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

Manga artist Ryo Tatsuki wrote in her 2021 work ‘The Future I Saw’ about a crack forming beneath the sea between Japan and the Philippines, which she claimed would trigger a tsunami three times more powerful than the one in 2011.

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.
