According to the Japan Times, the media and social networks are spreading the comic book by artist Ryo Tatsuki.
Specifically, in the book "The Future I saw", author Ryo Tatsuki describes a major Tsunami that will sink Japan on July 5 this year.
Previously, in a book published in 1999, author Ryo Tatsuki correctly predicted the 2011 earthquake in Japan.
Therefore, many people believe that the book is a prediction of the upcoming disaster.
The work "The Future I saw" is based on a dream in which a Tsunami submerged Japan and affected surrounding countries.
In a February report by the Japanese government's earthquake prevention and control force, they have been monitoring seismic activity along the Nankai drain for long periods and forecasted a major earthquake risk with a Tsunami greater than 30 meters over the next 30 years to about 80%.
In addition, feng shui scholar Qi Xian Yu, nicknamed Master Seven, also called on everyone to limit travel to Japan from April this year.
Some Japanese and East Asian exotic experts have also issued similar warnings, making the online community more worried and skeptical.

Online speculation is also affecting Japanese tourism.
According to Bloomberg Intelligence's analysis of Forward Keys data, the number of air bookings from South Korea, Taiwan (China) and Hong Kong (China) has decreased since April, with the number of bookings from Hong Kong (China) decreasing by an average of 50% compared to the previous year.
The number of bookings from late June to early July to Japan also decreased sharply by 83%. Greater Bay Airlines and Hong Kong Airlines (China) have both cut some flights to Japan this month.
Yoshihiro Murai, Governor of Miyagi Prefecture, said that last month, rumors began to affect tourism.
The meteorological agency emphasizes that current science cannot predict high-precision earthquakes.
Japan's location within the Ring of Fire, an area of active tectonic activity surrounding the Pacific Ocean, makes it one of the world's most seismically active countries.
Japan's most recent major earthquake was in 2011, causing a devastating song than and nuclear disaster in Fukushima.
However, overall, Japanese tourism is still vibrant. In April, Japan recorded a record 3.9 million foreign tourists coming to visit the resort.
"The earthquake speculation is certainly having a negative impact on Japanese tourism and will slow the development for some time," said Eric Zhu, aviation and defense analyst at Bloomberg Intelligence.
Zhu predicts many airlines will face difficulties in the next few months based on the current booking model and the expected number of flights.
In particular, Cathay Pacific Airways may face financial risks because the airline has a close connection to the Japanese tourism market.
