According to Nikkei newspaper, the recent administrative discussion boards on the regulation of child porn have refrained from bringing the anime issue to the subject. Tokyo metropolitan government is still seeking a chance to reintroduce the so-called "Anti Fictitious Juvenile Porn" bill, which was rejected last summer. However, the Japan Committee for UNICEFF has removed anime and manga from their statement about anti child porn law although the NGO had been the vanguard of the movement. Kyoto Prefecture has also decided to put anime and manga outside the scope of the law.
Lawyers have pointed out that it's against the Constitution of Japan to restrict the freedom of expression which doesn't violate the human rights of existing children.
