Yamijima Island (夜見島 Yamijima?) was a remote island that was located off the coast of Japan. The island is filled with unsociable and unique customs, and went through huge changes along with the trends of the generation. All that remains in this area, with its horrible history, is the silent passage of time, and the remnants of the mystery of 29 years ago. It serves as the main setting for Forbidden Siren 2.

History[]

Post- World War II[]

During World War II, Yamijima island was a secret site for the Japanese military to produce "Chemical weapons" in a secret poison factory. The chemical weapons were mainly stored in the Fort Ruins located in Kaioizaki. Residents and potential employees were not told what the plant was manufacturing, and everything was kept secret. Working conditions were harsh and many suffered from toxic-exposure related illnesses due to inadequate safety equipment.

However, when the war ended in 1945, documents concerning the plant were burned and Allied Occupation Forces disposed of the gas either by dumping, burning, or burying it. People were told to be silent about the project, and several decades would pass before victims from the plant were given government aid for treatment.

The real Yamijima[]

Yamijima was a place that has felt the influence of a supernatural being called Annaki (and the things created from its bones), and as such has been feared since ancient times as "the island of darkness", "island of the underworld" and "the taboo island". This is due to the fact that Mt. Shinari in the center of the island and the Mekkoju, which exists in the World of Nothingness, was once overlapped in their dimensions, leading the Islanders to develop unique traditions and legends involving "impurity", and several strange incidents such as the mass disappearances and undersea cable cutting off 29 years ago occur on Yamijima because of the special location in which it is positioned.

The Ohta family is in charge of the fishing industry on Yamijima. The chief owns the boats, nets and other equipment, lending them out to the fishermen in his employ.

The Yamijima Island Reality []

Is a reality/dimension created by Mother in 1975 at midnight when Kanae, a Mother Avatar, was unable to complete her mission when a red tsunami engulfed the Island. The entire population of Yamijima were whisked into this world, except for Shu Mikami and Kanae, who escaped by boat. To the people in the real world, the island was deserted. A loose underwater cable was used to explain the power outage the island suffered from in this event, but an explanation of the disappearance of the people themselves was left unanswered.

The creation of this dimension meant that the real Yamijima island was folded in time, allowing people from different time periods to co-exist on the island. The ultimate purpose of this reality is to ensure that Mother uses it as a means to escape into the real world through Spider's Thread.

This reality is depicted as the same as the real Yamijima, including buildings, items and areas. When the red tsunami struck the real Yamijima, everyone on the island believed it was the real island, although Yuri Kishida reveals that this world is unstable. Even though its properties are the same as its real counterpart, time can allow something as small as a glass ornament to reappear whole after shattering into pieces.

Ultimately, this reality was unstable due to the time-fold, which meant that sooner or later, this reality would revert to what it once was - nothing. As Spider's Thread collapses, Mother sends herself, Mamoru and Ikuko into her world, a red rocky dimension with red water as a sky. Eventually, after her defeat at their hands, a red tsunami appears and plunges the survivors into different worlds: Mamoru Itsuki, Ikuko Kifune, Soji Abe and Tsukasa are sent to a world where Mother and her avatars never existed, whilst Yorito Nagai ends up in a world where humans are old myths and Yamibito walk among like humans.

1976 Yamijima Blackout Incident:[]

On August 3, 1976. A large blackout occured on Yamjima Island due to a severed underwater submarine cable. Surprisingly, all the residents that lived on the island have also disappeared overnight. The next morning, A repair crew from Sanzu Electric Power company contacted police after arriving on the island that was left deserted.

Following the mysterious disappearance of all the islanders, the Tokyo Metropolitan Police Department setup a Joint taskforce, hoping to find any survivors left on the island. Unfortunately, since no survivors were found, the case was eventually closed. Because of this incident, Yamijima Island was closed off to the rest of the world.

According to a spokesman of the Sanzu Electric Power company, the estimated submarine cable lies at a maximum of 310 meters, which it would require a large number of trained personnel and advanced equipment to cut the cable. Because of this maximum level, it would be impossible for the cable to be severed.

Aftermath[]

After the deaths of Otoshigo and mother, Yamijima Island is completely freed from the underworld. However, it will still be closed off to the rest of the world forever.

Trivia[]

  • The discussion of the name "Yamijima" in the archive item 66 is actually a parsing of the kanji readings used. The official kanji are "night (ya) 夜 / see (mi) 見 / island (jima) 島", which is not particularly bizarre. The same pronunciation can be achieved using the kanji for the words above: "evil (yami) 闇 / island (jima) 島", for example.) 
66 Yamijima history

Item 66; Local history of Yamijima

​​​​​​...Regarding the origin of the name "Yamijima", there are theories suggesting it derives from the terms "The Isle of Hate", "The Isle of the Dead" and even "The Isle of Evil". As these theories suggest, the island has long shunned outsiders.'(...omission...)
Given the residents' unusual folklore and customs, there was little mingling with outsiders. However, thanks to the booming gold mining industry, the number of people immigrating from the mainland rose dramatically and brought huge changes to the island.
  • Both Hanuda and Yamijima had a past related to minery, while Hanuda had Tin mines, Yamijima had gold mines.
  • Both Hanuda and Yamijima have a special dish; Hanuda has the Hanuda noodles, while Yamijima has the Yami Nabe.
Item 58 Yami Nabe
A local delicacy, native to Yamijima, made from seafood and mountain ingredients. Custom dictates that the ingredients remain untouched by cutlery, and that the dish be eaten under moonlight. The best version uses Yami Akebi, which induces intense feelings of euphoria lasting an entire evening. However, the next morning can be hell for unlucky diners.
38 Yami Akebi
Part of the Akebi family, a deciduous creeper.
This is a unique Akebi native only to Yamijima. The fruit is notable for its peculiar bittersweet taste. As ingestion can cause severe diarhhea as well as a number of hallucinogenic effects, caution should be taken when using it in food preparation.
