Old Fukiage Tunnel is one of Tokyo’s most notorious abandoned tunnels, long associated with sightings of a female apparition in white said to appear near the entrance or within the dark interior after nightfall. The tunnel’s reputation intensified after multiple reports from explorers describing disembodied voices, footsteps, and figures standing just beyond flashlight range, often vanishing when approached. Japanese paranormal blogs and urban legend forums frequently connect the haunting to fatal accidents and suicides on the surrounding mountain road, giving rise to stories that spirits linger in the sealed, older passage even after the newer tunnel diverted traffic. Its remote forest setting and restricted access have made it a recurring location for late-night ghost investigations and kaidan-style exploration videos.
