Agricultural production is expected as one of prospective role in urban agricultural gardens. Increased interest in ‘safe and fresh food’ may create great demand of agricultural activity by urban residents themselves. Precedent studies reported that agricultural productions from urban gardens are not merely consumed by garden user themselves, but are sold or served for local citizens lived in near gardens. These facts indicate that sufficient amount of agricultural products could be produced from urban agricultural gardens. However, the actual amount of agricultural production from urban agricultural gardens has not been identified in precedent studies. This study aim to identify the amount of agricultural production by measuring respective harvested products having advanced two urban agricultural gardens as case studies. In this study, the district was set up within a 500m radius as the case study garden and estimated the harvested products by ratio in all vegetable consumption. The results showed that the agricultural production from ‘experience farm’ was sufficient for the annual consumed amounts at household, while allotment gardens could not be reached at the amounts. At the scale of the district in this study, more than 10% of all vegetable consumption can be covered by the production by urban residents in urban agricultural gardens.
