There's a Japanese site (which is accessible unless blocked beyond control) called Niconico which hosts these kinds of videos, and more professional streaming sites such as the Crunchyroll (under acquisition by Sony), Funimation (subsidiary of Sony) or the Japanese Hulu (under control of NTV, a Japanese media conglomerate). In other words, I don't think YouTube has a chance here, unless they were technically under Play Movies.
