Chuuzumou is a charming short film about mice participating in sumo wrestling. The viewpoint character is a grumpy old man living with his grumpy old wife on their mountainside farm, who discovers the athletes living in their home and decides that he's going to help them achieve their dreams. It is utterly delightful and minus a few short lines of dialogue told entirely visually; if you go to the Ghibli museum and don't watch this film if it's on display, you are only cheating yourself. It is simple, expressive, suitable for everyone, and the sumo is accurately portrayed (insofar as there ain't no rule saying amouse can't wrestle). I only regret that there wasn't a large sumo mouse plush on sale in the gift shop.
