AI: The Somnium Files Wiki

Tokyo, Japan is the main setting of the AI: THE SOMNIUM FILES series.

It is based on the real life Tokyo Metropolis, set in modern times but with certain technological advances in some areas.

Various events have occurred within the city of Tokyo, such as the Ujisaki Family Turf War, the Kabasaki Chemical Plant Explosion, both the Original and New Cyclops Serial Killings, and the Half Body Serial Killings.

Detailed Tokyo Map.jpg

Central Tokyo is made up of 23 Wards (referred to as Districts in AI: THE SOMNIUM FILES), and each Ward has its own set of Districts and have their own small government facility for council. As displayed on the Tokyo map at Boss's Office, all 23 Wards are present in AI, but only some are directly mentioned in-game. The districts are:

  1. Adachi District
  2. Arakawa District
  3. Bunkyo District
  4. Chiyoda District
  5. Chuo District
  6. Edogawa District
  7. Itabashi District
  8. Katsushika District
  9. Kita District
  10. Koto District
  11. Meguro District

  13. Nakano District
  14. Nerima District
  15. Ota and Shinagawa Districts
  16. Setagaya District
  17. Shibuya District
  18. Shinjuku District
    • Golden Yokocho
      • Snack Marble
      • Queen Phantom
      • Other locales

    • Unspecified District
      • Dora Dora Mahjong Parlor
  19. Suginami District
  20. Sumida District
  21. Taito District
  22. Toshima District

Along with the 23 Wards that make up Central Tokyo, there is also Western Tokyo, made up of several other cities and towns. While there are 26 cities in Western Tokyo, only one of them is ever mentioned in the story, as there are no maps to indicate any locations:

The following is a list of people who live or have lived in Tokyo at some point in the history of this world.

Trivia[]

  • The Ota and Shinagawa Districts are never mentioned by name in AI: THE SOMNIUM FILES, instead always referring to the island that both districts share as the Kabasaki District. Despite this, the names "Ota District" and "Shinagawa District" appear in Japanese in the map found in Boss's Office. This odd omission is most likely due to the name of the Ota District, which is pronounced the same (but written differently) as the name Ota Matsushita.

  1. In the chapter Day 3: Sunday –gyoukAI–, Hitomi Sagan explains that the Okiura family moved to her school district so that Mizuki Okiura could attend the school Hitomi teaches at. Shoko Nadami is confirmed to live in the Meguro District as well, but Mizuki's legal guardian is Renju Okiura, meaning his place of residence is also in the Meguro District, so that the school system can recognize Mizuki as eligible for Hitomi's school, despite actually living in the Koto District with Kaname Date.
  2. It's unclear whether the Lemniscate Entertainment Offices is located in the Shibuya District or the Minato District, as the location borders both districts. The most likely scenario is that it's in the Kitaaoyama/Minamiaoyama, which are partially commercial districts, as the closest area in the Shibuya Distirct, 3-Chome and 4-Chome Jingumae, is more residential without many tall buildings.
