Tokyo Metropolitan Ordinance Regarding the Healthy Development of Youths, bill 156. 2010.


On 24 February 2010, the Metropolitan government submitted a proposed revision to the ordinance that would restrict sexually provocative depictions of fictional characters who appear to be under 18 years of age, referred to in the bill as "non-existent youths". This proposal was criticised by many manga authors and received strong opposition from the publishing industry, the Writers Guild of Japan and the Japan Federation of Bar Associations, and was rejected by the Tokyo Metropolitan Assembly on 16 June 2010
Voting on the bill was put on hold until June,[9][10] and Shintarō Ishihara, the governor of Tokyo, admitted that the bill's language needed revision.[

Bill 156 was approved by the Metropolitan Assembly's general affairs committee on 13 December 2010 and passed by the full Assembly two days later
