Flight reservations to Japan from some of its key tourism markets have reportedly plummeted, with some linking the fall to The Future I Saw, a Japanese graphic novel based on the “prophetic” dreams of its author, Ryo Tatsuki.

The cover of the original, published in 1999, refers to a “great disaster” occurring in March 2011 – the date Japan experienced a deadly earthquake and tsunami. In a new edition containing additional material that was published in 2021, Tatsuki said the next major disaster would occur on 5 July 2025. Her claim has fuelled sensationalist social media posts warning people to stay away from Japan.
