In April, an explosive device was thrown near Prime Minister Kishida, who was visiting Wakayama City to support the election. The National Police Agency compiled a report analyzing and evaluating the security measures at that time.

It concluded that the incident was allowed to occur because there was no in-depth consultation between the police and the organizers of the speech and the failure to include effective safety measures in the protection plan. It will review its response to thorough protection and security, such as lobbying the organizers.
