Picture taken inside SCP-6979-1, in the area of Meguro City, Tokyo

Special Containment Procedures: SCP-6979 is to be followed and intercepted on each of its manifestations. SCP-6979 has been equipped with a tracker and an interdimensional translocating device has been built inside SCP-6979-1, allowing for SCP-6979's geopositioning regardless of its current dimensional location. The tracker is to be equipped inside SCP-6979-1 following every manifestation, with a kit to build it given to the intercepting team's designated engineer. The designated engineer must also perform maintenance work on the translocating device.

SCP-6979-1 is currently inaccessible without the help of SCP-6979, and thus does not need containment. Its current extent and population, however, has not been confirmed, and is expected to remain unconfirmed for the foreseeable future. Due to it possibly being able to affect the entirety of the entire territory of Japan, its disruption and risk classes have been adjusted accordingly.

Description: SCP-6979 is a selectively corporeal humanoid entity that resides within SCP-6979-1. Its appearance is that of a stereotypical yūrei ghost, with a disfigured face and long claws. It is able to manifest within the Greater Tokyo Metropolitan Area by assuming the form of the "Kuchisake-onna" (口裂け女, "Slit-Mouthed Woman"), an entity of urban folklore, to then follow its behavior. SCP-6979 used to attack and kill people, intercepting the entity having lowered these attacks to zero. This attack method was used by SCP-6979 as means of subsisting, feeding on ‘belief’, ‘belief’ in this case referring to the understanding of a concept as true.. This concept doesn’t need to be ‘real’ to be considered true (e.g., SCP-6979 uses an urban legend to materialize, which isn’t believed to be ‘real’ but exists within our reality as folklore.) This ‘belief’ is emitted by humans and converted into Landa particles.Anomalous particles known to contaminate measurements of Akiva radiation. Seem to be correlated with expressions of folk-belief and/or superstition. through unknown means.. It must be pointed out that the ‘belief’ consumed by SCP-6979 isn’t created by the victims of its attacks, and thus stopping them seems to cause it no harm. This feeding process as well as the exact function of Landa particles isn’t well understood.

SCP-6979 has proven cooperative with Foundation assets, although it can become distant and aggressive at times, especially around armed personnel. This is believed to stem from SCP-6979-1’s occupation by IJAMEA between 1930 and 1939, which caused the death of all other inhabitants of SCP-6979-1. (Hereafter referred to as SCP-6979-2.)

SCP-6979-1 is an extradimensional space known as Mamonokai, believed to be coextensive to the total territory of Japan, of which less than 1,000 km2 have been explored. The location is an identical copy of Japan, with a few key exceptions:

  • The sun is static over the horizon regardless of the time or location. Light within SCP-6979 is red, despite wavelength inconsistencies.
  • All ground and soil is either covered in or replaced by soot. Analysis shows the soot to be the remains of Aquilaria trees, genus not endemic to the Japanese archipelago.
  • All bodies of water are dark black, despite not containing any sort of contaminant.
  • All buildings are identical in architectural shape to their counterparts, but are built using materials and techniques from the Muromachi, Azuchi-Momoyama and Edo periods (1336-1868).
  • All electronic devices suffer damage to internal parts, especially on power sources following travel into SCP-6979. While previously believed to be because of a high-energy EMP, this was proved to be incorrect, and electronic devices that are separated from power sources suffer no damage. This only affects devices when entering into SCP-6979, and causes no damage when egressing.
  • Hume levels are lower than those of baseline reality, fluctuating between 0.75 and 0.85 humes.

Access into SCP-6979-1 is only available through SCP-6979 by means of direct contact with the entity during demanifestation. Portals are known to have existed in the past, but were sealed by IJAMEA, causing a full separation between SCP-6979-1 and our world..SCP-6979 is able to traverse between worlds. The entity has no control over this process, only occurring when SCP-6979 begins running low on ‘belief’. The first occurrence of this happened in 1979, and is believed to be linked with a weakening of the seals placed by IJAMEA. A way to reactivate these portals is currently under research.

Discovery: SCP-6979 was first discovered in 1979, but its true nature and SCP-6979-1 were not discovered until 2014/06/25 when a D-class subject approached SCP-6979 and was taken into SCP-6979-1. A ritual was performed to learn SCP-6979’s next manifestation, which occurred 191 days later. A group was set to intercept the event, with Folklore Department researcher Zhou Yuyan and two others entering its dimension. An interview with the entity was carried out while inside:

Following the exchange, SCP-6979 took the personnel to a location in Nakano Ward, where another IJAMEA outpost was located. No information was obtained from this visit. After 6 hours, Foundation personnel returned from SCP-6979-1, not before establishing current containment procedures, SCP-6979 accepting the use of a translocating device. Device would be implemented during the next visit, with containment technician Ariella Concepción tasked with maintenance of the tracker.


Tanaka Hachiman shrine.

Addendum SCP-6979.1: During an expedition into SCP-6979-1 made on 2017/08/01 with the purpose of exploring the neighbouring Kanagawa prefecture, an IJAMEA outpost was discovered in the city of Yamato, located within the Tanaka Hachiman shrine (35°26'28.0"N 139°27'39.9"E). This outpost was a portal location, and unlike others previously discovered, contained information regarding IJAMEA activity inside the dimension. A partial transcription of pertinent documentation can be accessed below. For the full list, contact Dr. Zhou.

Following this discovery, a team was sent to the Tanaka Hachiman shrine to excavate the area, discovering the desiccated corpse of a small entity, believed to be the Zashiki-warashi mentioned in the report.

With the use of this corpse, and with the help of GoI-921 ("Shūshū-In"), Project Kakurenbo was able to build machinery capable of reopening and maintaining the sealed portals into SCP-6979-1. Using Scranton Reality Anchors as base, the system was capable of siphoning and maintaining a constant reality flow between the two areas. This system, named the Çağlayan Reality Diffusion System (ÇRDS), was tested under controlled conditions, passing all tests. It’s believed it’ll be ready to be deployed within the first half of 2019.

Addendum SCP-6979.2: On 2019/04/11, the ÇRDS was deployed, successfully opening a portal into SCP-6979-1. SCP-6979 and SCP-6979-1 suffered no adverse effects, with SCP-6979 mentioning ‘Mamonokai is breathing again’. Since the opening of the portal, SCP-6979 has not manifested as the 'Kuchisake-onna' entity, claiming ‘there seems to be no need anymore’.

Since then, vegetation has begun growing inside SCP-6979-1, and the colors of the sky and the sea have slowly changed into more natural hues. SCP-6979-1 is currently being explored, the territory of Japan believed to be fully surveyed within 5 years. Reclassification is expected to occur after this period.
