Japan's Most Terrifying Bear Attack Becomes a Manga: Kuma Arashi Begins Serialization

One of Japan's darkest and bloodiest true stories, the Sankebetsu Brown Bear Incident, is coming to life on the pages of manga. The 1977 masterpiece Kuma Arashi (Bear Storm) by renowned author Akira Yoshimura began serialization on Shinchosha's digital platform Comic Bunch Kai on May 15, 2026, featuring stunning illustrations by Cathy Kato. To celebrate this exciting launch, the publisher has made the first 100 pages of the series available to readers completely free of charge.
The story is based on real events that took place in the snowy forests of Hokkaido in 1915, recorded as the deadliest wild animal attack in Japanese history. This tragedy, which resulted in a giant brown bear attacking a small settlement and killing seven people, was penned by Akira Yoshimura in the style of a "documentary novel." Yoshimura's work, which explores human nature and helplessness, now gains visual depth through Cathy Kato's detailed and atmospheric drawings. The manga is not just a horror story, but also a gripping period drama that depicts the relentless struggle of humans against nature.
The name behind this adaptation, Akira Yoshimura, is known as one of the most respected figures in Japanese literature. The author, who passed away in 2006, was particularly known for his works in which he meticulously researched and fictionalized real events. Illustrator Cathy Kato is seen as one of the most fitting choices to capture this heavy and dark atmosphere. The platform where the series is published, Comic Bunch Kai, was established in 2024 as part of Shinchosha's digitalization strategy and has been delivering "bone-deep" stories ever since.
