The Ordinance was controversially revised in December 2010 to expand the definition of "harmful publications" and to give the Metropolitan government greater powers to enforce the law's provisions.
According to Michiko Nagaoko, director of a non-profit organization in Kyoto called Juvenile Guide, founded in 2003, approximately half of the 2,000 pornographic animation titles distributed in Japan every year, including films and video games, feature schoolgirl characters.
[4] 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" (非実在青少年, hijitsuzai seishōnen).
[17] It removed the controversial "non-existent youth" term but still proposed a number of significant changes to the law:[18] Like its predecessor, the bill was opposed by many writers, publishers and lawyers.
[22][23][24][25][26][27] The committee added a non-binding clause to the bill that calls on regulators to take into account "merits based on artistic, social, educational, and satirical criticism criteria" when evaluating publications under the revised law.
Secondly, because the restrictions would only apply to manga and anime, he viewed the bill as discriminating against those specific mediums while ignoring content from films or novels; noting how Ishihara was formerly a novelist himself.
[37] In a blog post on 13 December 2010, the Japanese Prime Minister Naoto Kan expressed concern about the impact of the boycott and urged the parties involved to work towards resolving the situation.
[30]After some publishers asked for a list of standards required by the newly revised bill before they start the sale of a book, Mika Sakurai, the section chief of youth affairs at the Office for Youth Affairs and Public Safety, stated that the publishers can ask the government whether or not a specific work is subject to the law before sale, but a response might not be immediate as "the assessment may not be clear until release".
[42] One week after the meeting, Masahiro Itosugi, the author of the listed work Aki Sora, announced that there would be no further reprints of volumes 1 and 3 of the manga after the law goes into effect in July 2011.
[43] In March 2013, manga artist Yuzupon claimed on their Twitter account that the first volume of their work Welcome to Sugarpot, which was released about a month earlier, had been withdrawn from stores due to the Tokyo bill.
[44] In May 2014, the Imouto Paradise 2 manga became the first work to officially be restricted as "unhealthy" in Tokyo under the 2010 revisions to the youth law for "glorifying incestuous acts".
