地方自治法
The title "chōkan" for the governor actually remained in place until 1947 when the Constitution and the Local Autonomy Law made Tokyo equal with other prefectures again and gave the residents of former Tokyo City (almost) the same rights as in other municipalities with the introduction of special wards. The first gubernatorial election, held in April 1947 as part of the 1st unified elections, was still held as "Tōkyō-to chōkan senkyo", and the first elected governor (who had also been the penultimate appointed governor from 1946 to 1947) initially still took office as "chōkan", but became "chiji" in May 1947.
