This study focuses on the Riverside Park (now called Kema Sakuranomiya Park) on the former Yodo River (the Okawa River) in Osaka City, and clarifies the origin and development of park planning, the process of project decision and park formation, and the factors of its realization, based on the analysis of several primary historical documents, including an exhaustive survey of newspaper articles over 48 years. The following is a summary of the findings of this study. 1) The original concept of Riverside Park was formulated under the Sadakichi Tsuruhara municipal administration during the Meiji period. 2) The reclaimed land created by the Yodo River downstream improvement project was used for parkland, and Sakuranomiya Park was born as Japan’s first Riverside Park. 3) Before World War II, park planning was considered as part of the Park System, and Riverside Park planning was decided as the postwar reconstruction city planning. 4) After WWII, land-use change and the use of funds from the Meiji centennial anniversary project led to the development of parks, and Riverside Park in the Okawa River was realized. 5) The realization of the Riverside Park was influenced by the inheritance of an urban image that emphasized the beauty of the Riverside of the Okawa River.
