The government admitted Tuesday that it failed to acknowledge in a variety of state booklets and videotapes that it was responsible for the forced isolation of Hansen's disease patients in the past.

The contents of the booklets and videotapes in question were revealed in a government response to questions from Renko Kitagawa, a House of Representatives member of the Social Democratic Party.

The booklets and the videotapes were prepared by the Cabinet Office and published in cooperation with the Health, Labor and Welfare Ministry and the Justice Ministry's Civil Liberties Bureau.
