December 9: Ōta family On December 9, 1915, at 10:30 a.m., the giant
brown bear turned up at the home of the Ōta family. Abe Mayu, the farmer's wife, and Hasumi Mikio, a baby being cared for by Mayu, were at the house. Mikio was bitten on the head and killed. Mayu fought back, apparently by throwing firewood, and tried to escape. She was overtaken, knocked down, and dragged into the Imperial Forest of Sankebetsu. According to contemporary descriptions, the scene resembled a slaughterhouse, with blood puddled on the farmhouse floor.
December 10 Search Early in the morning, Saitō Ishigorō and Miyoke Yasutarō left the village on errands. Meanwhile, a thirty-man search party was organized to capture the brown bear and recover the remains of Mayu. Entering the forest no more than , it met the bear. Five men shot, but only one managed to land a hit. The enraged animal retreated, and the men escaped injury. After the bear fled, the
hunters scouted the area and discovered dried blood on the snow at the base of a
Sakhalin fir tree. Beneath the snow was the corpse of Mayu with only the head and parts of the legs remaining. The bear had stashed the body of Mayu in the snow in an attempt to preserve it, as well as to hide it from scavengers: proof it was this brown bear in the attack.
Return to the Ōta farm The villagers believed that once the bear had a taste for human flesh, its return to the settlement was assured. Villagers gathered at the Ōta family's home with guns. Around 8:00 p.m. that night, the bear reappeared. Although the villagers had anticipated the bear's return, they were nonetheless panicked by it. One man did manage to shoot at the bear. By the time the corps of 50 guardsmen posted away at the neighboring Miyoke house arrived, the bear had vanished into the woods. The corps reassembled and headed downstream on what was thought to be the bear's trail.
Miyouke family When news of the Ōta family attack was first received by the Miyouke family, women and children sought refuge there while guardsmen patrolled outside. The guardsmen were having dinner when news of the bear's return to the Ōta farm reached them, and they marched off. The bear, having escaped death at the Ōta house, now fled to the Miyouke homestead. Yayo, Miyouke Yasutarō's wife, was preparing a late meal while carrying her fourth son, Umekichi, on her back. She heard a rumbling noise outside, but before she could investigate, the bear broke through a window and entered the house. The cooking pot on the hearth overturned, dousing the flames, and in the ensuing panic the
oil lamp was extinguished, plunging the house into darkness. Yayo tried to flee the house, but her second son, Yūjirō, clung to her legs, tripping her as she ran. The bear attacked her and bit Umekichi. Odo had remained at the house as the only bodyguard. When he ran for the door, the bear released the mother and child to pursue him. Yayo then escaped with her children. Odo attempted to hide behind furniture but was clawed in the back. The bear then mauled Kinzō, the third son of the Miyouke family, and Haruyoshi, the fourth son of the Saito family, killing them, and bit Iwao, the third son of the Saitō family. Next to be targeted was Take, Saitō Ishigorō's pregnant wife. She too was attacked, killed, and eaten. From later testimony, villagers heard Take begging the bear not to touch her belly but instead to eat her head. The guardsmen who had tracked the bear downriver realized that they were not, in fact, on its trail. As they hurried back to the settlement, a seriously injured Yayo met them and related news of the attack at the Miyouke family's house. The corps raced there to rescue any survivors. When they arrived, the house was dark but sounds of an attack emerged. Believing that the bear had killed everyone inside, some of the guardsmen proposed setting the house on fire. Yayo, hoping that some of the children still lived, forbade this. The guardsmen were divided into two groups: one, consisting of ten men, stood guard at the door while the other group went to the back of the house. When given a signal, the group at the rear set up a racket, shouting and rattling their weapons. As expected, the bear appeared at the front door. The men there had bunched up, with lines of fire blocked by the guard at their head, whose own rifle misfired. Amid the general confusion and risk of crossfire, the bear escaped into the night. Carrying torches made of birch bark, they entered the house and beheld the results of the attack. Rikizō and Hisano, first son and daughter of the same relatives, were injured but lived. The village people gathered in the school, and seriously injured people were accommodated in the Tsuji family house near the river. After the incident, only veterans of the
Russo-Japanese War remained at their posts.
Yamamoto Heikichi and "Kesagake" Meanwhile, Saitō Ishigorō, unaware of his family's fate, filed a report with authorities and the district police before returning to Tomakomai and lodging at a local hotel there. Miyouke Yasutarō had heard that a local man named
Yamamoto Heikichi was an expert bear hunter and so paid a visit to his house. Yamamoto was certain that the bear was the dreaded man-eater he nicknamed or "the diagonal slash from the shoulder", a white pattern from the back to the chest, which had previously been blamed for the mauling and deaths of three women in a neighbouring village, but by now he had pawned his gun for money to buy alcohol and he refused Miyoke's request for aid. Unable to return home, Yasutarō stayed in Onishika (now
Obira).
December 11 On December 11, Miyoke Yasutarō and Saitō Ishigorō returned to Sankebetsu. Noticing the villagers gathered at the branch school, the two pieced together the story of the mauling. A group of men, including Miyoke and Saitō, were formed to kill the bear. Believing that the bear would reappear, they decided to wait for the bear at Miyoke's residence, but the night passed with no attack.
December 12 The news of the bear's appearance in Sankebetsu reached the Hokkaido Government Office, and under the leadership of the Hoboro (now
Haboro town) branch police station, a
sniper team was organized. Guns and volunteers for the team were gathered from nearby towns, and after getting permission from
Teishitsu Rinya kyoku (the "Imperial Forestry Agency", now ''
Rin'ya chō''), the team went to Sankebetsu that evening. Chief Inspector Suga, the branch office commissioner, went up the Rokusen-sawa with the aim of viewing the Miyoke family house and assessing the state of the sniper team and met all those who got off the mountain pass. The brown bear did not appear on December 12. It was decided that the bear would most probably try to retrieve the bodies of those it had killed, but there were no remains in the Miyoke family house. Therefore, a new plan was proposed: to attempt to lure out the bear with the corpse of a victim. The plan was widely condemned, especially by the Ōta, Saitō, and Miyoke families, but it was decided that for the future of the village it was the best plan. Within the day, the strategy was executed. The six-member sniper team (which now reluctantly included Yamamoto Heikichi) waited inside the house, but the bear stopped, appeared to check the inside of the house, and then returned to the forest. The bear did not appear again that night, and so the plan ended in failure.
December 13 At dawn, a search team discovered that the Ōta family's house was ransacked. The bear had eaten the people's winter food stockpile and ransacked the houses. The bear had damaged at least eight houses, but so far no one could find it. The police captain, Suga, motivated the men by cheering from the village outside. Given that there were now 60 armed men, it was decided that they should hunt in the surrounding mountains. Kesagake now seemed to lack prudence and stretched its territory downstream. Suga recognized the increasing risk of the situation. He made an ice bridge as a line of defense, then arranged snipers and guards. That night, a sniper at the bridge thought he saw something in the shadows of the tree stumps on the opposite shore. Receiving this information, Suga thought it might be a man's shadow. When he spoke to it, however, he received no reply and ordered the snipers to open fire. At that moment the shadow, apparently that of the bear, disappeared into the forest. They were disappointed, having failed to kill the bear, but the captain thought he had heard some response from it.
December 14 The next morning, a team investigated the opposite shore and found a bear's footprint and blood there. Given that Kesagake had again been wounded, and that imminent snowstorms were threatening to cover any tracks, it was decided that this was the most critical opportunity to hunt down and kill the bear. Yamamoto and Ikeda Kamejirō, a guide, immediately set out after the bear. Yamamoto decided to track the bear with a team of two, as it would be quicker than a larger team. Yamamoto was familiar with Kesagake's behavior and successfully tracked him down. He spotted the bear resting near a
Japanese oak. Approaching to within 20 meters of the bear he opened fire. The first shot hit the bear's heart and the second hit its head, fatally wounding the animal. When measured, the bear was unique: and tall, dark brown with golden fur, the head unusually large compared to the rest of the body, and estimated adult age about 7-8 years old. A necropsy was carried out on the bear, during which parts of his victims were found in his stomach. It is said that the villagers dismantled, boiled, and ate it as revenge for the victims who had been devoured. While at the time the skull and some of the fur of the bear were kept, they later were lost. == Aftermath ==
