Stories associated with old castle ruins sometimes overlap between descriptions of the remaining topography and hearsay about strange occurrences. This study examines the ruins of Wakakuri Castle, Uozu Castle, and Yasuda Castle in Toyama Prefecture, comparing the claims in these rumors with the cultural property records of the local governments. We separate the parts of the stories that can be verified regarding battles and ruins from those that cannot be determined from those sources.
Survey methods and evaluation criteria
The materials used were rumor pages from three locations saved on October 16, 2026, and cultural property documents from Kurobe City, Uozu City, and Toyama City. Claims quoted from the rumor texts were individually compared, and if they were found in the cultural property documents, they were considered to match only to the extent supported by those documents. Historical records and eyewitness accounts of strange occurrences were not treated as the same evidence, and the ranking is based on editorial organization that reflects the status of verification of sources, historical background, and safety information, rather than the brutality of the battle or the number of spirits.

1st Place: Wakakuri Castle Ruins | Partial Match (74 points)
The rumored details
The page for Wakakuri Castle Ruins on the National Haunted Site Map first describes the location by stating that "earthen ramparts remain in a U-shape," and then includes a ghost story about "seeing a figure in armor in the darkness." The former is a verifiable claim about the shape of the ruins, while the latter is hearsay about the content of the experience. Just because the two are on the same page does not mean that the necessary supporting evidence is the same.
Source of the rumor and date of verification
The source of the rumor is a paranormal information website separate from the city's cultural property records. While the text includes a disclaimer stating that it should be treated as a local ghost story, it should not be interpreted as independent eyewitness testimony or a report confirmed by the city.
- Nationwide Haunted Map - Wakakuri Castle Ruins(Confirmed on 2026-10-16) — The earthen embankment remains in a U-shape.
I saw a figure in armor in the darkness.
Things that could be confirmed from official and primary source materials
Cultural property records from Kurobe City describe the Wakakuri Castle ruins as a castle site called "Tachinoshiro." Regarding the earthworks, it states that they surrounded the castle on three sides—north, west, and south—in a U-shape, with the east side open. While this description provides evidence for the shape of the earthworks, it does not describe the shadows seen in the darkness or the figures of those present.
- Official facility information - Wakakuri Castle Ruins(Confirmed on 2026-10-16) — The ruins of Wakakuri Castle, also known as Tachinoshiro, are located at a key transportation point facing the old Hokuriku Highway on the left bank of the Kurobe River.
The earthen rampart is U-shaped, enclosing the area on the north, west, and south sides, with the east side open.
Points of agreement/contradictions
The assertion regarding the shape of the earthworks was deemed supportable because it corresponds to the city's explanation, which includes specific directions. On the other hand, the armored figure could not be verified because the conditions under which it was sighted could not be compared, and like the shape of the ruins, it could not be confirmed. The overall judgment is partially in agreement, but this does not mean that the existence of the supernatural phenomenon has been partially acknowledged.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| The earthen rampart remains in a U-shape. | support | The city's cultural property records explain that the earthworks surround the area on three sides—north, west, and south—in a U-shape. I can only support this claim regarding the shape, and I will distinguish it from any evidence supporting the supernatural occurrences. | Official facility information - Wakakuri Castle Ruins |
| I saw a figure in armor in the darkness. | Unconfirmed | While city documents describe the structure of the ruins, there are no records of anyone observing a figure in armor. The conditions under which the sighting occurred in the dark are also unknown, making it impossible to determine the figure's identity. | No official data available for direct comparison. |
Alternative interpretation
Shadows in dark places can appear differently depending on lighting, distance, and viewpoint. However, since we haven't confirmed any relevant eyewitness photos or locations, we cannot determine if it was the shadow of a tree, for example. We also avoided filling in the blanks in the description of the ruins.
Scope and limitations of the investigation
The cultural property documents describe the castle's structure and history, and do not represent the results of the published eyewitness accounts. The reference map also shows the location from which the rumors originated, and does not indicate the locations where the strange occurrences occurred or the viewing routes officially recognized by the city.
Verification results: Partial match
The U-shaped earthen embankment was supported because it specifically matches the city's explanation. The claim of a figure in armor remains unconfirmed because it cannot be verified with independent records. A partial agreement was used to acknowledge this difference.

2nd Place: Yasuda Castle Ruins | Unmeasurable (69 points)
The rumored details
The paranormal information page for Yasuda Castle ruins mentions rumors that "seppuku (ritual suicide) is frequent" around the castle and that "there are many wandering spirits of defeated warriors" there. In the short explanation, the frequency of past events is linked to current strange occurrences, but no evidence is provided to verify the causal relationship or the number of incidents. This article quotes only a short portion of the claims and does not accept them as historical fact.
Source of the rumor and date of verification
The source of this information is an external paranormal information website. The rumored text lacks information to verify when the event occurred, what records it is based on, and who experienced it and where, so it does not serve the same purpose as descriptions of city excavations or cultural properties.
- Nationwide Haunted Map - Yasuda Castle Ruins(Confirmed on 2026-10-16) — Seppuku (ritual suicide) was common.
There are lots of wandering spirits of defeated warriors.
Things that could be confirmed from official and primary source materials
Guides to the Yasuda Castle ruins in Toyama City describe it as a Sengoku period flatland castle located on an alluvial fan on the left bank of the Idagawa River, at the southeastern foot of the Kureha Hills. The guide also includes a description of its scale, including the moat, making it useful as a resource for learning about the castle's location and structure. However, this information is not based on investigations into ghost sightings, nor does it corroborate the frequency of events described in rumors.
- Official facility information: Yasuda Castle Ruins(Confirmed on 2026-10-16) — This is a flatland castle from the Sengoku period located on an alluvial fan on the left bank of the Idagawa River, at the southeastern foot of the Kureha Hills. Including the moat, it measures approximately 150m east-west and 240m north-south.
Points of agreement/contradictions
The explanation that the castle ruins are a flatland castle from the Sengoku period is not the same as the claim that specific activities frequently took place there. Even if we can confirm the historical context and the scale of the moat, we cannot deduce the number of spirits of fallen warriors or the causal relationship that would explain their lingering presence to the present day. I have separated the parts where the documents provide concrete details from the parts where the rumor explanation lacks specificity.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| Seppuku (ritual suicide) was common. | Unconfirmed | Even if city records describe the age and size of the castle, they don't reveal the frequency of specific incidents. Rumors lack timelines or numbers, making it impossible to verify the claims. | No official data available for direct comparison. |
| There are lots of wandering spirits of defeated warriors. | Unconfirmed | There are no independent records in this document that observe the existence or number of spirits. The presence of castle ruins from the Sengoku period cannot be used to infer the existence of current supernatural phenomena. | No official data available for direct comparison. |
Alternative interpretation
The vast landscape of the castle ruins and knowledge of past battles may influence how one perceives the place. However, this does not involve investigating the psychological causes of specific experiences, nor does it include explanations that definitively state they were imaginations or misinterpretations.
Scope and limitations of the investigation
The rumored text lacks the timeframe and number of occurrences necessary to calculate frequency, and original eyewitness accounts cannot be verified. The castle's characteristics, confirmed from official documents, are not used to fill in these gaps, and maps are treated only as a reference for location.
Verification result: Unmeasurable
While the topography and size of Hirajo Castle can be traced from the city's description, there is no evidence to corroborate the two claims cited here regarding past frequency and the number of spirits. Therefore, we have not attempted to infer any supernatural occurrences from the castle's history, and have deemed the determination immeasurable.

Safety information and maps
Please do not cross or climb over the moats or uneven terrain of the well-maintained castle ruins for the purpose of exploration. Prioritize the preservation of cultural properties and the use of the facilities, and do not enter museums after closing hours or areas where entry is prohibited.

3rd Place: Uozu Castle Ruins | Unmeasurable (60 points)
The rumored details
The rumors page about the Uozu Castle ruins mentions that "the ghost of a samurai appears," and also describes an experience where "the steering wheel became unresponsive" when driving through the area. Because it is placed after a description of the battle, it may appear to be a continuous cause-and-effect relationship, but historical accounts and modern sightings or mechanical malfunctions must be examined separately. The number of people involved in the incident and specific descriptions of damage will not be repeated in this article.
Source of the rumor and date of verification
The claims quoted are from external paranormal information websites and are not based on investigation reports by park or road administrators. Regarding the car malfunction, we have not verified it with maintenance records or the driver's original testimony; it is treated as hearsay.
- Nationwide Haunted Map - Uozu Castle Ruins(Confirmed on 2026-10-16) — Paranormal phenomena rumored to occur at Uozu Castle ruins
The spirit of a samurai appears.
The steering wheel stopped working.
Things that could be confirmed from official and primary source materials
According to the cultural property information provided by Uozu City, the Matsukura Castle Group is described as having Matsukura Castle at its center, with subsidiary castles and forts arranged around it, and other castles such as Uozu Castle and Tenjin-yama Castle scattered over a wider area. This document provides clues to understanding the extent of the castles in the region. However, it is not used as a source to verify the troop strength, duration, and damage described on the "rumors" page, nor to verify the malfunction of a modern car.
- Official facility information - Uozu Castle Ruins(Confirmed on 2026-10-16) — The Matsukura Castle Group refers to a large-scale castle complex centered around Matsukura Castle, with subsidiary castles and forts such as Masukata Castle and Kitayama Castle located within a radius of 2-3 km, and further within a radius of 7-8 km, castles such as Uozu Castle and Tenjinyama Castle are scattered throughout.
Points of agreement/contradictions
The fact that Uozu Castle is mentioned in city records confirms its historical significance as a local castle. However, this does not support the claims regarding the spirits of samurai and the operation of chariots. I made a distinction to avoid jumping from the general understanding of a history of battles to the cause of modern experiences.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| The spirit of a samurai appears. | Unconfirmed | City records describe the layout of castles in the area, but they do not document the appearance of samurai spirits in modern times. It is important to distinguish between history and the cause of the sighting. | No official data available for direct comparison. |
| The steering wheel stopped working. | Unconfirmed | Because we haven't compared the vehicle's maintenance records or the conditions under which the issue occurred, we cannot determine the nature of the user experience or its cause. The castle's history also does not provide any supporting evidence for the mechanical cause. | No official data available for direct comparison. |
Alternative interpretation
When someone reports experiencing abnormalities in their car's operation, there are several factors that need to be checked, such as the vehicle, the road conditions, and the driving situation. Without maintenance records or on-site information, the cause cannot be determined, and it cannot be definitively stated whether it was due to a supernatural phenomenon or a normal malfunction.
Scope and limitations of the investigation
The city's webpage referenced is a document introducing the castle complex and does not verify the entire rumored historical narrative. The map is a reference location provided by the source and does not guarantee that the former castle grounds, modern experience points, and entrances to the site will coincide.
Verification result: Unmeasurable
The fact that Uozu Castle is located in the region is separate from the accuracy of the two modern experiences. Since there are no observational or maintenance records in this document to support or refute the claims, the ghost sightings and the car phenomenon were deemed unmeasurable.
Document Quality Score
| Source transparency | 22/30 | While it's possible to distinguish between the city's cultural property documents and external sources spreading rumors, the scope of claims they address differs. |

| Newness of information | 8/15 | The date of preservation, October 16, 2026, and the time of the battle or the occurrence of the modern-day experience will be treated as separate pieces of information. |

Safety information and maps
Please do not enter currently used properties such as schools or residences without permission, even if it is because of castle ruins or ghost stories. Please also avoid testing rumors while driving, and prioritize not blocking roads with photography or parking illegally on the road.

What I learned by crossing locations
The Wakakuri Castle ruins were an example where the shape of the earthworks mentioned in the rumors could be compared with the description from Kurobe City. However, the presence of the earthworks does not determine the true nature of the sounds and shadows spoken of there. The city's document used for the Uozu Castle ruins introduces the surrounding group of castles. The troop strength and duration of the siege mentioned on the rumors page cannot be treated as if they were confirmed from that document. While there is a document from the city introducing the excavation and maintenance of the Yasuda Castle ruins, it does not support the explanation that spirits haunt the area. Even though they all share the commonality of being castles, the information that can be confirmed differs from location to location.
summary
The only direct comparison we were able to make was regarding a portion of the shape of the earthworks at the Wakakuri Castle ruins. This means that the descriptions of the remains matched, but it does not prove that there were any strange occurrences. The claims regarding the strange occurrences at the Uozu Castle and Yasuda Castle ruins could not be supported or refuted using only the official documents we used. Separating the study of the history of battles and the structure of castles from determining the cause of modern personal accounts helps to avoid making definitive statements beyond the available information.
FAQ
If there was a partial match, was it considered a paranormal phenomenon?
That's incorrect. At the Wakakuri Castle ruins, the explanation of the earthwork's shape matched the city's cultural property records. This doesn't mean that the claims regarding sound and shadow were also substantiated. Please check the results for each claim.
If there is a history of battles, are stories of defeated warriors also factual?
Documents describing battles and castle ruins are different from documents verifying later eyewitness accounts. The existence of the former cannot be used to deduce the cause of the latter, and the number of people and events at the time must be verified from each source.
Is it okay to explore the castle ruins at night using a map?
The map is for reference purposes only and does not permit entry or nighttime use. In areas near cultural properties, schools, or residences, please respect the designated public areas and follow the instructions of the administrators, and do not climb on the terrain or move objects.
