This study compares three locations in southern Kyushu and Okinawa that are known as haunted spots, based on information directly obtained from external rumor pages, publicly available documents from local governments or administrators, and publicly available geographical data on the same day. Rather than creating a ranking that definitively determines the presence or absence of paranormal activity, this study separates the historical, cultural property designation, excavation, and eyewitness accounts included in the rumors, and shows how well these can be compared with independent sources.
Survey methods and evaluation criteria
The descriptions on the rumor page were broken down not only into supernatural phenomena, but also into specific dates, location, cultural property designation, excavation, structure, and events, and each claim was compared with data from local governments, administrators, and publicly available geographical information. The judgment was as follows: "Agreement" if all claims were supported; "Partial agreement" if supported and unconfirmed claims coexisted; and "Disagreement" if even one claim was directly refuted. If neither support nor refutation was possible, it was marked as "Unmeasurable," and even if a direct comparison was not possible, if important designations, origins, or corrections not mentioned in the rumor were confirmed in independent sources, it was marked as "New Fact." In all cases, it represents the results of comparing the listed claims with the available data, not the existence of the supernatural phenomena themselves.
| Rank | point | The main points of the rumor | judgement | Document quality |
|---|---|---|---|---|
| 1 | Chibichirigama | The rumor posting page features "Chibichirigama/Shimukugama" under a single heading, describing Chibichirigama as a place where "unidentified spirits appear" and where "Chibichirigama is a place where mass suicides occurred during the war"... | New facts | 95/100 |

1st Place: Chibichirigama | New Facts (95 points)
The rumored details
The rumor posting page treats "Chibichirigama/Shimukugama" as a single heading, claiming that "an unknown spirit appears at Chibichirigama," "Chibichirigama is the site of a mass suicide during the war," and further, "half of the cave is called Chibichirigama, and the other half is called Shimukugama." This article focuses only on Chibichirigama, which could be identified using publicly available coordinates, and does not treat it as being the same location as Shimukugama.
Source of the rumor and date of verification
The rumor was confirmed on September 23, 2026, on the location-specific posting page of the National Haunted Map. Since the page itself lists both Chibichirigama and Shimukugama, I carefully read the descriptions to determine which location each one referred to.
- Nationwide Haunted Map: "Chibichirigama/Shimukugama"(Confirmed on 2026-09-23) — Paranormal phenomena rumored at Chibichirigama/Shimukugama: Unidentified spirits appear. Chibichirigama is famous as the site of mass suicide during the war.
Things that could be confirmed from official and primary source materials
Yomitan Village designated Chibichirigama as a village-designated cultural property and historical site on February 7, 2008. Furthermore, Yomitan Village's workshop guide lists the viewing order as "Chibichirigama → Shimukugama → Museum Lecture Room," listing both caves as separate viewing points. However, it is not a document that explains the underground structure, wartime events, or whether or not there were any strange occurrences. Nominatim registered Chibichirigama as the cave entrance in Namihira, Yomitan Village, with coordinates 26.4060506,127.7240646.

Points of agreement/contradictions
The claims about the appearance of strange phenomena, the explanations regarding the mass suicide, and the assertion that the two toads are physically connected and each half is called by a different name cannot be supported or denied based on the Yomitan Village documents obtained this time. On the other hand, the fact that it is a village-designated historical site and the date of designation are independent administrative records not listed on the rumor page, which provides material for understanding the place not merely as the setting for a ghost story, but as something to be preserved.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| An unknown spirit appears. | Unconfirmed | The Yomitan Village cultural property page and workshop guide do not contain any research records that support or deny the appearance of supernatural phenomena. | No official data available for direct comparison. |
| Chibichirigama is a place where people committed mass suicide during the war. | Unconfirmed | The Yomitan Village webpage obtained directly this time shows the designated categories and tour programs, but does not include the main text explaining this historical claim. | No official data available for direct comparison. |
| Half of the toads are called Chibichirigama, and the other half are called Shimukugama. | Unconfirmed | The official guide lists the two locations as separate sightseeing spots, but it doesn't explain whether or not they are connected underground. | No official data available for direct comparison. |
Alternative interpretation
The darkness, humidity, echoes, and complex footing of the cave entrance may influence perception and anxiety, but since this document lacks environmental measurements and testimonial verification from individual experiences, we cannot definitively conclude that these factors can explain specific experiences.
Scope and limitations of the investigation
While the Yomitan Village acquisition page indicates cultural property designation and tour programs, it is not a comprehensive research report covering underground structures, wartime history, or personal accounts. The primary testimonies and documents on which the claims on the rumor page are based are not clearly stated, and the veracity of the strange occurrences and historical descriptions remains undetermined.
Verification results: New facts
The three claims extracted from the rumors could not be directly supported or refuted by the official documents obtained this time. However, we were able to confirm an important administrative fact not mentioned in the rumors: that Yomitan Village has designated Chibichirigama as a village-designated cultural property and historical site with a designated date. This is therefore considered a "new fact." This does not prove that the phenomenon is supernatural.

Safety information and maps
This is a place for commemorating war dead and preserving cultural properties, and should not be used for dares or unauthorized entry. If a visit is necessary, follow the public information provided by Yomitan Village and the latest local announcements, and do not enter the cave entrance on your own.
Map location: Nominatim is the representative point identified as the cave entrance in Namihira, Yomitan Village.
2nd Place: Oyama Shell Mound | Partial Match (94 points)
The rumored details
Regarding the Oyama Shell Mound, the rumor page states that it is a "nationally designated historical site" and explains that "excavations conducted from 1954 to 1958" confirmed the presence of Oyama-style pottery, stone tools, bone and antler artifacts, and human remains. Furthermore, it includes visitor accounts such as "experiencing ringing in the ears and difficulty breathing around the shrine," and legends that the cave leads to the world of the dead.
Source of the rumor and date of verification
The rumor was confirmed on September 23, 2026, on the Oyama Shell Mound page of a website providing information on haunted places and ghost hunting. Because archaeological explanations, legends, and personal physical sensations are all listed on the same page, the claims were compared separately to avoid confusion.
- Information on haunted spots and ghost hunting: "Oyama Shell Mound"(Confirmed on 2026-09-23) — The Oyama Shell Mound, located in Oyama, Ginowan City, Okinawa Prefecture, is a nationally designated historic site that preserves artifacts from the shell mound period as well as traces of a burial ground from the Ryukyu Kingdom era. Excavations conducted from 1954 to 1958 unearthed Oyama-style pottery, stone tools, and bone and antler artifacts, which later became standard materials for Okinawan archaeology, and human remains were also confirmed in the rock shelters within the caves.
Things that could be confirmed from official and primary source materials
The Ginowan City Board of Education's Cultural Affairs Division lists the Oyama Shell Mound as a "National Historic Site" in the Oyama area. The Cultural Affairs Division's work records from June 2026 state that there is a walking path to the Oyama Shell Mound and that fallen trees were found in the opposite direction from the shell mound survey site after a severe storm. On the other hand, the city's document obtained this time does not contain any descriptions verifying the excavation details, traditions, or physical sensations from 1954 to 1958 mentioned on the rumor page. Nominatim returned the coordinates 26.2735683,127.7450614 as an archaeological site.

There aren't many large trees growing along the walking path, so the danger is probably minimal, but please keep it in mind when you visit.

Points of agreement/contradictions
The designation as a "nationally designated historical site" is consistent with the list of cultural properties in Ginowan City. The combination of excavation dates and unearthed artifacts is specifically described on the rumor page, but this cannot be confirmed on the city's page obtained this time. There are no personal accounts of tinnitus or shortness of breath in the official documents, and the silence in the official documents will not be used as refuting evidence. Therefore, only the historical site designation is supported, and the remaining claims remain unconfirmed.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| National Historic Site | support | The cultural property list compiled by the Cultural Affairs Division of the Ginowan City Board of Education clearly designates the Oyama Shell Mound as a nationally designated historical site. | Ginowan City "List of Cultural Properties in Ginowan City" |
| Excavation surveys conducted from 1954 to 1958 | Unconfirmed | The list of cultural properties and work records obtained directly from the city this time do not contain any text explaining the excavation surveys conducted during that period. | No official data available for direct comparison. |
| I experienced ringing in my ears and shortness of breath around the shrine. | Unconfirmed | The cited municipal documents deal with the designation and management status of cultural properties, but do not include records that verify individual physical sensations. | No official data available for direct comparison. |
Alternative interpretation
The sense of confinement, humidity, darkness, footing, wind, and insect sounds around the cave may affect physical sensations and hearing. However, without environmental data or medical information from the time of the experience, it is impossible to determine the cause of the tinnitus and shortness of breath reported.
Scope and limitations of the investigation
The list provided by Ginowan City is suitable for confirming designated categories, but it is not an individual excavation report. The Cultural Affairs Division's work records also focus on protection management and safety information, so other primary sources are needed for details on the year of excavation, unearthed artifacts, human remains, shrines, and local traditions.
Verification results: Partial match
Of the claims made on the rumor page, the fact that the Oyama Shell Mound is a nationally designated historical site was supported by documents from the Cultural Affairs Division of the Ginowan City Board of Education. On the other hand, details of the excavation date, unearthed artifacts, and personal accounts of physical sensations could not be confirmed in the official documents. Because supported and unconfirmed claims coexist, it was marked as "partially consistent." This does not imply the existence of the supernatural phenomena.

Safety information and maps
Prioritize the preservation of the nationally designated historical site and refrain from entering caves or areas outside of the publicly accessible zone. The Ginowan City Cultural Affairs Division has also mentioned the risk of fallen trees after severe weather, so check the latest management information before visiting and avoid approaching the site after bad weather or at night.

3rd place: Hitotsuba Coast | Unmeasurable (85 points)
The rumored details
Regarding Hitotsuba Beach, the rumor page states that "a female ghost appears there," and that "people with psychic abilities who go to the sea at night can see a ghost approaching them across the sea." The page also lists the address and coordinates of Awagihara-cho, Miyazaki City, but it does not provide any primary testimony, date, time, or observation conditions to support the two claims of paranormal activity.
Source of the rumor and date of verification
The rumor was confirmed on September 23, 2026, on the Hitotsuba Coast page of the National Haunted Map. The location name, address, coordinates, and two descriptions regarding the female ghost were extracted from the page text and treated as a rumor record separate from the administrator's materials.
- Nationwide Haunted Map: "Hitotsuba Coast"(Confirmed on 2026-09-23) — Hitotsuba Beach is a haunted spot by the sea in Miyazaki City, Miyazaki Prefecture. It is known as a haunted spot because of rumors that a female ghost appears there. It is said that people with psychic abilities who go to the sea at night can see spirits approaching across the sea.
Things that could be confirmed from official and primary source materials
Regarding Sun Beach Hitotsuba, which is managed around Hitotsuba Beach, the Miyazaki Seaside Park administrator page describes it as the only artificial beach in Miyazaki Prefecture, stating that the northern side is used for marine sports and the southern side for swimming, and that it is equipped with toilets, showers, a green space, and a parking lot. This document describes the nature of the managed area, but does not mention the female statue or the statue approaching the sea on the rumor page. Nominatim returned 31.9285910,131.4682146 as the representative point for the surrounding managed area, Miyazaki Seaside Park.
- Miyazaki Seaside Park "Sun Beach Hitotsuba"(Confirmed on 2026-09-23) — "Sun Beach Hitotsuba" is the only artificial beach in Miyazaki Prefecture. The northern beach is popular for marine sports, while the southern beach is a popular swimming spot. The beach is equipped with toilets, showers, a green space, and a parking lot, making it a great place to enjoy picnics and water activities all year round, not just during the summer swimming season.

Points of agreement/contradictions
Regarding the claims on the rumor page that "a female ghost appears" and that a figure can be seen approaching from the sea, the administrator's documents neither support nor deny these claims. The fact that the beach is developed as an artificial beach and used for multiple purposes explains the environment of the location, but it is not evidence that paranormal phenomena occur or do not occur. Therefore, neither of the two claims can be directly compared.
| The rumored atomic claim | Matching results | reason | Corresponding documents |
|---|---|---|---|
| A female ghost appears | Unconfirmed | The facility manager's public page describes the beach's uses and facilities, but does not mention any observations or investigations regarding the female ghost. | No official data available for direct comparison. |
| I can see spirits approaching from across the sea. | Unconfirmed | Aside from the rumor page, there is no independent documentation showing the observation date, time, or conditions, and it is not possible to support or refute it from administrator documents. | No official data available for direct comparison. |
Alternative interpretation
Low light levels at night, reflections from the wave surface, the sound of the waves, distant lighting, and the movement of people could all affect visibility. However, without the rumored sighting time, weather conditions, viewing distance, and video footage, it is impossible to attribute it to a specific natural phenomenon.
Scope and limitations of the investigation
The administrator page is a document that provides information about the facility's purpose and equipment, not a report investigating nighttime sightings. The rumors page also lacks information that can identify witnesses or verifiable observation records, making it impossible to support or refute either of the two paranormal claims.
Verification result: Unmeasurable
While administrator documents confirmed the existence of an artificial beach and management facilities around Hitotsuba Beach, this does not provide evidence for rumors about a female statue or a statue approaching the sea. Since there are no independent records supporting or directly refuting the two claims, and no significant corrections or origins not mentioned in the rumors were obtained, the matter was deemed "unmeasurable."

Safety information and maps
Poor visibility at night, high tides, waves, and strong winds can pose dangers on the coast. Follow the latest information on managed areas and operating hours, do not enter areas outside of swimming zones or during rough weather, and avoid making solitary nighttime visits for the purpose of investigating strange occurrences.
Map Location: For the area around Sun Beach Hitotsuba, as confirmed in the administrator's documents, the Nominatim Miyazaki Seaside Park representative point was used as the map reference point.
What I learned by crossing locations
While no text was found to corroborate the claims of strange occurrences or wartime events at Chibichirigama, the important information not found on the rumor page—the date of designation as a village-designated historical site by Yomitan Village—was confirmed, so it was classified as a "new fact." Regarding Oyama Shell Mound, only the claim that it is a nationally designated historical site matched the Ginowan City document; details of the excavation and personal accounts could not be confirmed in this document, so it was classified as "partially consistent." At Hitotsuba Beach, the managed area and coordinates were confirmed, but there were no records supporting or refuting the two claims of strange occurrences, so it was classified as "unmeasurable." The ranking of document quality was based not on the strength of the strange occurrences, but on the independence of the source, context, safety information, time of confirmation, and transparency of the rumor page.
summary
What we were able to confirm this time was the administrative designation of Chibichirigama as a cultural property, the status of Oyama Shell Mound as a nationally designated historical site, and the managed area and public coordinates around Hitotsuba Coast. No official records supporting the paranormal experiences were obtained for any of the three locations, and the silence of official documents is not considered to be refuting evidence. Historical and cultural sites should not be used as targets for recreational ghost hunting, and priority should be given to the public area, guidance from managers, and safety in terms of weather and footing.
FAQ
Does "match" mean that the supernatural phenomenon is real?
It does not mean that. This article's judgment only indicates whether the individual dates, specifications, events, and personal accounts extracted from the rumor page match the independent sources cited.
How did you find the coordinates on the map?
Each location name and region was matched against the publicly available search results on Nominatim, and the same latitude and longitude returned were set for both the Google Maps embed URL and the search URL.
Is it alright to visit the location at night?
This does not guarantee nighttime visits or access. At cultural sites, memorial sites, cave entrances, and coastlines, you should check the latest information from the administrator, the areas open to the public, the weather, and the footing, and avoid unauthorized entry or daredevil activities.
