In defense of the Tokyo Metropolitan Government's recent move to tighten restrictions on graphic sexual content in manga and anime, Tokyo Gov. Shintaro Ishihara has said the conclusions he made in a 1972 book about sex education were wrong.
 
"I was wrong back then," Ishihara said during a regular press conference held on Dec. 17, referring to a passage in his book "Shinjitsu no Sei-kyoiku" (The True Sex Education), in which he claimed that "no book can motivate children to commit a crime or turn to juvenile delinquency."
