Chapter 5 Chapter Two Cruel Parade

As mentioned above, in Unit 731, there are research groups on topics such as "studying pathology" (Okamoto and Ishikawa classes), "studying pharmacology" (Gaowei class), and "studying frostbite" (Yoshimura class). The problem lies in the inside story of this research group. According to the testimonies given by former military personnel, for example, one of the research topics of "Study Pharmacology" is to study the effects of various drugs (poisons) on the human body and the methods of detoxification. No matter in the past or today, the medical field only uses plants or small animals as experimental materials to study the harm of highly toxic drugs to living things.

But Unit 731 used "Marutai".Most of the "Malutai" sent to the special prison were Russians and Chinese who were arrested for the anti-Japanese war, and after interrogation and torture, they were decided to be shot or hanged.Instead of executing the death penalty, they are forced to suffer the fate of becoming "Marutai", which is to execute the death penalty in the name of living body experiments. Readers may remember that there was a "Diyin incident" on January 26, 1948, shortly after the end of the war: 16 bank employees were at the Imperial Bank's Tsuimamachi branch at 33 Nagasaki 1-chome, Toshima District, Tokyo. A person who claimed to be "personnel from the Tokyo Metropolitan Epidemic Prevention Department" forced them to take poison, 12 of them died immediately, and 164,000 yen in cash and a check with a denomination of 17,000 yen were snatched.A survivor at the time said that the prisoner who made the incident was a "about forty-five or six-year-old, about five feet two inches tall, with a thin, bald head. As a doctor, the criminal seemed a bit rude."

This event has several characteristics: First of all, the poison used in the crime is "cyanic acid compound" (instead of potassium cyanate), and the straws used by criminals (glass medical utensils, used to accurately measure the amount of highly toxic liquids) and medicine boxes are all part of the research of the old Japanese army. Special equipment for conducting bacterial experiments. Secondly, judging from the behavior before and after the crime, the criminal seems to have a wealth of knowledge about the "cyanic acid compound" and its "antidote". Thirdly, the offender was judged to have extraordinary experience in the methods of administering poisons.

Several scholars in the past have pointed out that the so-called Institute of Parts of the Japanese Army here refers to Manchurian Unit 731. This time, the former army personnel I contacted unanimously testified: "After the Diyin incident, the criminal police came to investigate." "I was called to the police station and let me see the simulated photos", they asked me "Do you know the person named XX?" Many former army personnel were detained for a long time.Is the real culprit of the Teiyin incident the Hirasawa Sadomichi who has been moaning in prison for 33 long years after the war?Regarding this point, I have no specific materials, and I have no obligation to explain.

What I want to explain is the fact that many investigators investigated the former military personnel one by one from the poisons used in the Imperial Bank incident, the straws, the actions of the criminals, and their age and appearance.At that time, a former member of the army (a lieutenant) who was interrogated by the criminal police said that as soon as they met, the criminal police said: "Oh, it really looks like the criminal in the Diyin incident." When the members of the former army got together, they still said to this day: "The real criminal who caused the Imperial Bank incident was not Pyeongtaek. Regardless of the method or the poison used, it must be the guys from Unit 731." The fact that Shiro Ishii, the commander of the unit, served as an advisor and sometimes secretly called secret meetings will be introduced later.)

The search authorities centered on the members of the "research pharmacology" class of the former Unit 731, and investigated the former members of the unit one by one, which has a certain reason. Unit 731 used a lot of "Maruta" in order to study the cyanic acid compound used for killing and its antidote. It is not simply to study poisons and manufacture antidotes, but to confirm the effects of the manufactured poisons.Taking "Maruta" as an object, they studied in detail its minimum lethal dose and the "poisoning method" aimed at murder. Let me write a short story about the brutal experiment conducted by Unit 731 on the "Maruta" in custody!

In Unit 731, there is a person who is good at drawing Japanese paintings. He was born in Kanazawa City, Ishikawa Prefecture. He was originally an artist who drew base maps. In an era when the wartime slogan "Luxury is the enemy" prevailed, some famous women cut off the sleeves of their kimonos for dresses, and newspapers reported heavily.The number of people ordering yuzen-dyed kimonos has decreased significantly.Painters gradually lost their jobs or changed jobs because they felt that their future was hopeless. The painter asked the army to arrange a job for himself that could give full play to his painting talent.After passing the examination for military civilian staff, he was admitted and assigned to Manchuria 731 Unit.That was January 1942.When he reported to the headquarters, the people there asked after learning about his resume: "Can you make a map?"

At that time, many drawings such as maps drawn by the army and sketches of buildings were drawn with pens.However, he has been drawing Kaga Yuzen pictures, but he has never worked with a pen.The artist's skill in drawing Kaga Yuzen-bottom paintings is to use several fine brushes to draw patterns. "Although I have never used a fountain pen or quill, as long as I have a fine brush, I can always manage to trace the picture!" He replied. People in the personnel department were very interested after hearing this, saying that this is very interesting, let's draw and see!So he took out a map and put it in front of him to see if he could draw it with a fine brush.

Carefully waving a fine-brush brush on a piece of strong Japanese paper, he began to draw the map.Drawing the subtle changes of roads and rivers, marking the villages scattered among dry fields and hills, etc. is indeed a very complicated task, but it is not difficult to complete using the delicate technique of drawing Yuzen base maps.The fine-bristle tip in his hand freely traced lines and drew a map.Maps and text took about three hours.There are people in the army who specialize in compiling maps.At that time, there was a capable draftsman named T in the department of the Bingyao Geography Division.The map he drew was sent to the draftsman T of the Bingyao Geography Team.The cartographer was amazed to see the map skillfully drawn using only a fine brush and no other cartographic aids: "Well... it's the first time I've seen a map drawn with a brush, really. good!"

It is said that T took the map and showed it to others everywhere.A person with painting talent and superb skills joined Unit 731, and the news soon reached the ears of the army leaders. He gradually got used to the work of Unit 731.One day, he received a call from the leader.The content of the order is "report to Yoshimura's class with brushes and painting tools". The Yoshimura class is a research group that mainly studies frostbite.The frostbite treatment of this class is mainly carried out in winter (November-March of the following year).Winter in Harbin is very cold, and the temperature at night often drops below minus 40 degrees.At 11 or 12 o'clock in the evening, Ban Yoshimura took "Maruta" to the special disposal room and soaked their hands and feet in buckets filled with cold water to artificially create frostbite.

Take the "Maruta" whose hands and feet have been soaked in water to the outdoors and expose them to sub-zero outdoor temperatures. After a certain period of time, they will cause frostbite.They estimated that frostbite had occurred, so they brought "Maruta" back indoors for "treatment".At that time, among the soldiers of the Kwantung Army who invaded Northeast China, many suffered from frostbite due to fighting in the extremely cold region. In order to study the principle of frostbite and improve treatment methods, Unit 731 has been stepping up the collection of information on bacterial infection routes under extremely cold conditions.It was daytime when the artist reported for duty with painting tools. A few hours later, he returned to a certain class to which he belonged with a pale face and a very haggard face, with a dozen completed drawings under his armpit. painting.He sat down and opened the painting on the table.This is extremely brutal color painting.Anyone can't help but turn their head away after watching it, and can't bear to watch it. These are very cruel and repulsive pictures.No, it's not so much a painting, but a sketch drawn in ink, which is also used as a tool used in Japanese painting and painted with light colors.The painting depicts the severe frostbitten hands and feet of "Maruta". In the severe cold, as long as the hands and feet soaked in cold water are placed outside, frostbite will occur in sight.The outdoor temperature was -40°C, and the exposed skin of "Maruta" initially turned white due to anemia, and then turned from red to purple due to congestion, and blisters formed on the swollen skin, and then ruptured and festered, turning purple-black. Muscle tissue necrosis.Skin soaked in cold water exposed to extreme cold conditions will develop from mild frostbite to complete frostbite in a very short period of time. In order to confirm whether he had suffered from complete frostbite, members of Yoshimura's squad beat "Maruta"'s hands and feet with four-edged wooden sticks.If the beating continues, if there is still a "pain" feeling, then it proves that the frostbite has not been completely frostbitten.Complete frostbite is gangrenous frostbite.The affected part becomes gangrene, all muscle tissue is necrotic, and the skin turns dark black and falls off.After Yoshimura Ban confirmed that he was completely frostbitten, he brought "Maruta" into the house. At this time, treat the frostbitten "Maruta".Soak their limbs in cold water, gradually increasing the water temperature.Sometimes, they suddenly put their limbs into 15°C warm water to see how the frostbite of "Maruta" would react; How, to study the relationship between water temperature at the time of treatment and degree of frostbite.They changed the external conditions and experimented thoroughly. "The purpose of Yoshimura Ban's experiment is not to treat 'Maruta', but to collect information on how to accurately measure the temperature of the skin surface, the time required for cells to become necrotic, and the entire process. … Soaking the hands and feet of 'Maruta' in warm water is also to find the most suitable water temperature for treating frostbite and the time range for soaking in warm water.... However, once the completely frostbitten limbs of 'Maruta' are suddenly soaked in hot water, In the water, the entire muscle tissue of that part will fall off at once... the bones will be exposed, and then the limbs can only be amputated, otherwise, 'Marutai' will not be able to survive," said a former army member. It is these deformed and necrotic limbs of "Maruta" that the painter depicted. There was a picture of Maruta's hands, the flesh from the knuckles to the fingertips was completely rotting away.Another painting depicts the two feet of "Maruta", without the part below the ankle bone.In another picture, bones were exposed from the shoulders to the thighs.There are also paintings with short limbs like seals.A painting of frostbite with blisters, depicting the gradual purple-black coloration of muscle tissue.The colored paintings he drew according to the order are the records of the frostbite experiments.At that time, Ban Yoshimura took meticulous photos of the frostbite experiments using "Maruta", included them in black and white film, and also made a documentary film.However, the only shortcoming in these experimental records is "no color".At that time, no color film was developed, and there was no way to make "colored photos" of the photos taken except for coloring them afterwards.Therefore, Yoshimura Ban took a fancy to his painting talent.Using the skills and vision he had developed from drawing Yuzen dyeing base maps, he was able to complete the sketching of some parts of "Maruta" in a short period of time, and reproduced it in the album, making it a color painting.It is a substitute for color film.What used to be used to paint the beauty of yuzen dyeing, a design technique designed to adorn girls' long-sleeved kimonos, is now being used to document brutal experiments.Whether his heart is painful or not doesn't matter to Yoshimura Ban. What they need is the color painting that reproduces the rotten hands and feet of "Maruta" intact, and what they need is the painting genius who depicts those things. Since then, he has been called many times to "report with painting tools".Colleagues saw that his facial expression always changed to flustered every time he left.He became silent.Soon, it wasn't just Yoshimura Ban who paged him. He got into a situation where he had to describe the results of various bacterial experiments using "Maruta".The request made to him is partial color sketching.He really wanted to know what kind of experiment was carried out in that "part"?Is there any risk of infection when sketching at close range?But he didn't get any instructions.After he was demobilized at the end of the war, he never attended a gathering of former troops.Whenever he learned of such gatherings, he muttered: "It's superfluous...there are nasty memories left in Unit 731, and there is nothing worthy of the original unit members gathering together to remember Yes." Among the former comrades-in-arms, very few people knew where he lived. On November 4, 1982, the person in charge of the Yoshimura class, Hisato Yoshimura, gave the following answer in an interview with the Mainichi Shimbun: Question: According to reports, you have conducted experiments on living organisms with frostbite using a cryogenic device. A: There was no such device at that time.In order to implement the strategy against the Soviet Union, it was studied whether the cold-proof equipment could withstand the low temperature of minus 70°C.For this purpose, freezers are manufactured.Due to the late arrival of the equipment, trials were not started until the end of the war.However, it was blown up when the Soviet Union entered the war.I'm afraid you heard these words from the boy soldiers! Q: I heard that you conducted research on preventing frostbite by ethnicity. Answer: The method of putting the middle finger in ice water to study its response is called hunting.This is a method that is also used today.At that time, according to the investigation of the Kwantung Army, frostbite would not occur if the temperature was lower than -4°C.Therefore, we performed experiments at 0°C.Moreover, it was not carried out using "Maruta", but was carried out with the cooperation of the local people, not a live experiment.I try not to get close to the special squad that looks after "Maruta".Later, I also conducted research on the treatment of frostbite, which was conducted by my subordinate military doctor, the lieutenant.Although he made a report, I didn't ask much.What he did, I don't know. Q: Is it true that infants have been studied to prevent frostbite? Answer: In 1972, this matter became an issue at an academic conference, and the technician (who died in 1973) who conducted the research together was questioned.He wrote back saying, "Using his own baby." I still have the letter to this day.At that time, it was believed that life was as light as a feather, and it was an honor to be able to help the army.Using your own children for experiments is not a problem.Wasn't the first vaccination also carried out on his own son? Q: Why did you join Ishii's unit? Answer: My mentor at the university said: "Go to Manchuria!" I once said no.But he said, if you don't go, you will be fired. Question: Even though you did not carry out live experiments, don't you still have the responsibility of supervising your subordinates? A: Maybe there is a supervisory responsibility.However, since he has joined the army, there is nothing he can do about it. However, it was this Yoshimura who published an academic paper on his frostbite experiments.Regarding this incident, Mr. Shingo Takasugi, who traced the post-war footprints of the cadres of the 731 Unit, has detailed records in the paper "Tracking the Remaining Cadres of the Ishii Bacteria Unit".Let's quote some of the content from it. This paper was published by Yoshimura Shouto in the Japanese Physiological Society's English journal "Japanese Physiology Quarterly" after the war. It is a paper on cold physiology. Just as the aforementioned Watanabe published in the M newspaper, Yoshimura conducted freezing experiments on other ethnic groups (including Chinese, Manchurian Mongols and Oroqen people), and also conducted freezing experiments on more than 100 Japanese students traveling in Manchuria ( 18 to 28 years old) and Chinese coolies (a derogatory term for laborers) have been experimented with in vivo.In order to investigate the differences between different age groups, live experiments were also conducted on Chinese primary school students aged 7 to 14. What's even more shocking is that he also conducted in vivo experiments by soaking the middle fingers of babies on the third day, one month, and six months of age in frozen water for 30 minutes. Readers can understand at a glance that these experiments are not carried out willingly by volunteers.Babies on the third day of life are unlikely to be willing to offer their fingers for freezing experiments.What's more, parents in ordinary families would not be willing to use babies who are only three days old for freezing experiments.Soak your fingers in cold water for 30 minutes, and the baby will cry hoarsely. Due to this situation, it is only possible to specially build a facility in the secret room that can force babies to conduct experiments.Of course, this kind of experiment can only be carried out in the facilities of Unit 731. To me, this situation is very tragic, but the feelings of those Japanese scholars who accepted this kind of paper are unimaginable. In the records of the military trial in Khabarovsk, there are many witnesses who corroborate the frostbite research conducted by Yoshimura.Some of the testimonies are quoted below. First, I quote the testimony of the former Unit 731 trainee Gudu witness: Question: Have frostbite experiments been conducted in Unit 731? Answer: Yes.I have seen this experiment. Question: Which researcher was this experiment conducted under the guidance of? Answer: Researcher Yoshimura. Question: Can you tell us about the experiment of freezing in vivo. A: Every year in the coldest months of the year - November, December, January and February, in the army.The method of this experiment is as follows: Take the subjects to the extremely cold outdoors at around 11 o'clock in the evening, let them put their hands in a bucket filled with cold water, and then take them out, and let them stand for a long time with wet hands. in the cold wind.It is also done sometimes: clothed, but barefoot, and taken out of doors, and left him standing in the cold wind at the coldest part of the night. After these people were frostbitten, they were brought into the room, and they were asked to put their feet in warm water at about 5°C, and then gradually increase the water temperature.It is to use this method to study the treatment of frostbite.I did not directly see the experiment after the subject was brought into the room.When I was on the night shift, I only saw them when they were taken outside for frostbite.Let them put their hands in the water for indoor experiments, and listen to eyewitnesses. (omitted below) The following is the statement of the former Minister of Education of Unit 731, Nishi Zhongzuo: Q: What do you know about frostbite experiments conducted in the army? Answer: According to researcher Yoshimura, they were taken out of the prison under severe cold conditions, stood empty-handed, and then blown with artificial wind (electric fan), causing frostbite to their hands.Then beat the frostbitten hand repeatedly with a small stick until the sound like hitting a small board can be heard. The following is the statement of the military police in the original Unit 731: "(Previously abbreviated) When I passed the prison laboratory, I saw five Chinese people sitting on benches. Two of them had no fingers, their hands had turned black, and three of them had their bones exposed. Although there are still Fingers, but there are only bones left. According to Yoshimura, these are the results of frostbite experiments on them. (Omitted below) There is a secret underground passage in the "Kou" building of Unit 731.This underground passage is connected to Buildings 7 and 8 of the special prison where "Malutai" is detained. It starts from the northwest corner of the first floor of the "Kou" building. Go straight ahead, turn left, and walk along a road without handrails. Going down the concrete stairs is its "entrance". Go down the stairs without handrails, turn right and walk for about half a minute. There is an underground passage, and then go up the concrete stairs. The upward stairs also have no handrails.At the top of the stairs there is an iron door that opens outwards.This is the "exit" of the underground tunnel. The "exit" is a large concrete room.An oversized concentrated lighting (equivalent to today's shadowless lamps) hangs from the high ceiling.There is an iron operating table underneath. At first glance, it looks like an operating room in a university hospital, but the difference is that there is no similar medical equipment except for the iron bed (operating table). things, but just a few buckets and large glass containers for specimens filled with formalin. This is the anatomy room of Unit 731.This dissecting room only has a small window for daylighting on the wall close to the ceiling, and it is located in the nearest place to the research rooms in the "Kou" building - the subject research group. Open the door leading to the dissecting room, and on one side of the corridor are the various research rooms of the Takahashi class responsible for studying the plague.Walking along this corridor, you can come to the intersection with the central corridor that runs through the "Kou" building in a while.The intersection is steep, and the entire end is in an uphill state, as if a piece has been planed out (protruding forward like a steep wall on a mountain). This kind of corridor structure with a reverse slope is a unique design of the 731 unit, and the personnel in the unit call it "rat turning back". What is the so-called "rat turning back"?As mentioned earlier, the whole floor along the rectangular corridor on the first floor of the "Kou" building is the bacteria factory of the fourth department under the Karasawa team.The factory was near Takahashi Ban, a place where plague fleas contaminated with Yersinia pestis were bred. Breeding plague fleas requires the use of large numbers of rats.First, mice are injected with Yersinia pestis, one or two mice are immobilized in oil tanks, and then fleas are put in to suck the blood from the mice.Breed simultaneously until bones remain. The fleas suck the blood of the rats that have been infected with plague bacteria to keep the rats warm. In the dark, the fleas will desperately reproduce. There are about 4,500 of these plague flea breeding equipment in Unit 731, and within two months, they can "manufacture" tens of kilograms of plague fleas, not one thousand or ten thousand, but tens of kilograms of plague fleas. Assuming that it is 50 kilograms of fleas, according to the calculation of experts, the number will be as many as tens of millions.This is a set of equipment capable of producing large numbers of plague fleas in just over two months. After writing this, the purpose of building the "shutouhui" at the end of the corridor in front of the research rooms of the Gaoqiao class is self-evident.In the event of an accident, these research mice injected with Yersinia pestis escaped from the research room of the Gaoqiao class. Even if they passed through the corridor, they would definitely be blocked by the steep wall of the reverse slope and could not escape forward. This is where the name "Shuhuitou" comes from. Go out from the door of the dissecting room, go straight ahead, go to the intersection with the central corridor, turn left, and go to the deepest place is the Kasahara class (research virus) laboratory. It only takes a few minutes to walk there from the dissecting room time. If you turn right in the opposite direction and go up the stairs, you will come to the second floor of the "Kou" building.On the second floor, there is the Yoshimura class research room with a very powerful freezer and heat preservation room, as well as the Minato class (studying cholera), Okamoto class, and Ishikawa class (both researching pathology).There are also Jiangdao class (research on dysentery), Ota class (research on anthrax) and Utsumi class (research on serum). These research rooms on the second floor are just a few minutes' walk from the anatomy room. The dissecting room is connected to the special prison where "Maruta" is detained through a secret underground passage, and it is very close to the research rooms. The room with the iron operating table is where Unit 731 secretly performed the vivisection on "Maruta". It is said that from 1939 when Unit 731 entered the newly established military area near the bungalow until the unit collapsed in the summer of 1945, during the six-year period, hundreds of live "Marutai" were sent to the dissection room through this secret underground tunnel.After the war, during the investigation by the Allied Forces Headquarters in Japan, Okamoto, a senior team member, confessed that the number of "Maruta" dissected in 1945 was less than 1,000. The Khabarovsk Far East Military Tribunal failed to clarify the numerous vivisections performed by Unit 731 (according to some former troops, those who had just died were called "pre-combat autopsies" - legally speaking, the dead body still has body temperature, not It is considered to be a corpse, and dissecting such a corpse is not an autopsy, but a vivisection). This is due to the fact that the troops under trial carefully concealed the facts and shielded their leaders. From the records of the Khabarovsk trial, you can see everywhere the defendant's painstaking language to conceal or minimize the facts.That is to say, the defendant was sensitive to the intention of the Soviet military authorities and the sharpness of the interrogation, and then repeatedly confessed the exposed criminal behavior in the answer to the interrogation, always adopting a kind of "things that were not asked, and nothing was said." don't talk" attitude. Therefore, although the "public trial document" recorded in Khabarovsk itself is a detailed record of the Japanese Army's criminal acts of bacterial warfare, it will create such a danger that all the actions of Unit 731 will be limited to Based on the facts listed in the "public trial documents". Materials, documents, and published documents are all printed using type. From these things, readers are prone to "superstition" on type. However, in order to reveal the truth of Unit 731, only by dabbling in printed materials or copying the facts already mentioned , is not sufficient.Relying on such a little evidence will fall into a metaphysical superficial investigation.It is nothing more than the accumulation of ready-made materials.Mistakes of inheriting and expanding existing materials are also dangerous. The "Military Trial of Bacterial Warfare" written by Seizaburo Yamada and the "Living Experiments of Three Thousand People" written by Shimamura are very good as records, because although they are based on the "public trial record" of the military trial in Khabarovsk ", but also confirmed by the author's own investigation. All the classes on the second and third floors of the "Kou" building mentioned above use the dissection room located in a corner of the army. When I talked about "Maruta" earlier, I wrote: "Maruta" was "assigned according to the serial number...as the belongings of each squad of Unit 731, and became the "material" for their live experiments according to different research purposes. . Why must "Maruta" be "distributed as the property of each class"?One of the biggest reasons for this is vivisection in the dissecting room. When collecting fresh "specimens" from living people, it must be determined in advance which class "property" these specimens belong to. According to the testimonies of the former army personnel, during the actual vivisection, the right to handle the knife and conduct experiments on the body of the "Maruta" belonged to the squad that owned the "Maruta".After the dissection and experiments are completed, the internal organs of the human body are distributed according to the requirements of each research class. They informed the various research groups in advance of their plans to dissect living bodies and conduct experiments. "After the dissection, hand over the small intestine and pancreas to Class A", "Class B needs the brain", "Class C needs the heart"... and since then, appointments have been made.This is a "pre-order" of live dissected body parts. Unit 731 conducts vivisection for roughly two purposes: The first purpose is to collect specimens.When a person suffers from an infectious disease, does the heart become enlarged?Does the liver change color?How does infection change over time?When a person is alive, dissecting a living body is the most "ideal" method to find out the changes in various parts. The value of vivisection is not just to collect samples of infectious diseases, but to study the various changes in the internal organs related to "Maruta" over time after taking a drug. In order to achieve this goal, "Marutai" was "injected" with all the substances that people wanted to get the relevant results.Inject air from the vein of "Maruta", and observe what kind of process the various organs of the body go through before they are suffocated?Although the troops knew that injecting air would lead to death, they were interested in the more detailed process. They also hung the "Maruta" upside down to conduct experiments to see what changes would happen to various parts of the body after hours and minutes of death?Or put "Maruta" into a huge centrifugal separator and perform high-speed rotation experiments repeatedly until "Maruta" dies. When urine and horse blood are injected into the kidneys, what will happen to the human body?They alternated experiments with monkey blood, horse blood, and human blood.How much blood can be drawn from "Maruta"?They used needles to conduct multiple blood tests.This is an out-and-out extraction. What happens if you send a lot of smoke into your lungs?What would happen if poison gas was used instead of smoke?What changes will occur when poisonous gas or erosive gas enters the human stomach? Trying this drug, no, when using that substance... Those things that are usually considered to be evil thoughts and taboos even the thought itself, are put into practice in Unit 731 without a care.Using X-rays to irradiate for a long time to destroy the liver is also one of the contents of the in vivo experiment.It is said that it also includes some meaningless experiments that have long been recognized in the medical field. The scalpel for dissecting living bodies is mainly mastered by qualified assistants (employees) in the research class... The idea of ​​collecting specimens was proposed by the class leader.The squad leader of each class is a famous scholar or doctor at that time.Only for "Maruta" who are particularly interested, they directly do it.Usually never soil one's own hands.Let the subordinates do everything.The staff in each class did not feel any guilt about the vivisection, rather, the class was filled with an atmosphere of anticipation for what kind of specimens could be collected this time. This is the testimony of former military personnel.After general anesthesia or local anesthesia, "Marutai" has become a "best living specimen" after one hour. According to the former army personnel, in this "experiment" of dissecting living bodies, they had accepted the "commissioned research" of the Japanese professor of Harbin Medical University and Xinjing (now Changchun) University, the capital of Manchuria at that time. According to the needs of the research topic, although there are only a few times, university professors have also visited Unit 731.Every time the guards were heavily guarded, the professor's eyes were tightly blindfolded when getting out of the car, and the blindfold was removed only after entering the building. Once, the "royal family member" who was traveling to Harbin quietly came to Unit 731. According to the regulations of "no one is allowed to enter without the permission of the commander of the Eastern Army", the commander of Shiro Ishii let this "royal family member" stand at the gate. The foreigner waited for a long time, and after saying good things, he showed him around the facility.This episode is well known among those concerned. Captain Ishii Shiro (military lieutenant general) believed that dissecting a living body was an attractive "experiment" and used it as a "bait" for Japanese medical personnel who were interested in it to join the army. Many professors were both members of Unit 731 and Taught in Harbin Medical University at that time. "A professor from a famous national university performed many difficult operations in Japanese medicine after the war. It is terrible to be defeated! Hasn’t that gentleman ever failed? No, he has experienced dozens of failures in operations,... Where did he accumulate these experiences? They are all in Unit 731!” In Kansai, I met a member of the former army. He said that he had conducted many "experiments" of difficult operations on "Maruta". "Maruta" - is a person, but not a person.Because each "Malutai" has no name, only a numbered management card.When "Maruta" is "consumed", his serial number will be used on the newly "purchased" "Maruta". However, not all those who were subjected to vivisection by Unit 731 were "anti-Japanese elements."Now let us introduce an example witnessed by a member of the former army at that time! One day in 1943, they brought a Chinese teenager into the dissection room.According to the former army personnel, the young man was not "Maruta", and it is estimated that he might have been abducted from somewhere, but the details are unknown.The boy seemed to be in despair, squatting in the corner of the dissecting room.A dozen team members in white shirts stood around the dissection table, only showing their sanitized hands.One curtly ordered the boy to climb onto the dissecting table. The Chinese teenager stripped off his upper body according to the order and lay down on the dissecting table.The boy didn't know what was about to happen to him.Then take off his pants.The juvenile's genitals have not yet grown hair. Perhaps the human body in Northeast China has less hair. Judging from the condition of the genitals and its surroundings, the boy is about twelve or thirteen years old. They first put absorbent cotton soaked in chloroform (anesthetic) over the mouth and nose of the lying Chinese teenager to give general anesthesia.Then wipe the boy's body clean with alcohol. A senior employee stepped out from the members of the Tianbe class surrounding the dissecting table, approached the boy with a scalpel in his hand, and then he cut a Y shape with the scalpel along the boy's chest cavity.Then hemostat was used to stop the bleeding, and the blood flowed out continuously, revealing the white fat, and the vivisection began. "The boy was not 'Maruta'... The boy did not carry out any anti-Japanese movement. Later, I learned that the dissection was to obtain the internal organs of a healthy boy. For this reason, the boy was dissected alive... ..." Later, a member of the former Unit 731 recalled the scene of the autopsy. The intestines, pancreas, liver, kidneys, stomach, and other internal organs were sequentially taken out from the sleeping boy, measured separately, and thrown into the bucket.The internal organs placed on the scale are still wriggling, so the pointer is shaking, and it is difficult for the team members to see the scale.Then they put the offal in the bucket into a large glass container filled with formalin and put the lid on.The scalpel glistened with juvenile bodily fluids.Due to the skillful "knife handling" of the employees, the boy's upper body became almost empty in the bleeding.取出的内脏，泡在福尔马林液中，还在不断地抽动，进行着收缩运动。 “喂，还活着呢……” 不知是谁这样说道，这可以再造一个活人。取掉胃，切除肺部之后，中国少年只剩下头部，一个小小的光头。凑班的一个人把它固定在解剖台上，在耳部到鼻子之间，横切了一刀。在剥开头皮之后，开始锯头，头盖骨被错成三角形之后取了下来，露出了脑子。部队人员用手插入柔软的保护膜，像取豆腐般地把少年的脑子取了出来，又迅速地放入装有福尔马林液的容器中，解剖台上的少年只剩下四肢和一副空躯壳了。到此，解剖结束。 "Take it!" 呆在一旁的人员把装有少年内脏的容器一个个地拿走，而对这个被迫死去的少年没有一点怜悯之心。在他们看来，甚至连判刑都不需要。少年只不过是摆在恶魔餐桌上的一块肉而已。队员双手捧着玻璃容器在走廊上一走，由于摇晃，内脏在溶液里不时作响，收缩了起来。由于容器重，生怕摔倒，他们使出全身的力气，捧着它，缓慢地走着…… 将要进入青春期的这个中国少年的姓名，恐怕同无数“马鲁太”一样，至今也无人知晓，他本人也不会知道自己被活生生地解剖的理由。在被迫短短的假寐状态中，他丧失了一切： 鲜血流如注， 活体解剖躯尽空， 五脏秤上动。 1940年9月，在浙江省杭州市郊外笕桥逮捕了一名便衣队人员（中国游击队员），在蒋介石的中央航校旧址斩首后，尸体由731部队冈本班解剖。原731部队IN氏目睹了活体解剖现场。他在回忆当时情景时写下了这首短诗。
