There were three stories, all pretty good. “The Old Man Who Made the Trees Blossom” was a little different version. Shiro the magical dog could talk, but he still got whacked by the bad neighbor (offscreen). There’s a lot of focus on Buddhist/Shinto prayer for the dead, too, so it’s not a minor part of the story. Also poop was involved. (A lot of Japanese folktales involve poop in the authentic versions. Earthy humor thing.)
About 8 minutes in, there was “The Man Who Bought Dreams.” It emphasized honesty as much as cleverness, and it was a nice peaceful story. Very funny visualization of dreaming, though!
Finally there was “The Rat Sutra,” which is a funny story of a conman outsmarting himself. There are some explanations, but it’s heavily, heavily Buddhist. Buddhist like the Pope is Catholic.
Adults will definitely enjoy these fairy tales and folktales. The animation style is fun and cute, and you’ll learn a lot about Japanese culture.
Kids probably would like this too, but it’s subtitled, so you’ll have to explain it to kids who are too young to read. (Possibly by telling your own version of the story, which is entirely true to all folktale traditions.)
Also, there’s probably no way on earth you’re going to get out of watching this particular episode without a big religious discussion, unless you’re Buddhist or something. Kids differ about this, though. I read a lot of mythology and stuff from when I was a tiny kid, but it didn’t have any power to convince me; I just thought it was more interesting stories and folkways. Other kids, not so much. You parents know your own kids best.
