When I heard about this, I was floored. At the height of the Adam West Batman show Japan was given full license by DC to create a Batman Manga “adaption”. I use the term adaption loosely for reasons you’ll see shortly. Western audiences weren’t privy to much information about this until the 2008 publication of Chip Kidd’s Bat-Manga!: The Secret History Of Batman in Japan book blew the lid off it. This gave the world some context and background and the first translations of artist Jiro Kuwata’s fabled Batmanga stories albeit incomplete.
DC got the hint though and have started a campaign to release the Batmanga across 3 trade paperbacks in its complete form for the first time. The first two have seen release with the third getting put out near the beginning of 2016. I recently sat down and took Volume 1 head on.
