Ochiai Bridge and Akabashi Tunnel
Katsura River, Kyoto-ken
A half an hour's walk through the steep mountain range south-west of Kiyotaki Tunnel sits Ochiai Bridge and Akabashi Tunnel. Although a popular spot for photographers to capture awe-inspiring natural scenery, Ochiai Bridge and Akabashi Tunnel have a dark reputation of suicide, natural disasters, and mysterious figure sightings.
Ochiai Bridge connects the northern part of the tunnel to the opposite valley, and the steep drop into the shallow river below is said to be a commonly-used means of committing suicide. In conjunction with flood-related deaths and mysterious disappearances of local residents, the nearby walls of Akabashi Tunnel are often dotted with posters of missing people. People have claimed to see dark figures wandering or standing either side of the tunnel's entrances which disappear when approached.
There are also rumours the area has been used for sky burials (Tibetan funeral practice in which corpses are left atop mountains for wildlife and nature to use for sustenance) despite being illegal in Japan.
