Completed in 1905 as Japan’s first all-stone tunnel, the Old Amagi Tunnel is a National Important Cultural Property that carries a heavy reputation for paranormal activity tied to its dark, moss-covered interior. Many local legends originate from the perilous mountain path that preceded the tunnel, where travelers frequently perished from exhaustion or accidental falls before the stone passage offered a safer, yet eerily silent, alternative. Visitors and thrill-seekers often report hearing disembodied voices and footsteps echoing off the 35,000 stone blocks, while some claim to see the apparition of a “woman in white” or a young girl wandering the 445-meter stretch. Despite its chilling atmosphere and lack of modern lighting, the tunnel remains open to pedestrians and brave drivers in 2026, serving as both a historic landmark for literary fans and a premier destination for Japanese ghost hunters.
