The regulation was proposed by Tokyo metropolitan government and it intends to restrict the minor characters appearing in manga, anime, movies, and games. Even if the characters are described as adults in the story, Tokyo will judge whether the characters are considered to be minors based on the appearance, backgrounds, and voices. Those characters are defined as "fictitious juveniles" and Tokyo will restrict the sales of the media if it contains sexual expressions of "fictitious juveniles". Mangaka and their supporters are apprehensive that the interpretation of "sexual expressions" can be expanded limitlessly.
The ordinance will be put to the vote on March 19th.
