This study compares specific rumors about Hitotsumori Park, Senshu Park, and Omoriyama Park in Akita City, Akita Prefecture, with information from the Akita City government's official website, starting with rumors posted on paranormal information websites. The aim is not to determine the presence of ghosts, but to organize how much information about the history, structure, and usage of the locations can be confirmed from other sources.
Survey methods and evaluation criteria
The rumor posting pages were treated solely as evidence of the rumor's existence, while official and administrator pages were used to verify the facility's history, structure, and usage conditions. Claims were categorized as "supported," "unconfirmed," and "contradictory." A direct contradiction resulted in a discrepancy, a coexistence of supported and unconfirmed claims resulted in a partial agreement, all claims resulted in an agreement, a meaningful official discovery without a valid comparison resulted in a new fact, and all others were considered immeasurable. The items compared here included not only the supernatural occurrences but also the date, purpose, target, structure, and history of the legend as written in the rumor; the existence of the posting source or the location name alone were not counted as evidence of the supernatural occurrences.

1st Place: Hitotsumori Park | Unmeasurable (82 points)
The rumored details
An external rumor-sharing page describes Hitotsumori Park as a park and castle ruin in Akita City, Akita Prefecture, and states that "a female ghost appears there." Furthermore, it lists multiple posts and descriptions mentioning a closed tunnel, a cemetery on the south side of the park, ghost sightings there, and frequent presence of delinquents and police. However, the page itself cautions that the posted information may contain unfounded information, and here we will treat the content as concrete evidence of the rumor.
Source of the rumor and date of verification
The source referenced was the Mori Park page of one of the nationwide haunted maps. The page's update date is June 26, 2024, while the post itself shows an update date of January 2, 2015. Since the original source and the identity of the poster cannot be determined from the page, it will be treated as a secondary publication with an unknown origin.
- Nationwide Haunted Map: "Hitotsumori Park"(Confirmed on 2026-10-05) — Hitotsumori Park is a park and castle ruin located in Akita City, Akita Prefecture, and is considered a haunted spot. It is known as a haunted spot because there are rumors that a female ghost appears there.
Things that could be confirmed from official and primary source materials
The Akita City official website describes Hitotsumori Park as a comprehensive park for citizens to use for rest, appreciation, strolling, and recreational exercise, listing a Japanese garden, rock garden, community gymnasium, tennis courts, jogging course, and the former Kurosawa family residence. The cherry blossom plaza, azalea garden, and 90-meter promenade are also mentioned, but there is no mention of the rumored closed tunnel, cemetery, or female ghost.
- Akita City Official Website: "Overview of Hitotsumori Park"(Confirmed on 2026-10-05) — This comprehensive park is popular with citizens as it combines static recreation, such as a Japanese garden and a rock garden, with dynamic recreation, such as a community gymnasium and jogging courses.
Points of agreement/contradictions
There is no record of "a female ghost appearing" corresponding to the official summary, so we cannot support or deny the existence of a ghost. Similarly, "a closed tunnel" and "the cemetery is on the south side of the park" could not be matched as the same entity in the facility list and information on the official page. The fact that the official site provides detailed information about the park's facilities does not in itself support the claims of paranormal activity or rumors, therefore, the comparison result was deemed indeterminate.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| A female ghost appears | Unconfirmed | The source of the rumor mentions a female ghost, but the official Akita City overview is a description of the park facilities and does not provide any records that independently confirm the phenomenon. | No official data available for direct comparison. |
| Closed tunnel | Unconfirmed | The tunnel description on the rumor page does not specify an entrance or official name, and there is no record in the list of facilities in the official Akita City overview that can identify the same structure, so its existence and origin cannot be confirmed. | No official data available for direct comparison. |
| The cemetery is on the south side of the park. | Unconfirmed | The location of the cemetery on the south side is only mentioned in the rumor page, and it is not possible to verify the relationship between the cemetery's location and the rumor on a one-to-one basis with the official facility guide. | No official data available for direct comparison. |
Alternative interpretation
The rumored terms "tunnel" and "cemetery" could refer to actual terrain or past facilities, but this cannot be uniquely identified from the official summary alone. The darkness at night, the trees, and the appearance of enclosed structures may have intensified the sense of fear, and we do not equate personal experiences with factual confirmation.
Scope and limitations of the investigation
Our verification was limited to the original text of the rumor source and the official summary page of Akita City. The absence of information on the official page does not prove that the tunnel or cemetery does not exist. Furthermore, we were unable to independently verify the original posting date, location, or speaker of the rumor page posts and comments, and we did not conduct any additional searches of public records of accidents or crimes.
Verification result: Unmeasurable
Regarding the specific claims in the rumors about the female ghost, the closed tunnel, and the cemetery on the south side, we could not find any records in the official documents that directly support the same targets. However, the mere absence of information in the official summary does not necessarily mean there is a discrepancy. Therefore, we will separate the confirmed park facility information from the unverified rumors and determine at this time that the conclusion is "unmeasurable."

2nd Place: Senshu Park | New Facts (81 points)
The rumored details
The Senshu Park page on the National Haunted Map lists rumors of a female ghost appearing there, a description of it being the place where the most spirits gather in the prefecture, mentions sudden chills and nausea, and claims that the ghost of an Edo-period samurai has been sighted there. It also lists individual locations such as a toilet, the site of a former samurai residence, a small bridge, a pond, stairs, and a burial tower. Here, we record the contents of that page as rumors and do not treat them as factual phenomena or accidents.
Source of the rumor and date of verification
The source of the rumor is the Senshu Park page on the National Haunted Map website. The page was last updated on January 16, 2025, and the news section includes an article about an incident that occurred on April 27, 2020. This only indicates the description on the page and does not confirm the origin of the rumor or the official verification of the individual pieces of information published.
- Nationwide Haunted Map: "Senshu Park"(Confirmed on 2026-10-05) — Paranormal phenomena rumored to occur at Senshu Park: A female ghost appears. Senshu Park is said to be the place in the prefecture where the most spirits gather.
Things that could be confirmed from official and primary source materials
The Akita City official website describes Senshu Park as the site of Kubota Castle, the residence of the Satake clan, which existed from 1602 to 1869. It provides information on the park's development in 1896 based on a design by Nagaoka Yasuhira, its donation to Akita City by the Satake clan in 1984, its facilities, access, all-day opening hours, and water quality surveys of the outer moat. There is no official recognition of female or samurai spirits in the park. Senshu Park is a park developed on the site of Kubota Castle, the residence of the Satake clan, which existed from 1602 to 1869.
- Akita City Official Website: "Overview of Senshu Park"(Confirmed on 2026-10-05) — Senshu Park is the site of Kubota Castle, the residence of the Satake clan, who ruled the Akita Domain with a 200,000 koku (unit of rice production) for 12 generations and 267 years, from 1602 (Keicho 7) until the return of the domains to the Emperor in 1869 (Meiji 2).
Points of agreement/contradictions
Neither the claim of a female ghost nor the claim of a samurai from the Edo period is supported by the official website as a record of paranormal activity. On the other hand, official documents show that Senshu Park is the site of Kubota Castle from the Edo period, with specific dates, confirming the historical context of the term "Edo period" in a different sense. This is not a confirmation of the rumored ghost, but rather a new record of the land's history that was not mentioned in the rumor.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| A female ghost appears | Unconfirmed | The rumor page describes the appearance of a female ghost, but the official history and facility guide of Akita City does not contain any records confirming paranormal phenomena, making it impossible to compare them using independent sources. | No official data available for direct comparison. |
| The spirits of samurai from the Edo period have also been sighted there. | Unconfirmed | Official documents confirm the history of Kubota Castle ruins, not sightings of samurai spirits, and the chronological coincidence cannot be extended to support the existence of spirits. | No official data available for direct comparison. |
| The place in the prefecture where the most spirits gather | Unconfirmed | The comparative assessment that this park is the most haunted in the prefecture is limited to the description on the rumor page, and there are no indicators that can be measured or confirmed from the official park history or facility information. | No official data available for direct comparison. |
Alternative interpretation
It's possible that the historical and park-like landscape, including the castle ruins, moat, stairs, and pond, may have been the setting for stories and legends, particularly those related to nighttime impressions. However, the existence of these features alone cannot be used to infer evidence of ghost sightings or suicides. The official history should primarily be read as a record of the park and castle ruins.
Scope and limitations of the investigation
The sources I directly checked were the rumor page and the official Akita City overview page; I did not re-examine the information on the rumor page regarding the official gazette as an independent primary source. The absence of any mention of the strange occurrences on the official page is not refuting evidence. This analysis does not include any materials that provide a one-to-one correspondence between the rumored events and specific locations such as toilets, ponds, stairs, and slumber towers.
Verification results: New facts
Claims of ghost sightings or gatherings of spirits could not be compared with official documents, and only the age of the castle ruins could be confirmed as a meaningful public fact not found in the rumors. Therefore, instead of deciding whether the rumored supernatural occurrences matched or not, we decided to add the new fact of the land's history. This new fact does not prove the supernatural occurrences, but rather expands the scope of comparison with the rumors.

Safety information and maps
While the official website states that Senshu Park is open all day, this does not encourage nighttime ghost hunting. Please check for elevation changes such as moats and stairs, construction areas, and signs indicating restricted access, and use the park as usual, avoiding noise and trespassing on private property.
3rd Place: Omoriyama Park | Partial Match (78 points)
The rumored details
The rumor page states that a female ghost appears in Omoriyama Park. It mentions ghosts getting into cars late at night, and stories of people bringing ghosts home after returning. It also mentions an observation deck near the top of the park, which is a popular date spot because of the beautiful night view, but there are also stories of statues near the observation deck moving on their own. It recounts an experience where a group of four went but five people got out of the car, and states that the ghosts of suicide victims wander in the plum orchard on the mountain opposite the prefectural road. Here, we will treat everything as a description from the rumor page, and factual verification will be limited to cross-referencing with other sources.
Source of the rumor and date of verification
The source of the rumor was confirmed to be the Omoriyama Park page on the National Haunted Map. The page was last updated on May 7, 2023, and the post update information indicates that the initial registration was on February 4, 2021. While there are texts that present the phenomenon as personal experiences, independent records of occurrences or confirmation of the first appearance cannot be confirmed on the page, so it is classified as a secondary publication or of unknown origin.
- Nationwide Haunted Map: "Omoriyama Park"(Confirmed on 2026-10-05) — Paranormal phenomena rumored to occur at Omoriyama Park: A female ghost appears; human figures are seen. There is an observation deck near the top of the park.
Things that could be confirmed from official and primary source materials
The Akita City official website describes Omoriyama Park as a comprehensive park developed in a scenic area blessed with a rich natural environment, and provides information on a zoo, observation deck, and campground. The observation deck is located at the highest point of the park, at an altitude of 123.49 meters, and offers panoramic views of the city and the Sea of Japan, and is described as having a "group of mountains and sea" (a statue of a maiden). The website also provides specific details on campground plots, cooking facilities, fireplaces, toilets, application procedures, and precautions, but does not address the phenomena of ghosts or moving statues.
- Akita City Official Website "Omoriyama Park"(Confirmed on 2026-10-05) — This is the highest point in the park, at an elevation of 123.49 meters, offering panoramic views of the Sea of Japan and the city. It features the "Group Sculpture of Mountains and Sea" (Statue of the Maiden).
Points of agreement/contradictions
The structural claim that "there is an observation deck near the top of the park" is consistent with the official website's description of the observation deck as being at the "highest point of the park." However, the claims that a statue near the observation deck moves on its own, or that female ghosts or figures can be seen, are not supported by the official description. The structural consistency is limited to the description of the location and does not extend to supporting paranormal events.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| There is an observation deck near the top of the park. | support | The structural description of the observation deck on the rumor page matches the description of its target and purpose as stated by the official Akita City website, which states that there is an observation deck at the highest point of the park. | Akita City Official Website "Omoriyama Park" |
| The statue moves on its own. | Unconfirmed | The official website indicates that there is a "mountain and sea sculpture" at the observation deck, but it does not mention any events or observation records of the statue moving automatically. | No official data available for direct comparison. |
| A female ghost appears | Unconfirmed | The appearance of the female ghost is limited to the claims of the source of the rumor and is not a phenomenon that can be independently confirmed from the official Akita City park and zoo guide. | No official data available for direct comparison. |
Alternative interpretation
The observation deck overlooking the night view, the statue, the nighttime car traffic, the trees, and the elevation changes—all real-world elements—may have led to misidentification, altered memories, or anxiety in the dark. The existence of the statue as indicated in official documents does not mean that the statue moves automatically, and there are no records that can replicate the observations of on-site visitors.
Scope and limitations of the investigation
We directly compared the official Omoriyama Park website with the rumored pages. The official website shows the location and elevation of the observation deck and statues, as well as the conditions for using the campsite, but we did not verify the view of the night scenery or the rumored experiences regarding cars and the number of people. Videos and comments on the rumor pages were not treated as independent public records, and the claims of the plum orchard were also excluded from this analysis.
Verification results: Partial match
The physical structure of the observation deck is supported by official records, so we have determined that this claim is the only one that matches. On the other hand, the claims that the statue moves and that female ghosts or figures appear do not correspond to official records and remain unconfirmed. Since both supported and unconfirmed claims coexist on the same rumor page, the judgment is "partially matching," and the confirmation of the structure will not be treated as proof of the paranormal activity.

Safety information and maps
When using the observation deck or campsite, please prioritize following the official Akita City guidelines regarding applications, fire safety, littering, and noise. Avoid parking your car at night to verify rumors, trespassing into restricted areas or private property, and engaging in any behavior that may startle others. Please limit your activities to those of normal park use.
Map Location: The map anchor for Omoriyama Park is set to the coordinates of the observation deck at the highest point of the park.
What I learned by crossing locations
In all three locations, the rumor pages feature paranormal claims such as the presence of a female ghost, while the official pages describe the park's facilities, history, views, and usage conditions. At Senshu Park, the age of the castle ruins provides context for interpreting the rumored "Edo period," and at Omoriyama Park, only the structure of the observation deck matches the description in the rumor. At Hitotsumori Park, the facilities listed in the official overview do not confirm the rumors of tunnels or cemeteries. Therefore, physical similarities were treated not as proof of paranormal activity, but as the presence or absence of evidence for each claim.
summary
What we were able to confirm is that the three locations are listed as Akita City parks on the official website, the history of how Senshu Park was developed as the site of Kubota Castle, and that there is an observation deck in Omoriyama Park. On the other hand, the ghost of a woman, the shadowy figures, and the strange occurrences linked to the closed tunnel and cemetery could not be corroborated by the official documents we obtained this time. Since the situation may change due to updates to rumors and revisions to the official website, we will not enter the premises at night or trespass on private property, and when reconfirming, we will compare the claims on the same basis.
FAQ
What does "partial match" mean in this case?
At Omoriyama Park, only the description of the observation deck structure matched the official website. Claims that the statues move or that ghosts or figures appear have not been confirmed.
Are the new facts about Senshu Park proof of the supernatural occurrences?
No. It means that the age and history of the Kubota Castle ruins have been officially confirmed. It does not mean that there is any official recognition of the existence or sighting of spirits from the Edo period.
Is it okay to visit the place at night?
We do not recommend nighttime ghost hunting or approaching rumored haunted locations. Even if the park is open, please do not enter restricted areas or private property, and observe the rules for using each facility, such as regarding noise and fire.
