The main story is about the raccoons and in minor the foxes, this story is as if the what the legends about raccoons and foxes were true, they can transform. The raccoons start realizing there land is getting smaller, and have a few leaders journey to the best transformers, the younger generation practice transforming, and during spring do NOT procreate.
Pom Poko goes through 2-3 years during the development of the town. The raccoons try many ways to scare the people away, and work on a few people but all it did was made more people move in.
The leaders finally show up after a year, and they help create a scary parade, which people thought it was a gimmick which a theme park took credit for it. the raccoons pretty much give up, but then the foxes show up and try to make a deal for the raccoons that can transform pretend to be humans and live among us. which means the ones that can't they would have to let die.
The raccoons do one last thing and transform the hills back to the original way, just for one last moment in there old lives. The ones that can transform live among humans, the others live every day as if there last. When the raccoons transformed the lands(an illusion) the humans make parks and some area where animals can live.
Pom Poko(Raccoon Wars) is a funny but very sad movie which tries to tell us humans how we affect our world and wild life. Parents before you let your kids watch; the artist does draw the animals natural with there genitals, even some jokes are used with them. This is a great Miyazaki film and I definitely would add this to your collection.
