Tokyo



Kaidan is introduced in Ground Zero the flashback at the beginning of the game, where the Bee recruit "possesses" a Secret World team member, but after that, Japan is only hinted at until the beginning of the Black Signal story arc.

Tokyo, both Kaidan and the Orochi Tower areas, were the only normal mission playfields not released in the original game. Except for Tokyo, only missions, and other content such as Raids and PvP areas, were added in update patches.

After Romania via Venice (Venice Sinking), the arc returns to Tokyo with Back to the Beginning. It continues with Runaway Circus, an introduction to Gozen and the Jinku clan base in Kaidan: The Right of Way

"Kaidan is a Japanese word consisting of two kanji: 怪 (kai) meaning "strange, mysterious, rare, or bewitching apparition" and 談 (dan) meaning "talk" or "recited narrative." Hyakumonogatari Kaidankai, the name for Harumi and Yuichi's apartment complex, also means something relevant to The Secret World in Japanese.

Tokyo missions, especially the Harumi ones, are often as altruistic as they are informative, and in these cases the Illuminati faction Upload messages have an impatient tone, disdaining the relevance of unpaid work.
