Originally located in the New Tokyo system, Fuchu Prison was moved to the Shikoku system in 600 AS to handle the burgeoning foreign criminal element that was plaguing the area. While nearly 70% of the prisoners are from outside of Kusari space, the remaining 30% are almost exclusively members of a radical, political terrorist group called the Blood Dragons. "Rehabilitation through work" is a core principal of the Fuchu Prison mandate, and inmates are routinely deployed to mine Hydrocarbons and work the Junyo fishing platforms.
