2020 Osaka Metropolis Plan referendum
A referendum on the implementation of the Osaka Metropolis Plan was held in Osaka on 1 November 2020. In the event of a "yes" vote, the wards in Osaka City would be reorganized into special wards similar to those in Tokyo. The proposal was defeated by a slim margin of 17,167 votes.
A previous referendum on the issue in 2015 was defeated by a similar margin. Each ward's choice exactly mirrored 2015.
