In Japan, the distribution of raccoons (Procyon lotor) is expanding and management measures vary by region. Although adaptive management based on current assessments is crucial for the management of invasive species, the assessment of current raccoon management measures is insufficient, and national trends remain unclear. Therefore, this study analyzed the status of raccoon control plans, their initiators, and their content (including objectives and monitoring items) to understand the nationwide situation of raccoon control. Results from the analysis of 303 raccoon control plans collected nationwide from March to June 2022 suggested insufficient progress in control efforts in areas of expanded distribution and low population density. Furthermore, the plans formulated by prefectures tended to include more monitoring items and had a higher rate of information disclosure than those formulated by municipalities. This finding suggests the effectiveness of prefectures in undertaking monitoring activities. In addition, no significant differences were detected in the objectives and monitoring items between the responsible departments.
