  In July 2012, a joint multi-party bill was submitted to the Diet that would allow for implementation of the Osaka Metropolis plan as pursued by the mayor of Osaka city, the governor of Osaka and their party. If implemented, Osaka City, neighboring Sakai City and possibly other surrounding municipalities would dissolve and be reorganized as four special wards of Osaka prefecture – similar to former Tokyo City 's successor wards within Tokyo prefecture. Special wards are municipal-level administrative units that leave some otherwise municipal administrative responsibilities and revenues to the prefectural administration.
  
  In October 2018, the city of Osaka officially ended its sister city relationship with San Francisco in the United States after the latter permitted a monument memorializing "comfort women" to remain on a city-owned property, circulating in the process a 10-page, 3,800-word letter in English addressed to San Francisco mayor London Breed.
  
  On November 1, 2020, a second referendum to merge Osaka's 24 wards into 4 semi-autonomous wards was narrowly voted down. There were 692,996 (50.6%) votes against and 675,829 (49.4%) votes supported it. Osaka mayor and Osaka Ishin co-leader Ichiro Matsui said he would resign when his term ended in 2023.
