The Konoha Strict Correctional Facility (木ノ葉厳重警戒施設, Konoha Genjū Keikai Shisetsu), which only appeared in the anime, is a place where shinobi who have committed serious crimes work off their debt to society. In the past, this place used to be called the Special Ninja Felony Prison. However, due to reduced crime rate, the prison was rebuilt into a smaller facility and renamed.
The prison houses murderers and missing-nin who have broken the law. Known inmates of this facility are Mizuki, Fūjin and Raijin. Mizuki manipulated the two brothers to help him break out, but all three of them were eventually recaptured.
