Wanted to talk about that yesterday but schedule was a bit tight.
Most of you probably heard of this “Ordinance Bill” already, but I believe it is way too important not to write something about it, just in case you were unaware of the following.
Instead of putting my own words to describe what this “bill” is all about, I chose to quote the news posted on ANN directly, because I think they summed it up very well :

December 15th 2010

The full Tokyo Metropolitan Assembly approved the government’s revised bill to amend the Youth Healthy Development Ordinance on Wednesday afternoon.

The current ordinance already prevents the sale and renting of “harmful publications” — materials that are “sexually stimulating, encourages cruelty, and/or may compel suicide or criminal behavior” to people under the age of 18. Bill 156 would require the industry to also regulate “manga, anime, and other images (except for real-life photography)” that “unjustifiably glorify or exaggerate” certain sexual or pseudo sexual acts. Another section of the revised bill would allow the government to directly regulate the above images if the depicted acts are also “considered to be excessively disrupting of social order” such as rape.

The assembly also approved a non-binding supplemental resolution urging newly designated harmful publications to be carefully regulated, with the work’s merits based on artistic, social, and other criteria to be taken into account in the evaluation process.

The voluntary self-regulation clauses will go into effect on April 1 of next year, and the restrictions on sales and renting will go into effect on July 1.

I don’t think there is a need to tell you what huge impact this’ll have on future Animes/Mangas.
Needless to say, many people are strongly against this ordinance’s revision, starting with Jump, who clearly stated :

“Don’t let the chilling effect [of increased regulation] stop you from doing material you want to do. Jump will feature anything [we feel] that is exciting [to read].“

Things are likely to escalate in the following days, since this revision is killing a non-negligible part of the anime/manga industry, and all its extensions (anime fairs, comiket, any probably many more).
