One of the really big differences between Japanese and American broadcasting is the relative lack of reruns on Japanese TV. With four, roughly 13-week seasons a year, and not nearly the plethora of channels available in the U.S., Japanese TV series, anime included, tend to chug straight from start to finish, and once they’re done, if you want to see an episode again, usually your only choice is on DVD or Blu-ray.
Once in a while, though, smaller carriers will pick up a series for rebroadcast after it’s finished its initial run. It’s a rare occurrence, though, so a recent poll asked anime fans which series they’d most like to see shown on TV one more time.
