In a switch from the usual Japan has everything before us- the anime Afro Samurai will debut in Japan screens come this month (we already got it here in US- ha!).
GONZO animation studio created the series based on a doujinshi by Takashi Okazaki.
Voice Actors include Kelly Hu (XMEN 2) and Samuel L. Jackson as Afro and Ninja Ninja.
The anime is available from Amazon and I Tunes, in case you missed it on Adult Swim.
