Geniuses with strange tricks, the Japanese who participated in the first and second world wars were not simply samurai heroes, fat sumo wrestlers or wandering swordsmen like in manga comics. In fact, it was the brutality of the fascist army, with guns, bombs, and blood.

1. Strange game:

Born in 1892 in Japan, Siro Isi was the fourth son of a wealthy landowner and a famous sake maker. With exceptional memory, Siro has excellent academic achievements and is considered by many to be a potential genius. Early on, Siro showed outstanding ability and height, along with his agile style, showing that he was a potential leader.

During his time in the army, Siro discovered his true passion was science, especially medicine. In 1916, he was admitted to the medical faculty of Kyoto Imperial University. In addition to researching advanced medical methods, he also began to form strange habits.

Contrary to the image of doctors wearing white coats visiting patients, Siro likes to culture many types of bacteria in the laboratory. He often harassed other students and worked at night without consulting them. Even though everyone knew about Siro's actions, he was never punished, which likely boosted his confidence and ego.

Siro gradually becomes the best at creating biological weapons. In 1927, he became a military medical officer with bold ideas, and later became the best person at the Tokyo military hospital. Siro proposed the establishment of a military unit specializing in biological weapons research and development in Japan, even sending a letter of proposal directly to high-ranking commanders. Although small, Siro's idea directly violates international laws.

In his argument, Siro emphasized that Japan had signed the Geneva contract, but he did not care about those regulations. This shows the confidence and determination of Siro, a person who does not hesitate to violate established rules.

However, because there is no official approval, there are still gaps where they can circumvent the law to develop biological weapons. Of course, Siro's proposals were rejected. After that, he participated in a business trip around research areas around the world that lasted for 2 years, from 1928.

2. Research area:

After that trip, Siro returned to Japan with discoveries and a new plan. By the time he returned in 1930, much had changed. Japan is climbing to the cusp of war. Therefore, the reputation of those willing to research and develop weapons was noticed. From here, Siro is gradually being used.

After becoming a Professor of Immunology at Tokyo Military Medical School, Siro was promoted to Major and found a powerful companion in Colonel Chikiko Kosumi. Kosumi, a scientist who fought in war, recognized Siro's potential and supported him. As a result, Siro has more opportunities to expand its chemical and biological laboratories.

Following the invasion of Manchuria in 1931 and Japan's establishment of the state of Manchukuo, they used the region's resources to advance their industrialization efforts. Siro proposed the idea of ​​establishing a research unit to test biological chemical weapons in Japan. He took this idea from Western countries, and his proposal was accepted immediately to avoid the observation of the international community.

The secret research unit was established in the Hebei warm region, about 100 km south of Hebei. This is also where a number of experiments named Unit T, the predecessor of the famous Unit 731, were developed. Records of this secret facility reflect atrocities: about 1,000 prisoners were locked in cells, tunnel construction workers and innocent people were used as experiments.

They then murdered the victims with poison when they no longer considered them valuable for research. Most of those who came here died within just a month, and it is still unclear how many victims went through these painful experiments.

In the fall of 1934, one of the prisoners blew up the prison and 16 prisoners successfully escaped. However, despite being exposed, the brutal activities of the experiments continued until their official closure in 1935. With the EC, everything continued on a different basis with new, even more cruel experiments.

After the previous experimental unit was closed, Siro received orders to move to Binh Phong district, about 24 km south of Harbin, to establish a new, larger-scale biological chemical laboratory facility. This unit was called EC and marked the birth of Unit 731 in 1936. Emperor Hiroto decreed the expansion of Unit 731 and merged it with the bronze troops of the Imperial Japanese Army occupied in China. This unit, officially known as the Disease Prevention and Water Purification Unit, belongs to the Bronze Army.

3. Disease:

The base of this unit was located in Pingfeng District, Harbin City, and was expanded throughout cities in China at the peak of the EC network in 1939. This experimental unit attracted more than 10,000 people, including Japanese doctors and medical professors. The Tokyo branch of unit 731 is a medical school in Saitama prefecture built on a plot of land with an area of ​​6 square kilometers.

The 731st facility has more than 150 buildings and is designed not to be easily destroyed. In a few days, this unit can produce about 30 kg of epidemic-causing bacteria. The victims became experimental subjects, called "maruta" - a term that came from a joke among the staff here. Experimental doctors not only performed surgeries on living people but also injected animal blood into living people to study infectious diseases.

The end of Unit 731 came in August 1945, when the Empire of Japan surrendered. The General received orders from Tokyo to destroy everything at unit 731. This order was transmitted to subordinates and a whole new facility was destroyed. At that time, there were still 900 people detained at the unit. All of them were murdered, with 300 gassed with poison and 600 Chinese shot. Employees of unit 731, if captured, will have to drink poison. Complex 731 was later destroyed, and according to an American scholar, more than 200,000 people died at the hands of cruel doctors here.

In addition to the Chinese victims, 1,700 Japanese soldiers were killed in Jiangxi by this biological weapon, and at least 600 people arrested by the Japanese police became victims of the experiments. The doctors and staff involved had been trying to negotiate and receive immunity since his prosecution at the Tokyo court in 1946. Siro died on October 9, 1959 of laryngeal cancer, at the age of 67.

Despite repeated denials of the existence of unit 731, in the late 1990s Japan reluctantly acknowledged it. On August 13, 2017, Japan's leading broadcaster NHK broadcast a documentary about the truth of unit 731 in Harbin, revealing the brutal crime based on the testimony of surviving witnesses and records from the Khabarov war crimes trial conducted by the Soviet Union. This film caused a lot of controversy in Japan, but the crimes committed by Unit 731 are still a controversial topic between Japan and China to this day.

4. Explore history:

In the journey to discover the history of world wars, there are names that are evocative, strange and sometimes haunting. And among those people, one prominent name cannot be ignored: Siro Isi - the person behind the establishment and operation of Unit 731, a biological weapons research and development organization of fascist Japan during World War II.

Siro Isi, who was born in 1892 in Japan, was the fourth son of a wealthy landowner and a famous Sake producer. Born into a wealthy family, Isi was educated in a superior cultural and academic environment, reflected in his excellent academic performance in medical school. Considered by many to be a genius, Isi was famous for his exceptional photographic memory and expertise in medical research.

However, what is special about Siro Isi is not simply his talent and knowledge of medicine. He gradually developed his true passion: research into biological weapons. Ever since he was a medical student, Isi has shown a particular interest and passion for new methods and technologies in the field.

After graduating and becoming a doctor, Isi did not stop at practicing conventional medicine. He began conducting strange and sometimes very dangerous experiments in his laboratory. Unlike the image of a regular doctor, wearing a white coat and treating patients, Isi becomes strange and full of mystery.

Isi's colleagues often described him as an eccentric, with strange habits and interests. He liked to cultivate various bacteria in his laboratory, and even caused dissatisfaction in the medical community by working indistinctly at night and using some materials without the consent of others.

But the most special thing about Siro Isi is not his strange habits or strange hobbies. It was his perfection in developing and running Unit 731, a brutal and terrifying organization.

Unit 731, founded by Siro Isi in the early years of World War II, was where the most disgusting experiments took place. Here, people become experimental subjects, there is no rejection and no pity. Devastating tragedies are recorded throughout history, from testing with biological weapons on living humans to the murder of thousands of prisoners and civilians. Unit 731 became a symbol of the brutality and cruelty of Japanese fascism during the war.

And Siro Isi, as a monstrous doctor, was the operator and creator of nightmares at Unit 731. He was not only a talented medical researcher, but also a cruel and merciless leader. He proved that, under the influence of ambition and pride, people can become the cruelest and most cruel people in history.
