Most residential complexes in Japan have been developed for more than 40 years now, and due to aging, a functional decline in local communities has been reported. To address this challenge, this study aims at regional exchange with a butterfly garden-on a field at Tamondai Central Park in Tarumi district, Kobe city-where children can collect insects. The garden design in the park was executed on September 19, and a total of 381 pots of flower seedlings of 13 species were planted by 32 local children and adults. A comparison of changes in citizen exchange revealed that, after the implementation of the design, the number of users increased by 1.87 times than before the implementation. This also showed that the exchange between children and older adults increased significantly; hence, it can be said that the butterfly garden had a distinct effect on the community’s redevelopment.
