Planned/Future Mergers

There are no planned mergers in Aichi Prefecture as of April 2024, but there are some concepts and failed attempts.

The town of Higashiura attempted to be elevated to city status, but failed due to data padding boosting the population count to meet requirements being exposed.
The towns of Minamichita and Mihama attempted to merge into the city of Minami-Centrair, but failed due to heavy backlash from the residents, due to the fact that Chubu Centrair International Airport is located in Tokoname, and that the name was far different from the names that the local residents proposed.^[2] ^[3]
A referendum was held if the town of Agui should merge into the city of Handa, but failed due to low support from locals.
