Correction: This article previously placed “Akame Tunnel” a few kilometers outside Masuda, Shimane, on the route to Izumo Taisha Shrine. That geography doesn’t hold up — Izumo Taisha is roughly 130 km and over an hour and a half’s drive from Masuda, not a short trip down the road. We also couldn’t confirm “Akame Tunnel” as a distinct, independently documented site. What we could confirm is a real, well-documented tunnel in the same city with its own legend, which we’re covering here instead.
The Tunnel That’s Actually Documented: Ningyo Tunnel
In Iura-cho, part of Masuda City, a short tunnel along Route 191 is known locally as Ningyo Tunnel — literally “Doll Tunnel.” The story attached to it is specific and consistently repeated: if you place a doll in the tunnel’s forgotten-items box around 6 p.m., the ghost of an old woman is said to appear. Visitors describe hearing sounds or voices inside the tunnel with no one visible, particularly in the evening and after dark — reports concentrated enough around the 6 p.m. hour that locals treat the timing as part of the legend itself, not incidental.
Where the Mother-and-Daughter Story Came From
The earlier version of this page told a different, gentler story: a mother and daughter making a shrine pilgrimage in the early 1800s, trapped by a rockslide, the mother dying while her daughter went for help and couldn’t return in time. We could not find that story repeated anywhere outside this site, and given that we also couldn’t verify “Akame Tunnel” as a real, separately named location, we think it’s more honest to flag this version as unconfirmed rather than keep presenting it as this area’s defining legend. We haven’t deleted the possibility it’s a genuine local tale we simply couldn’t locate independently — but we can’t stand behind it the way we can behind Ningyo Tunnel’s documented reputation.
Can You Visit?
Ningyo Tunnel remains open to traffic on Route 191 and is a known, if minor, local landmark. As with any short road tunnel, ordinary driving caution applies, and the doll-box ritual is something visitors do at their own discretion — it isn’t an official or maintained memorial practice.
Frequently Asked Questions
Is Akame Tunnel a real, separate site from Ningyo Tunnel?
We couldn’t independently verify it as a distinct location. The tunnel we could confirm in the Masuda area, with its own documented local legend, is Ningyo Tunnel in Iura-cho.
What’s the doll ritual about?
Local accounts say leaving a doll in the tunnel’s forgotten-items box around 6 p.m. is said to summon the ghost of an old woman — a specific, consistently repeated detail rather than a vague haunting.
