The Sankebetsu Brown Bear Incident: The Worst Animal Attack Recorded in Pioneer History and the Terror of 'Failing to Hibernate'
Over the course of two days, seven people, including a pregnant woman and children, were mercilessly devoured, and three others were severely injured. This unprecedented beast attack thrusts profound psychological terror and the ruthless nature of the wild upon us today, unable to be dismissed merely as an “animal attack.”
1. “Ana-Motazu” - The Wandering of a Starving Behemoth
The primary culprit of the incident was a single, giant male brown bear known as “Kesagake” (Slash across the shoulder). According to records when it was finally killed, it possessed an extraordinary, monstrous physique, measuring 2.7 meters in length and weighing 340 kilograms.
Normally, brown bears confine themselves to dens and enter hibernation when winter arrives. However, individuals that fail to store enough nutrition for some reason are unable to hibernate and end up wandering through the snow, starving. They are referred to as “Ana-motazu” (Those without a den).
An “ana-motazu” is in a state of extreme starvation and becomes highly ferocious. The individual that attacked Sankebetsu was also frantically searching for “prey” to satisfy its madness-like appetite.
2. Learning the Taste and “Fragility” of Humans
The essence of the terror brought about by this bear lies not only in its overwhelming violence but in the fact that it “learned.”
By breaking into a pioneer’s house during the first attack and devouring a woman named Mayu Abe and a young child, the bear learned a decisive fact. That fact was: “Humans are creatures that cannot resist, are easy to catch, and furthermore, are delicious.” And the tragedy cascaded. The bear appeared again at the house where the wake for the first victims was being held. Even with a fire burning and many adults gathered with guns in hand, the bear smashed through the wall without flinching in the slightest, causing further casualties. Avoiding the lights, creeping from the darkness, and precisely hunting people—its terrifyingly high intelligence plunged the pioneers of that time into the abyss of despair.
3. The Purgatory of Screams and the Extermination
As vividly described in Akira Yoshimura’s non-fiction novel Gyuma-arashi (Bear Storm), the scene was truly a living hell. A pregnant woman screaming “Bite my throat and kill me” as her fetus was dragged out of her. A giant beast tearing apart fleeing people as if they were toys. The police and local extermination squads who rushed to the scene were utterly helpless against the bear’s dreadful vitality and speed.
The one who finally delivered the coup de grace to this incarnation of terror was Heikichi Yamamoto, known as a legendary bear hunter (Matagi). Until his single deadly bullet pierced the bear’s heart, the village of Sankebetsu remained completely dominated by the atmosphere of absolute death.
4. Awe Toward Nature and the Price of “Pioneering”
The Sankebetsu Brown Bear Incident is one of the cruel prices paid as a result of humans overestimating the shield of “civilization” and thoughtlessly stepping deep into nature. Toward the bear, humans were not the lords of creation, but merely “slow-moving, soft proteins” found in a world locked in snow.
Even in modern society, conflicts with wild animals, such as the appearance of urban bears or the Fukuoka University Wandervogel Club Brown Bear Incident born from a lack of knowledge, are unceasing. The tragedy of Sankebetsu is carved into history as a blood-stained lesson that must never be forgotten, as long as we continue to fear and hold awe toward the natural world.
