[2026 Latest] Four Old Tunnels in Northern Kanto | Ghost Rumors Read from Official Documents
This article compares rumored old tunnels and railway relics in northern Kanto not based on the intensity of paranormal activity, but on their history, structure, and current usage conditions as confirmed by official documents.
Official documents only provide information on location, history, and conditions for public access and use. The existence of paranormal phenomena cannot be confirmed. This is not a ranking recommending on-site visits, but rather a comparison to help safely interpret rumors.
Method of comparing the four locations
Dark mine entrances and echoing sounds can create anxiety, but psychological impressions are different from proof of paranormal activity. Do not confuse publicly accessible areas with restricted areas.
- Primary sources: Prioritize information from local governments, administrators, and official tourism sources.
- Rumors: Clearly state that this is unconfirmed information and do not fabricate accidents, deaths, or personal accounts.
- Safety: Prioritize public access conditions, entry restrictions, weather, and traffic over fear.

How to handle online rumors
Regarding the Suhana Tunnel (formerly the Suhana Tunnel), there are posts on the internet that vividly describe its "entrance, darkness, and reverberation." However, these are merely hearsay and impressions from the posters, and the Japan Society of Civil Engineers has introduced the three tunnels, each with a different structure, as a recommended civil engineering heritage site. The first unlined tunnel was completed in 1889, and the second brick tunnel in 1917. There is no evidence from official documents or independent records to confirm these rumors as paranormal phenomena.

Editor's thoughts
At the Suhana Tunnel, the combination of the tunnel entrance, darkness, and reverberation can easily lead to unsettling perceptions of changes in sound and visibility. Official documents alone cannot determine current access status. Please prioritize the latest information from local authorities and road administrators, without entering private property or closed areas, and without obstructing road traffic. While we can describe the atmosphere of the site, the editorial team has decided not to equate psychological impressions with actual accidents, deaths, or supernatural occurrences.

What we can learn from the comparison
All four locations are real, and their locations and histories can be confirmed through documents from local governments and other sources. However, the volume of official records does not equate to the existence of paranormal phenomena. Locations with more extensive documentation were given higher scores simply because they are easier for readers to verify themselves, and do not indicate the level of danger or the strength of the spirits present.
FAQ
If there's no mention of paranormal activity in official documents, does that mean the rumors are false?
It is impossible to definitively declare something as false or definitively declare it as fact. In this article, any parts that cannot be verified will be left as "unconfirmed" or "unverifiable."
Can we verify this if we go at night?
No. Nighttime visits increase real dangers such as poor visibility, falls, traffic, the sea, rivers, cliffs, and trespassing on private property. Please do not visit under the pretext of verifying ghost stories.
Can you decide whether to visit based solely on the information provided?
No, it's not possible. Business hours, access, and conditions may change, so please check the official websites and on-site signs on the day of your visit.
Summary | Do not mix facts, rumors, and safety information.
Knowing the history of a place is not the same as certifying paranormal phenomena as fact. Limiting what can be verified through primary sources and enjoying unconfirmed rumors as they are protects cultural properties, local communities, and the readers themselves.
