The shadows of samurai at Oguchi Castle Ruins Park, the mist at Fukiage Park, and photographs of Ansho Castle Ruins Park. Comparing the articles about parks in Aichi Prefecture with local government documents reveals discrepancies between the verifiable history of prisons and the unsubstantiated stories of execution grounds. There are also inconsistencies in the addresses of the castle ruins, indicating a gap between finding the facilities and identifying the rumored locations.
Survey methods and evaluation criteria
On October 20, 2026, we compared each page of the National Haunted Map, saved on that date, with the data for Nagoya City, Anjo City, and Oguchi Town. The judgments were categorized into five groups: match, partial match, mismatch, immeasurable, and new fact, representing the comparison results for individual histories and eyewitness claims. The rankings and scores out of 100 indicate the quality of the data, based on source transparency (30 points), historical/spatial context (25 points), safety information (20 points), recency of information (15 points), and source transparency of rumors (10 points). These scores do not represent the likelihood of fear or the actual existence of paranormal phenomena.
| Rank | point | The main points of the rumor | judgement | Document quality |
|---|---|---|---|---|
| 1 | Koguchi Castle Ruins Park | The page for Oguchi Castle Ruins Park on the National Haunted Site Map links the battle in late June 1561, the death of Iwamuro Nagato-no-kami, and Nobunaga's retreat. It then states, "A shadow like a samurai crossed the path..." | unmeasurable | 83/100 |
| 2 | Fukiage Park | Regarding Fukiage Park, the National Haunted Map states, "There was once a prison and execution ground here." It also mentions the site of the Chausuyama Kofun (ancient burial mound), saying, "Late at night, a mist can be seen..." | Partial match | 81/100 |
| 3 | Ansho Castle Ruins Park | The entry for Anshojo Castle Ruins Park in the nationwide paranormal map mentions that the atmosphere changes if you proceed into the forest from "the white bridge-like structure on the road side." The stone seen there was described as "a stone that looks like a grave..." | unmeasurable | 69/100 |
1st place: Oguchi Castle Ruins Park | Unmeasurable (83 points)

The rumored details
The page for Oguchi Castle Ruins Park on the National Haunted Map links the battle in late June 1561, where Iwamuro Nagato-no-kami was killed, to Nobunaga's retreat. It then states that "a shadow resembling a samurai has crossed the path" and "orbs have appeared in photographs." We will compare the details of the battle with the anecdotal accounts about the shadows and photographs separately.
Source of the rumor and date of verification
This is a secondary listing on the National Haunted People Map. The reference materials for the battle description, as well as the date, time, and recorder of the shadow sighting, cannot be confirmed from the text. Furthermore, the original photographs and conditions for their use are not available, so this page is not considered a primary record of the sighting.
- National Haunted Map - Oguchi Castle Ruins Park(Confirmed on 2026-10-21) — A samurai-like shadow crosses the view.
Apparently, orbs sometimes appear in photos taken around here.
Things that could be confirmed from official and primary source materials
Oguchi Town provides information about the exhibition room and watchtower at Oguchi Castle Ruins Park, listing its location as 261, Shiroyashiki 1-chome. The exhibition room and watchtower are open on Saturdays, Sundays, and public holidays, with special closures from December 29th to January 3rd. Opening hours are from 9:00 to 12:00 and 13:00 to 16:30, with last entry at 16:00. The town's description mentions a 17-meter watchtower, gate, and bridge as park facilities, and does not mention them as castle structures that remain intact from the Middle Ages.
- Oguchi Town, Oguchi Castle Ruins Park(Confirmed on 2026-10-21) — Open only on Saturdays, Sundays, and public holidays. *Closed from December 29th to January 3rd.
261, 1-chome, Shiroyashiki, Oguchi-cho, Niwa-gun, Aichi Prefecture
Points of agreement/contradictions
The town guide is a resource for checking exhibits and facilities at the castle ruins, but it cannot be used as evidence to individually confirm the battle in late June 1561 and the death of Iwamuro Nagato-no-kami as mentioned in the text. Also, the address on the rumor page is 1-262 Shiroyashiki, which is different from town address 261. Even if the park name is the same, the difference in addresses and the identity of the rumored location remain unresolved.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| A shadow like that of a samurai crossed my path. | Unconfirmed | While the hearsay in the published article can be confirmed, there is no record of the date and time of the sighting, and the town's facility guide is not evidence to support the claim of the shadow. | National Haunted Map - Oguchi Castle Ruins Park |
| Apparently, orbs can appear in the photos. | Unconfirmed | Since we do not have the original photograph or the shooting conditions, we cannot verify the presence or absence of the light image and its cause. | National Haunted Map - Oguchi Castle Ruins Park |
Alternative interpretation
Regarding the light captured in the photograph, images taken under different lighting conditions could be used for comparison, but the original image and lighting conditions are unknown. As for the shadow that resembled a samurai, the observation direction and time were not recorded, so it cannot be determined that it was caused by light or vegetation.
Scope and limitations of the investigation
This report covers the town's park guide, the rumored text, and a map with names. Historical documents verifying the date and individuals of the battle, diagrams showing the layout and entrances, and original photographs are not available. Even if the location of the facilities can be confirmed, this does not mean that the location of the battle within the castle or the sighting of shadows has been identified.
Verification result: Unmeasurable
The shadows of the samurai and the light in the photographs, which were used as the core comparison, lack original records of observation or photography. Details of the battle cannot be confirmed from the town's facility guide, and therefore, they are not categorized as either matching or not matching. The mere existence of castle ruins or exhibition rooms does not constitute a partial match.

Safety information and maps
The opening hours for the exhibition hall and observation tower do not indicate the closing times for all park paths, nor do they permit nighttime entry. The town prohibits ball games and fireworks in the park. Please check the latest management guidelines and on-site signs.

2nd Place: Fukiage Park | Partial Match (81 points)

The rumored details
The National Haunted Park map states that "there was once a prison and an execution ground here." It also mentions the site of the Chausuyama burial mound, listing the story of "a mist appearing late at night" alongside rumors of ghosts. The location of the prison, the existence of an execution ground, the current state of the burial mound, and the sighting of the mist are all separate claims that require evidence.
Source of the rumor and date of verification
The source referenced is a secondary publication from the National Haunted Map. The stories of mist and ghosts in the text lack the date and time of sighting and the first person to record them, and the classification as a male ghost and the voting do not serve as a substitute for the original record. The route through which it was first published is unknown.
- National Haunted Map - Fukiage Park(Verification date 2026-10-21) — This was once the site of a prison and execution ground.
Late at night, you can see the mist.
Things that could be confirmed from official and primary source materials
The Tsurumai Park/Kofun Course in Nagoya City explains that the Nagoya Prison was formerly located in Fukiage Park, and after it relocated to Miyoshi-cho in 1962, the park opened in 1969. It also notes that the Chausuyama Kofun and Tarozuka Kofun were located before the prison, but there are no traces of them now. This explanation from the city confirms the history and the current state of the kofun, but it is not a document that records whether or not there was an execution ground.
- Nagoya City, Showa Ward - Tsurumai Park - Ancient Burial Mound Course(Confirmed on 2026-10-21) — Previously, Nagoya Prison was located here, but when it relocated to Miyoshi Town (now Miyoshi City) in 1962, this park was opened in 1969 as an annex of Tsurumai Park.
There are no traces of it left now.
Points of agreement/contradictions
The part about the existence of a prison aligns with the city's explanation. However, the mere existence of a prison does not allow us to infer that it was also used as an execution ground. The term "burial mound site" does not necessarily mean that visible remains are still present. Since the city states that there are currently no traces, we should avoid explaining rumors based on the premise that surviving burial mounds still exist.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| Former Prison | support | The Nagoya City historical guide describes the history of the former Nagoya Prison and its subsequent relocation and opening. | Nagoya City, Showa Ward - Tsurumai Park - Ancient Burial Mound Course |
| There was an execution ground. | Unconfirmed | While it is mentioned in rumors, the city's history, as confirmed, does not contain records indicating the operation of an execution ground. | National Haunted Map - Fukiage Park |
| A mist is visible. | Unconfirmed | There are no original records of the date and time of the sighting or the conditions of observation, and the city's historical guide cannot corroborate the experience of the mist. | National Haunted Map - Fukiage Park |
Alternative interpretation
Investigating natural weather conditions related to the mist would be a useful point of comparison. However, without records of the date of observation, temperature, humidity, and lighting, it is impossible to determine whether it was a natural phenomenon or a supernatural occurrence. The facility's past use alone cannot explain the cause of the mist.
Scope and limitations of the investigation
The city's webpage we checked is a historical guide to walking trails, not a record of the prison's operations. The rumor page lists an address in Chikusa Ward, and the city's historical guide is published by Showa Ward, but the ward name of the department in charge does not prove boundaries or entrances. We have not identified any sections beyond the facility pin or sighting locations.
Verification results: Partial match
While the location of the prison mentioned in the text can be confirmed in independent city documents, the sightings of the execution ground and the mist have not been corroborated. This combination of history and the eyewitness claims has been considered to be a partial match. The existence of a prison does not constitute confirmation of the existence of the man's spirit.

Safety information and maps
The city's walking guide warns that access to the east gate of Nagoya Institute of Technology may be restricted. Do not take the listed routes as a guarantee of free passage, and do not use the university grounds as a shortcut at night. The park name maps do not lead to execution sites or burial mounds.
Map Location: This map shows the overall location of the facility, but does not determine the correspondence of addresses, sighting locations, or specific plots within the site.
3rd place: Ansho Castle Ruins Park | Unmeasurable (69 points)

The rumored details
The text for Anshojo Castle Ruins Park in the National Haunted Map mentions that the atmosphere changes when you proceed into the forest from "the white bridge-like structure on the road side." The stone seen there is vaguely referred to as "a stone that looks like a grave," and the text continues with descriptions of feeling energy and "a ghost in a photograph." Read this separately from records that confirm the identity of the stone, the location of the boundary, and the content of the photograph.
Source of the rumor and date of verification
This is a secondary listing on the National Paranormal Map, and its original publication is unknown. The text does not indicate the observation date, the original photograph, the inscription on the stone, or its location, and the classification as a female spirit is not based on the original record of the individual experience. We will retain the wording of the original publication, which does not definitively identify the stone as a grave.
- Nationwide Haunted Map - Ansho Castle Ruins Park(Confirmed on 2026-10-21) — Walking along the white bridge-like structure on the road towards the forest on the left, the atmosphere suddenly changes at a boundary, and there's a stone there that looks like a tombstone, and you can feel energy emanating from it. There's a ghost in the photo.
Things that could be confirmed from official and primary source materials
The information for Anjo Castle Ruins Park in Anjo City lists its location as 41 Shirobori, Anjo-cho, and its area as 1.18 hectares. The facilities section states that there are toilets and running water, but no multipurpose toilets or parking. The update date is June 25, 2018, and this is not a record of current on-site verification of the facilities. This facility information is not a document that explains the identity of the white bridge or stones, or what is shown in the photographs.
- Anjo City, Ansho Castle Ruins Park(Confirmed on 2026-10-21) — Location: 41 Shirobori, Anjo-cho
Area 1.18ha
Update date: June 25, 2018
Points of agreement/contradictions
The city's address is 41 Jōbori, but the rumor page, along with the name Anshō Bunka no Sato, indicates Jōbori 71. Even though the park has the same name, it's impossible to confirm which section or entrance the two addresses correspond to. The relationship between the bridge-like structure and the stones is also unclear from the facility guide, so named map pins cannot be used to prove the sighting location.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| A tomb-like stone? | Unconfirmed | The source itself uses uncertain language, and no documents indicating the location or origin of the stone have been obtained. | Nationwide Haunted Map - Ansho Castle Ruins Park |
| A ghost in the photo | Unconfirmed | We were unable to verify the original photographs and shooting conditions, and the city's facility guide does not corroborate the content of the photographs. | Nationwide Haunted Map - Ansho Castle Ruins Park |
Alternative interpretation
The way the plants are arranged, the way the paths are surrounded, and the differences in lighting can all change the atmosphere, so these are all factors to consider. However, since there are no observation conditions, we cannot say that these are the cause of the problem. Similarly, we cannot conclude that the stone is a tomb based solely on its shape, nor can we definitively say that the image in the photograph is a reflection or glare without the original.
Scope and limitations of the investigation
The city's facility information does not include the necessary materials for identifying stones and bridges on the premises. We do not have a map showing the address correspondence, records indicating the origin of the stones, original photographs, or dates, and the location of the boundaries in the published text is also unclear. Furthermore, the outdated facility information does not guarantee the current conditions of use.
Verification result: Unmeasurable
The claims regarding the photograph and the stone lack original images and identification materials, making it impossible to verify or refute them. While the difference in addresses is noted, the reason for this difference has not been determined, and therefore it is not linked to an error in the eyewitness account. We have also avoided concluding that the matching park facility information alone constitutes a partial match.

Safety information and maps
As the city's information indicates there is no parking available, please do not park on the street or in nearby facilities without permission. Do not trespass into the forest or around the stones based on rumors; please follow the designated trails and on-site signs. Please check the latest information regarding facilities and usage conditions before visiting.

What I learned by crossing locations
City documents confirmed that there was a prison in Fukiage Park. However, the same documents do not indicate whether there was an execution ground, and it is necessary to distinguish between existing remains and past locations of burial mounds. The date of the battle and the final moments of the people at Oguchi Castle Ruins Park could not be confirmed from the town's facility guide, and the stones at Ansho Castle Ruins Park have not been identified as tombs. The differences between addresses 261 and 262 in Oguchi, and 41 and 71 in Ansho cannot be resolved by a map with names alone.
summary
While some historical records can be verified through documents, original records are lacking for details of the battle, photographs, and eyewitness accounts of the mist. It is also unclear whether the difference in addresses indicates a different entrance or is a typographical error. The next step in our search for documents will require records that can directly verify the remaining questions, such as site division records for the castle ruins, operational records of the prison, and original photographs. The location of the park shown on the map does not allow us to deduce the location of the rumor or whether nighttime passage permits are in place.
FAQ
If the prison's history matches, have you also confirmed the ghost stories?
No. The partial agreement is a result of the claim that there was a prison. The presence or absence of an execution site and the stories of the mist and the man's figure are treated separately and are not presented as being corroborated by the same historical sources.
Is the reason the address is different because there are multiple entrances to the park?
The reason, including that possibility, remains unconfirmed. Since the parcels 41 and 71 in Ansho and parcels 261 and 262 in Koguchi are not linked in the documents regarding the plots or entrances, we have not concluded that they are the same location based solely on the matching facility names.
If I go to the location on the map at night, will I be able to verify the rumors?
The map shows the facilities of the entire park and does not indicate sighting locations or access permits. The small exhibition room and observation tower have opening hours, and there are also notices regarding passage through the university gates on the walking course, including Fukiage. When visiting, please prioritize the latest information from the administrator and local regulations.
