Earthquakes can’t be predicted. But a manga artist’s dream of a July 5 'megaquake' has spooked some residents and travelers.

A manga novel has predicted that a mega-earthquake will hit Japan today, July 5. The 2021 reprint of 'The Future I Saw' by Ryo Tatsuki warns that a "huge" tsunami will wash over countries in the Pacific Ocean.

Viral rumours of impending disaster stemming from a comic book prediction have taken the sheen off Japan's tourism boom, with some airlines cancelling flights from Hong Kong where passengers numbers have plunged.
