According to the written confession of Taiji Ohno in November 1954, he was born in Kochi Prefecture, Japan in 1902. In December 1934, he volunteered to become a police service instructor of the "Manchukuo". In October 1938, he was dispatched to the Autonomous Government of North Shanxi. After Japan's surrender in August 1945, he took refuge in Yan Xishan's troops and served as colonel instructor of the Artillery Training Camp of Taiyuan Pacification Office. He was arrested on 12 December 1950 in Shanxi.
August 1935:captured many Chinese people from areas centered around Hengdaohezi and 20 of them were detained in Hengdaohezi Police Station and "tortured through beating, bloating them with water, binding and hanging, etc. Two of them were charged with strong anti-Japanese attitude, and were killed by Ishida, who toasted their heads and said the brains would be sent to Harbin as medicine. I ate one of them";
1936:in Zhuhe County, Binjiang Province, "joined the Depopulated Zone Working Team (i.e. the team to create depopulated zones, note by the translator) composed of 60 policemen headed by the Military Counselor of Zhuhe County". On 12 February 1936, Zhuhe County Office received two women. "One of them was Zhao Yiman, 27 years old". "I" "touched her bullet wound on the wrist with my hand or a whip, while interrogating her about the organization and contact relations of the Communist Party for nearly two hours";
From August 1936 to June 1937:organized a Baojia Self-defense Regiment and ordered the members to cut down the victims' ears as proof when killing soldiers of the Northeast Anti-Japanese United Army and ‘collaborators'. The Baojia Self-defense Regiment "killed 9 soldiers and staff of the Northeast Anti-Japanese United Army in Echeng County, and cut down the ears of 8 of them and the head of the ninth person, sending them to the County Office";
February 1937:"I saw an insane beggar aged around 40 outside the south gate of Echeng County, Binjiang Province, sitting there and looking very dirty". I ordered subordinate Japanese policemen to poison him by putting sub-arsenic acid in a steamed bun. On the next day, I heard the report that "the beggar ate it and was poisoned to death";
Around August 1937:in Yongzengyuan, Echeng County, Binjiang Province, I called a grain operator of the Northeast Anti-Japanese United Army to the interrogation room, "I personally interrogated him with a whip, and determined after about one hour's torturing that he was indeed an anti-Japanese element", "so I ordered Inspector Ito of the Police Department to kill him";
Around May 1940:in the county seat of Yingxian County, I saw about 20 Chinese who had been detained for over one year in the detention house of the Local Government. I instructed them to sentence these people in three ways: death penalty, fine or whipping. "I proposed that 5 of them were operators of the Eighth Route Army and should be sentenced to death for disturbing the order in the county". When the county magistrate told me that 3 of them had already been sentenced to death, I pretended that the proposal was made by the Chinese people. Later, the three people "were shot dead on the execution ground outside the south gate";
From 1935 to 1945:"killed a total of 654 Chinese people in 35 cases"; "I set fire to and burnt down a total of 47 households with 146 rooms in 3 cases"; raped 14 people in 9 cases; tortured 724 people in 37 cases, and plundered 64,000 tons of grain and 3,600 silver dollars in 36 cases".
