Traveling is often about seeking beauty, breathtaking landscapes, and exotic cuisine. But on some journeys, the destination calls us to face the darkest side of humanity. That is exactly what I felt when I landed in Harbin, in the far northeast of China. Known today for its world-famous ice festival and Russian-influenced architecture, the city hides a horrific past beneath its snow: Unit 731.
If you are a history buff, a Second World War enthusiast, or a follower of “dark tourism,” you need to know about this place. In this article, I will recount my experience visiting the Museum of Evidence of War Crimes by the Japanese Army’s Unit 731 and explain why this episode is considered by many historians to be even more brutal than the Nazi experiments.
Or watch my full experience on Youtube:
What Was Unit 731?
Before diving into the details of the visit, we need to understand the context. Between 1937 and 1945, during the Japanese occupation of Manchuria, Japan established a secret biological and chemical warfare research complex in Harbin. Under the command of General Shiro Ishii, Unit 731 conducted lethal experiments on living human beings.
The victims were mostly Chinese, but they also included Russians, Koreans, and other prisoners of war. The Japanese referred to them as “maruta” (logs), a dehumanizing term indicating that these people were no longer considered human, but merely laboratory supplies.
The Experience of Visiting the Museum in Harbin
Getting to the museum is easy, but the atmosphere surrounding it is heavy. Located in the Pingfang district, the site is now a silent memorial. Right at the entrance, it is common to see Chinese military officials on official visits. For the Chinese people, this wound is still very much open, and the government makes a point of preserving this memory so the world never forgets.
The museum is divided into a modern section, featuring multimedia exhibitions and documents, and an outdoor area where the original ruins of the complex remain—such as bunkers, bacterial labs, and the incineration towers.
Experiments That Defy the Imagination
As you walk through the corridors, the reconstructions and documents reveal stomach-turning details. Here are some of the points that struck me most during the visit:
- Biological Warfare and Plagues: They intentionally tested diseases such as anthrax, bubonic plague, cholera, and typhoid fever on prisoners to observe the effectiveness of biological bombs.
- Extreme Freezing Tests: Since Harbin is one of the coldest cities in China (reaching -30°C), Unit 731 used the climate to its advantage. They left prisoners outside until their limbs froze solid. Then, they tested defrosting methods, which frequently resulted in gangrene and brutal amputations without anesthesia.
- Vivisections Without Anesthesia: Yes, you read that correctly. Doctors dissected living people to study organ function in real-time, arguing that anesthesia would alter the research results.
- Vacuum and Pressure Chambers: Prisoners were placed in chambers where the pressure was increased or decreased until their eyes or internal organs literally exploded.
The Fate of the Criminals: A Historical Injustice
One of the most revolting parts of the Unit 731 story is what happened after the war ended. Unlike the Nazi doctors tried at Nuremberg, many leaders of Unit 731 were never punished.
When the United States occupied Japan, they struck a secret deal: in exchange for the biological and chemical research data collected by the unit, the Japanese officials would receive immunity. Many of them returned to civilian life in Japan and became renowned doctors, university professors, and even founders of pharmaceutical companies. It is a stain on the history of international justice that the museum emphasizes.
Tips for Those Wishing to Visit Harbin
If you decide to take this historical trip, here are some practical tips to make your journey easier:
- How to Get There: The museum is a bit far from central Harbin, but you can easily reach it using Metro Line 1. The final station drops you about a 10-minute walk from the museum.
- Entrance and Documentation: Entry is free, but you must have your passport to enter. Security in China is strict at historical sites.
- Prepare Emotionally: This is not a light visit. Set aside at least 3 hours to walk through everything calmly and process the information. The museum offers audio guides in several languages, including English.
- Use Translation Apps: Many signs in the outdoor area (bunker ruins) are only in Chinese. Have an app like Google Translate with the offline Chinese pack downloaded to translate via camera.
- When to Go: Harbin is famous for the Ice Festival in January, but prepare for extreme cold. If you want to visit the museum with more thermal comfort, choose spring or autumn.
Why Visit Places Like This?
Many ask me why visit a place of such suffering. The answer is simple: awareness. Visiting Unit 731 in Harbin is an act of respect for the victims and a way to ensure that history is not buried. In a world where geopolitical tensions are still latent, understanding the extremes of human cruelty helps us value peace and human rights.
Harbin is a fascinating city, full of contrasts and a very rich history. But it is only fully understood when we face what happened in the Pingfang district.
