Kitaro returned for a fourth series in the 1990s, again with a new cast and new production team. Manga creator Shigeru Mizuki was a big fan of director Hayao Miyazaki, and influences from the latter can be seen in some of the character designs and in the environmentally conscious themes of this series. While tastes may differ, for some fans this is the definitive version of the GeGeGe no Kitaro anime.
Here's a batch of remastered episodes, plus two new ones. In episode 9 Rat Man tries to flee loan-sharks by taking the last train to a nearly abandoned rural village, only to find himself part of an attack on Japan by elderly vampires. Episode 10 starts out as a tale about Nezumi Otoko trying to sell a haunted house, but takes an interesting turn, exploring the unlikely friendship between a giant bamboo Yokai and a frail, lonely girl struggling with poor health.
