and no scientific basis for this prediction. Earthquake forecasting depends on measurable, real-time data—not visions or dreams.

Tatsuki gained notoriety after her 1999 manga The Future I Saw appeared to foreshadow Japan’s 2011 tsunami, earning her comparisons to psychic figures like Baba Vanga. However, many of her so-called accurate predictions, such as COVID-19 or Princess Diana’s death, have been either backdated or debunked as hoaxes spread by impersonators. Still, the psychological impact of her latest claim is real. Reports show travel bookings to Japan in July 2025 have dropped by as much as 50%, harming tourism and the local economy. Airlines and hotels are already experiencing losses. Even Tatsuki has advised against panic, stressing her dream should not be taken as a definite warning. The bottom line: science—not superstition—should guide our decisions. Japan remains safe, and no official warnings have been issued for the upcoming summer.
