which makes the city one of the youngest major cities in Japan. Governance Sendai's political system is similar to other cities in Japan, because the Local Autonomy Law makes all municipalities uniform in terms of organization and power. However, Sendai is a designated city, so it has the same jurisdiction as prefectures in some areas. Sendai has a mayor-council form of government with a directly elected mayor and a unicameral city legislature. The Sendai City Assembly members are elected from 5 elective districts, which correspond to the city's 5 wards. The number of assembly members allocated to each ward is based upon population. As of May 2005, the city has 60 assembly members; 17 from Aoba Ward, 11 from Miyagino, 8 from Wakabayashi, 13 from Taihaku, and 11 from Izumi.

In terms of national politics, the city is divided between the Miyagi 1st district and the Miyagi 2nd district of the lower house of the Diet of Japan.
