The series ran for 47 episodes when it was first broadcast back in 1980 with TMS working on the animation.
While Crunchyroll began streaming this series back in March 2014, Amazon Prime is now beginning to stream Champion Joe 2, aka Ashita no Joe 2, on their service via owner TMS Entertainment.
The first twelve episodes of the series were previously started to come out back this past summer, but it wasn’t a complete presentation of it.
Now, the full first set of twelve episodes are streaming in its original Japanese language with English subtitles.
