Sanuki Kodomo no Kuni is a large-scale children's park adjacent to Takamatsu Airport. Aiming to support the growth of children's minds and bodies through hands-on experiences, this establishment has a variety of indoor and outdoor facilities where children can learn while they play. Outside, there is a cycling center with unique rental bicycles shaped like dolphins and dogs available, as well as a spacious cycling route. There is also an open lawn where kids can run around freely, playground equipment, and even a retired passenger airplane on display. At the indoor facility, Waku Waku Children's Center, kids can try out space-themed science technology in the Play Zone or watch shows at the Space Theater, a brand-new planetarium that just went through a renewal in 2019. Kids can also enjoy creating a multitude of things at art workshops or try out musical instruments at music workshops. The park is also equipped with a space where infants and their guardians can play with wooden toys, ensuring that children of all ages can have a fun time.
