At the Toonami panel at the MomoCon anime convention in Atlanta this past weekend a fan asked if they had plans to play the new Sailor Moon anime that will begin airing in Japan this summer. Toonami’s response was only that they were considering it.
Nothing is definitive at this point but Toonami would certainly be a fitting home for the new 2013 Sailor Moon anime as many American fans were first exposed to the original Sailor Moon anime on Cartoon Network’s Toonami block when they started airing the show in June of 1998. The Toonami block of programming, which centres around more action oriented animation included a lot of Anime, returned to Cartoon Network last May after a long hiatus.
