( NewsNation) — Airlines in Japan are cancelling flights after a drop in sales linked to a manga from the 1990s that predicted a disaster. Artist and author Ryo Tatsuki published “Watashi ga Mita Mirai,” which translates to “The Future I Saw,” in 1999. She calls the book a dream journal and says it’s based on her recorded dreams.

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.

A powerful eruption has rocked Japan as Mount Shinmoedake explodes with ash and fear. Just days after a magnitude 5.5 earthquake, the volcano's dramatic blast has reignited panic over a chilling prophecy.
