Global Times: More than 100 skulls found in Tokyo highly likely to have originated from Unit 731, Japanese civil group reveals
05/21/2025, Beijing, China // KISS PR Brand Story PressWire //
'The likelihood of the 'Toyama human bones' originating from the notorious Unit 731 of the Japanese army during its invasion of China is very high. Only by clarifying the historical truth can the medical crimes committed by the invading Japanese army during wartime be revealed to the world,' a representative of the Japanese civil group 'Association Demanding Investigation of Human Bones Discovered from the Site of the Army Medical College' told the Global Times in an exclusive interview, when addressing the association's 36 years of research and investigation of the startling and frightening discovery in Tokyo in 1989 of more than 100 human skulls.
On July 22, 1989, a number of human bones, referred to as the 'Toyama human bones,' were discovered at a construction site for the Health and Infectious Diseases (now the National Institute of Infectious Diseases) in Toyama-cho, Shinjuku, Tokyo. Most of the bones were skulls and femurs. The construction site is located at the former site of the Japanese Army Medical School, which is believed to have housed the headquarters of Unit 731. If confirmed, it would undoubtedly serve as further evidence of Japan's war crimes during its invasion of China.
'While I cannot 'assert' it definitively, I believe there is a high possibility that the 'Toyama human bones' belong to Unit 731,' explained Kazuyuki Kawamura, a representative from the non-government organization. The association was established in 1990 and has dedicated the past 36 years to investigating the truth behind the human bones.
'We believe it is necessary to treat this issue with seriousness, to uncover the historical facts and to return the remains of those who did not voluntarily become medical specimens to their descendants,' said the representative.
According to Kawamura, the following facts have been established so far: First, the 'Toyama human bones' are part of specimens or bodies related to the Japanese Army Medical School. Second, the bones are believed to belong to individuals of Asian descent (Mongoloid). Third, the specimens collected by the Japanese Army Medical School were obtained through two main channels -the dissection of Chinese soldiers' bodies on the battlefield by the Army Medical School's pathology department, which were then brought back to Japan as war injury specimens; the other involved Epidemic Prevention and Water Supply Department of the Imperial Japanese Army, also known as Unit 731, which was established in Harbin (then known as Manchuria), Northeast China, and sent parts of bodies (mainly heads) collected locally to the Japanese Army Medical School.
'Since the 'Toyama human bones' are not war injury specimens, they are generally believed to have been brought back to Japan through the second channel,' Kawamura noted.
A report released by Japan's Ministry of Health, Labor and Welfare in 2001 concluded that the human bones belonged to specimens stored at the former Army Medical School before August 1945, which could be part of bodies collected for the purpose of creating specimens and medical education, 'which may include specimens from the remains of those who died on the battlefield,' the report stated.
'There are claims suggesting that the bodies or specimens came from overseas areas such as Unit 731, as well as denials of such claims,' the report said. Currently, the human bones are stored in a columbarium at the National Institute of Infectious Diseases in Japan. According to Kyodo News, it is estimated that the human bones belong to the remains of more than 100 individuals.
Records from Japanese Army Medical School personnel files indicate that in 1940, a significant number of non-war injury head specimens were transported from Harbin to the school. Although it cannot be directly established that these specimens are linked to the Unit 731, it is hard to imagine that any other military unit would transport such a large number of head specimens from Harbin to the Army Medical School, Kawamura stated.
'Who collected these 'bodies' and how? How were they transported from Harbin to the Army Medical School in 1940? We have requested the Japanese government to conduct further investigations into individuals associated with Unit 731.' He revealed that the association is currently engaged in lectures, gatherings and field investigations at the site, where the bones were discovered.
This year marks the 80th anniversary of the victory of the Chinese People's War of Resistance against Japanese Aggression and the World Anti-Fascist War. The association plans to hold a commemorative event on July 20 to mark the 36th anniversary of the discovery of the human bones and report the latest findings, and they will continue their thorough investigative work in the future.
When the human bones were first discovered in July 1989, Kawamura was serving as a member of the Shinjuku Ward Assembly in Tokyo. At that time, he stated it was necessary to explore the truth behind the human bones and actively encouraged researchers and citizens interested in the matter to take part in the investigation.
Given that the Japanese government has yet to reflect on its war crimes, what messages does the association hope to convey to the outside world? In response to the question from the Global Times, Kawamura stated that only by uncovering the historical truth of the human bones can the medical crimes committed by the Japanese army during wartime be exposed, and he hopes to convey the meaning of peace to the world through this process.

Why men with broken heart syndrome are more likely to die, according to experts
Get inspired by a weekly roundup on living well, made simple. Sign up for CNN's Life, But Better newsletter for information and tools designed to improve your well-being. Source: CNN A 59-year-old man arrived at the Peking University First Hospital in Beijing for a procedure when he started having severe chest pain and shortness of breath. Four months earlier, he had cancerous tumors removed from his bladder. Around his family, he tried his best to appear strong and avoided discussions of his health. Privately, his severe anxiety over the possibility of a cancer recurrence kept him awake at night. Doctors said the man was experiencing takotsubo cardiomyopathy — also known as broken heart syndrome, as documented in a 2021 case study. The rare stress-induced heart condition has been observed primarily in women, but a study published in the Journal of the American Heart Association in May found that the illness may be more deadly for the men who get it. Thought to be caused by extreme emotional or physical events — such as learning about the death of a loved one, winning the lottery or lifting a heavy sofa — takotsubo cardiomyopathy, or TC, occurs when the heart muscle is flooded with stress hormones, causing part of it to 'freeze' in place. As the heart struggles to properly pump blood, symptoms resemble those of a heart attack, including chest pain, heart palpitations and irregular heartbeat. The new study analyzed data from nearly 200,000 patients hospitalized for TC in the United States between 2016 and 2020. While women accounted for 83% of the cases, men were more than twice as likely to die from the condition — with a mortality rate of 11.2%. 'The differences between men and women are a very striking finding,' said study coauthor Dr. Mohammad Reza Movahed, a clinical professor of medicine at the University of Arizona in Tucson. 'It raises a new, interesting question that should really be studied.' Similar to differences between men's and women's cardiovascular health more generally, the discrepancies in TC death rates are not well understood, Movahed said, especially because they counter trends in other heart diseases. It's widely theorized, however, that differences in hormone levels play a role. Stressful situations trigger the adrenal glands to release our fight-or-flight hormones, called catecholamines. They are meant to increase our blood pressure and raise our heart rate, but extreme levels can temporarily 'stun' cells in the heart's tissue, leading to TC, Movahed explained. Men are thought to produce more catecholamines during stressful situations compared with women, possibly leading men to present with more severe cases of TC, he suggested. Estrogen, a sex hormone produced at higher levels in women, may also have a protective effect on the cardiovascular system, making it easier to manage an extreme influx of catecholamines and reducing the risk of severe complications from TC, said Dr. Louis Vincent, a noninvasive-cardiology research fellow at the University of Miami, who coauthored a similar, multiyear study investigating discrepancies in men and women who had TC. Vincent was not involved in the new study. Beyond biological differences, social factors may play a role as well. 'Most (physicians) know about takotsubo, but they may think of it as a disease just affecting women, so the diagnosis might be overlooked in men,' said Dr. Deepak Bhatt, a cardiologist and the director of Mount Sinai Fuster Heart Hospital who was not involved in the study. 'With misdiagnosis, care is delayed, and that can sometimes lead to worse outcomes.' Men may also seek care at a later stage of illness, believing that their symptoms are manageable or may pass, said Dr. Alejandro Lemor, an assistant professor of interventional cardiology at the University of Mississippi Medical Center who was also not involved in the study. Deadly complications from TC include blood clots, stroke, cardiac arrest and heart failure, Lemor said. If the condition is caught early, medications can reduce the risk of having these complications, restore proper heart function and allow for full recovery within weeks, he added. Movahed's team was able to factor for important variables like age, race, income, chronic lung disease, hypertension and diabetes in the findings. However, there was no patient data on other comorbid diseases, such as a history of stroke or the presence of a Covid-19 infection, Vincent said. Additionally, the new study included in-patient diagnostic data only for those hospitalized with TC, so those who received outpatient care or died later from complications outside the hospital were likely not counted in the analysis, Movahed noted. To establish a firmer explanation for the differences in mortality rates between men and women and further test treatment methods, a more detailed dataset would be needed, Vincent said. 'People should be aware in studies like this, we're presenting findings that are based on diagnostic codes, and we're not looking at patient procedures or lab results,' Vincent said. 'But it's powerful in the sense that it lets us look at large populations and look at trends. And I think that this trend of a higher mortality in men is worth taking a deeper look into.' Sudden, severe chest pain or shortness of breath should always be treated as a medical emergency, warned Bhatt, who is also a professor of cardiovascular medicine at the Icahn School of Medicine at Mount Sinai in New York City. 'It's not a time to tough it out at home or get on the internet to figure it out. … Don't try to track down your primary care provider. Call emergency services,' Bhatt said. 'Time matters. By winning those few hours, you could save yourself irreparable damage to your heart.' Symptoms following physical stressors — a common cause of TC in men — should not be ignored, Movahed said, especially preceding medical events such as asthma attacks, seizures or complications from drug use. And while TC is caused by sudden stress, Bhatt said that managing chronic stress with daily meditation or exercise can lead to better cardiovascular health overall while giving you routines to fall back on in unexpected situations.

The Genetic Mystery of Why Cats Purr May Finally Be Solved
A study from Japan has identified potential genes behind cat purrs, and the discovery could help us understand why our furry companions make these contented rumblings. Despite humanity's long relationship with domestic cats (Felis catus), the purr remains mysterious, and its purpose is still up for debate. So is whether similar vocal vibrations in big cats also count as purrs, or if the phenomenon is unique to the smaller members of the cat family. The new information may eventually help solve some of these outstanding questions. Analyzing the DNA and owner-reported behavior of 280 domestic cats, Kyoto University biologist Yume Okamoto and colleagues identified a gene linked to purring and other forms of cat vocalizations. Cats with short-type androgen receptor genes were reported to purr more by their owners than those with a long-type. Male cats with this short-type gene were also reported to be more vocal towards humans. Androgen receptors mainly regulate testosterone, so the length of the gene likely influences testosterone-related behaviors, which include vocalization. By examining this gene across 11 cat species, the researchers found the long-type version was only present in domestic cats. Even their closest relatives, the fishing cat (Prionailurus viverrinus) and leopard cat (Prionailurus bengalensis), did not have the longer forms of the gene, suggesting it arose during cat domestication. Previous research found pure-bred cats are more likely to have the long-type gene than mixed-breed cats, which often began life as strays. As such, the researchers suspect cats consistently raised by humans aren't as dependent on vocal communication for their survival, allowing cats with the long-type genetic variation to survive in the pure-bred population. "This result aligns with the association between purring and vocal communication as strategies for seeking attention or support, benefiting survival through interactions with both cats and humans," Okamoto and team write in their paper. Cats also purr when they are severely injured, so some researchers have proposed purring could be a healing mechanism too. A few years ago, researchers found squishy pads in cat vocal cords produce the low-pitched vibrations without muscle contractions, so the 25- to 30-Hz rumble is, to some extent, automated. We're gradually getting a better understanding of this soothing cat behavior. "Through our research, we hope to deepen our understanding of cats and contribute to building happier relationships between cats and humans," says Okamoto. This research was published in PLOS One.
