In 1888, the central government created the legal framework for the current system of cities (shi) that granted some basic local autonomy rights – with some similarities to Prussia's system of local self-government as Meiji government advisor Albert Mosse heavily influenced the organization of local government. But under a special imperial regulation, Tokyo City, like Kyoto City and Osaka City, initially did not maintain a separate mayor; instead, the (appointed) governor of Tokyo Prefecture served as mayor of Tokyo City. The Tokyo city council/assembly (Tōkyō-shikai) was first elected in May 1889. Each ward also retained its own assembly. City and prefectural government were separated in 1898. , and the government began to appoint a separate mayor of Tokyo City in 1898, but retained ward-level legislation, which continues to this day in the special ward system. From 1926, the mayor was elected by the elected city council/assembly from its own ranks. The city hall of Tokyo was located in the Yūrakuchō district, on a site now occupied by the Tokyo International Forum.
