Mai Mai Shinko and the Thousand Year Magic explores the wonder of childhood through the imaginative minds of Shinko and Kiiko as they create friendships and marvel at the world around them. Set in 1950s-era rural Japan, a small group of elementary school students must rely on their imaginations and the local farmscape to pass the time. There isn't any one central conflict to string the story along, but the characters learn to make friends, express themselves, and admire their prolific ancestors who once made the land a mighty cultural center. An imagined story of an ancient princess runs parallel to the lives of the charactersas they must struggle with issues like death and abusive fathers. The story isn't a tragedy, however, as the kids must simply learn to deal with reality and see the best in things and in each other.

Mai Mai Shinko draws obvious comparison to My Neighbor Totoro, with two young female main characters, the rural Japanese setting and predictably a little sister getting lost along the way, but unlike a typical Ghibli film, Madhouse has strayed away from the fantastic, restricting it to the minds of the children. It still draws recommendations from Ghibli fans, and anyone who wants to reminisce about their energetic childhoods.
