Himawari Nursery School is a preschool from the film Ponyo on the Cliff by the Sea. Karen, Kumiko and Sōsuke go there. Himawari means Garden of Sunflowers.

The kindergarden is located in Tomonoura next to Lisa's workplace Himawari Service Center. Sōsuke often crawls through a hole in the fence to get to the home for the elderly. Yoshie, Noriko and Toki are always happy to see him.

At the kindergarden you can see Sosuke's House.
