Yeah, well, Hitler isn't the central, really. It mostly focuses on the Japanese reporter and the two German friends. At least in volume 1. The reporter attends a 1936 Nazi rally (I believe it was the same one that Leni Reifenstahl filmed for "Triumph of the Will") Hitler gives a speech there and Tezuka gets a little cartoony drawing his exagerated gestures. Then in the next volume, there's a scene where the German boy who's friends with a Jewish boy and is sent to the Hitler Youth against his will, scores the highest in his class and gets to shake Hitler's hand at a ceremony. I've only seen that page and read about it in a review, I haven't read the second volume yet.
