English Version
Tokyo Metropolitan Toyama Park in Shinjuku is often mentioned in local ghost stories, especially the area around Hakone-yama, an artificial hill inside the park.
According to rumor, if you climb Hakone-yama late at night, you may hear the sound of someone crying or groaning. Other stories claim that ghostly fireballs have been seen moving through the park, or that the spirit of a man who died by suicide appears in one of the park restrooms. Some also say that photographs taken here have an unusually high chance of capturing something strange.
The area including Toyama Park, Toyama Heights, and the National Institute of Infectious Diseases was once home to Japanese Imperial Army facilities during wartime, including a military medical school.
In July 1989, during construction at what was then the National Institute of Health and is now the National Institute of Infectious Diseases, a large number of human bones were unearthed. They were reportedly less than 100 years old. Because of this discovery, some have suggested that prisoners of war may have been used in human experiments, though this remains a theory rather than a confirmed account.
The park is in the Okubo 3-chome area of Shinjuku, Tokyo. If you visit, stay in public areas, follow posted rules and hours, and do not enter restricted facilities or private property.

深夜、箱根山と呼ばれる人工の丘に上がると、人の泣き声や呻き声が聞こえる。公園内で人魂が飛んでいる。園内のトイレで自殺した男の霊が出る。カメラ撮影をすると、高い確率で心霊写真が撮れる。などの噂があります。都立戸山公園、戸山ハイツ、国立感染症研究所の一帯は、戦時中軍医学校などの日本陸軍の施設があった場所でした。1989年7月、当時の国立予防衛生研究所（現在は国立感染症研究所）の建設現場で、死後100年を経ていない大量の人骨が発掘されており、戦争捕虜を人体実験に使ったのではないかという説が唱えられています。
