From 1898 through the Second World War, mayors were nominated by the Kyoto City Assembly and appointed by the Minister of Home Affairs. Since 1947, mayors of Kyoto have been chosen by direct election to four-year terms. As of 2022, there have been nine mayors elected using this system. While some mayors have resigned or died in office, no mayor has lost a reelection bid in the postwar period.
