Nam Koo Terrace — the haunted wartime mansion of Wan Chai, Hong Kong

Nam Koo Terrace is a Grade I historic building in the Wan Chai district of Hong Kong that has been called the 'most haunted house in Hong Kong.' The two-story Chinese Renaissance-style mansion was built around 1915 and has stood largely vacant for decades. During the Japanese occupation of Hong Kong (1941-1945), the building was allegedly used as a 'comfort station' — a facility where women were forced into sexual slavery by the Japanese military. The suffering endured within the building's walls is believed to be the source of its intense haunting. Visitors and neighbouring residents have reported seeing female ghosts in the windows, hearing screaming and crying at night, and experiencing overwhelming feelings of distress when near the property. In the 1960s, a group of young people who entered the building reportedly emerged in states of hysteria, some claiming to have been possessed. The incident was widely reported in Hong Kong media and cemented the building's fearsome reputation. Developers who have attempted to renovate or redevelop the property have reportedly encountered persistent construction problems and worker refusals. Nam Koo Terrace represents one of the most traumatic intersections of wartime atrocity and supernatural activity in Asia.
