Khabarovsk Trial exposes Japan's bacteriological warfare during WWII: Russian historians

The Khabarovsk Trial, held in Russia's Far East city of Khabarovsk 76 years ago, holds far-reaching significance as the only post-war military tribunal dedicated entirely to Japan's bacteriological weapons program and related human experiments at its notorious and top-secret army units, such as Unit 731, during World War II, according to Russian historians.

From Dec 25 to 30, 1949, 12 former members of the Japanese Kwantung Army were tried in Khabarovsk, charged with developing and testing bacteriological weapons and carrying out inhuman medical experiments during WWII.

Recordings of the trial, lasting 22 hours, five minutes and 57 seconds, contain contents concerning the transformation and organization of Unit 731, as well as the live human experiments, field toxicity tests, preparation and implementation of germ warfare by the unit.

In 1935, the invading Japanese army established Unit 731 in the city of Harbin in northeast China's Heilongjiang Province as the nerve center for its biological warfare. At least 3,000 people were used for human experiments by Unit 731, and more than 300,000 people in China were killed by bacteriological weapons.

Inside the building located in Khabarovsk's city center where the trial took place in 1949, an exhibition hall displays the evidence of Japan's biological and chemical warfare, including old photos of the 12 Japanese military members standing trial.

"The defendants, those who carried out the will of their superiors, stated that they were taught to treat the test subjects not as human beings, but as 'logs', as inanimate objects," said Stanislav Slivko, a Russian expert in historical sciences, who like many other Russian historians, believes the Khabarovsk Trial is one the most important military trials held after WWII.

All 12 defendants were convicted of war crimes such as manufacturing and using biological weapons. However, as the Soviet Union had abolished the death penalty at the time, they were eventually sentenced to prison terms ranging from two to 25 years.

Yuriy Pikalov, a professor at Russia's Pacific National University, said the Khabarovsk Trial holds important historical lessons that crimes against humanity such as those committed by Unit 731 never go unpunished.

"The Khabarovsk trial of December 1949 holds great moral significance. The lessons of history, of the past -- that such crimes do not go unpunished -- are very important today. And they should serve to calm down the craze among those fanatics attempting to unleash a new world war," he said.

Yuri Efimenko's late father, Lieutenant Colonel Efimenko, participated in the Khabarovsk Trial as an interpreter. But Yuri Efimenko only began his extensive studies about the trial in the 1990s, and has traveled to China's Harbin to visit the exhibition hall on Unit 731's crimes.

Recalling his trip to the Unit 731 museum, Efimenko said Japan's wartime bacteriological weapons program was not limited to Unit 731 as the court indictment of the Khabarovsk Trial in 1949 also mentioned another similar unit of the Japanese Kwantung Army, namely the Unit 100, which researched and manufactured bacteria for military use under the disguise of military horse epidemic prevention.

"The museum of Unit 731 in Harbin left the deepest impression on me. Everyone should visit there. I visited the site of Unit 731's camp, and my father also went. For me, those stones spoke volumes, including the relics of a crematorium and the remains of an inner prison, where the most horrific things happened. Of course, those things also took place in the laboratory building. One figure should suffice to expose their crimes: they produced five million bacilli for every person on the planet. How many people they cruelly killed and injured in China!" said the expert.

A civil group in Japan held a study session on Saturday to tell the historical truth about the Nanjing Massacre and called on the Japanese government and society to reflect on history and avoid repeating the tragedy of war of aggression.

Saturday marks China's 12th National Memorial Day for the Victims of the Nanjing Massacre which took place when Japanese troops occupied the then-Chinese capital on Dec 13, 1937, killing approximately 300,000 Chinese civilians and unarmed soldiers in one of the most barbaric episodes of WWII over the course of six weeks.

"Japan's army committed a brutal atrocity -- the Nanjing Massacre 88 years ago in 1937. Today, on this important day, let us observe a moment of silence for 30 seconds for the victims," said an organizer of the study session.

This study session was led by Jomaru Yoichi, a former journalist with the Asahi Shimbun, a Japanese daily newspaper. Yoichi compiled numerous articles published in Japanese newspapers after the Nanjing Massacre. Among them, an article published on December 24, 1937 detailed the atrocities committed by the invading Japanese army in China.

"Around 08:00, about 400-500 defeated Chinese soldiers fled. The Japanese soldiers drove them into houses and bamboo groves, setting fires on all sides. Many of them were driven out by thick smokes. The Japanese soldiers killed them one by one with rifles and bayonets. The Japanese soldiers lost track of how many they had stabbed and killed all of them by 16:00," Yoichi recounted.

Many Japanese citizens said the Japanese government and society must confront the truth of history, and it's important to disseminate accurate historical information in contemporary Japan.

"The Nanjing Massacre is a real incident. The remarks that 'The Nanjing Massacre didn't exist' or 'The Japanese army was powerful and righteous' ignore historical evidence and deny the facts outright. I believe these are all attempts to hide the truth of history. I think these are all wrong. Facts are facts, and we must face history squarely," said a participant at the study session.

"I used to teach history in high school. In 1988, I spent two weeks in China and visited for the first time the site documenting the war crimes of the invading Japanese army. On the 80th anniversary of the end of World War II, the social atmosphere in Japan is gradually becoming strange. We must seriously examine Japan's past history, and disseminating accurate history has become even more important," said another participant.

Some expressed their concern that the Japanese government's historical revisionism, its attempt to cover up the truth of history, and its path towards military expansion will prevent Japan from facing the future.

"The fact that the Japanese army's war of aggression is not taught in social studies or history courses. I have no choice but to learn this myself even now at my age. The idea of upholding the pacifist constitution is becoming increasingly strong. Current Japanese politicians are pursuing a military expansion strategy, which I find incomprehensible," said another participant.

In 2014, China's top legislature designated December 13 as a national memorial day for the massacre victims.
