Toyama Park
A Tokyo park built over a military medical school where Unit 731 research may have taken place — joggers report unease, figures in laboratory coats, and excavated bones confirm the dark past.
History & haunting lore
Toyama Park in Shinjuku sits on the former site of the Imperial Japanese Army Medical School and its research facilities. In 1989, construction workers discovered hundreds of human remains, believed to be connected to wartime medical experiments. The park's history intersects with allegations about Unit 731.
Joggers and local residents report an oppressive atmosphere in certain sections, figures in white laboratory coats who vanish when approached, and sudden feelings of dread particularly after dark. The discovery of bones confirmed that the site's dark reputation had a factual foundation.
Toyama Park is a public park in central Tokyo, open around the clock. It contains sports facilities, a garden, and walking paths. The park is surrounded by residential buildings and is served by nearby train stations. Visit in daylight for context — the atmosphere shifts noticeably after dark.
