A sad but ultimately uplifting story of a kappa whose father is killed by a samurai wanting to convert their swamp to farmland, and the boy who much later discovers his son, "Coo" (Japanese Kû, evidently) as a fossil, in modern Japan. Despite numerous difficulties, mostly from suspicious outsiders, spirit and human are reconciled, at least for this family. Oh, and Coo loves to sumo wrestle, despite his small size. Not by Miyazaki, but of Ghibli quality.

I watched this movie when I was a kid this movie is very emotional movie movie is for all ages this movie very underrated this is a story of a kappa coo and koichi and his family. Movie is 2 hour 18 Minutes.

"Summer Days with Coo" is full of realism and one of the finest animated works which won the animation of the year.You will see in this beautiful movie how human beings who live in concrete jungle forgot sincerity to others. Coo may look like an alien to you but he and his summer days with one kind human family will remind you of your lost memories and bittersweet nostalgia. "Summer Days with Coo" even includes several social problems such as overreaction of mass media, bullying and invisible violence in our society.

Overall, "Summer Days with Coo" is very good movie , not a kind of only critically acclaimed movie.I recommend this to all the people who want serious and sincere movie works but this could be excellent for education.
