The is the prefectural parliament of Tokyo Metropolis.
Its 127 members are elected every four years in 42 districts by single non-transferable vote. 23 electoral districts equal the special wards, another 18 districts are made up by the cities, towns and villages in the Western part of the prefecture, one district consists of the outlying islands (Ogasawara and Izu Islands).
The assembly is responsible for enacting and amending prefectural ordinances, approving the budget (5.7 billion yen in fiscal 2007) and voting on important administrative appointments made by the governor including the vice governors.
Due to the special nature of the Tokyo Metropolis compared to other prefectures, the Tokyo Metropolitan Assembly has certain powers that would usually fall into the responsibilities of municipal parliaments. This is to ensure efficient and unified urban administration for the 23 special wards that cover the former Tokyo City and comprise the urban core of the Greater Tokyo Area.

Electoral districts Most electoral districts correspond to current municipalities, but several districts correspond to former counties (the counties, abolished as administrative unit in 1921, had initially by definition served as electoral districts for prefectural assemblies in the Empire), namely the West Tama (Nishi-Tama), North Tama (Kita-Tama) and South Tama (Minami-Tama) counties. The towns and villages on the islands have never been subordinate to counties, but to four subprefectures that together form the islands electoral district.

Incidents
Heckling incident On June 18, 2014, an assemblywoman, Ayaka Shiomura, was heckled in the Tokyo Metropolitan Assembly meeting when she asked questions about how to save women who have difficulty in pregnancy and childbirth. The comments were and . When assembly member was asked whether he was one of the hecklers, he denied heckling Shiomura. After the LDP identified Suzuki as the heckler on June 23, he came forward and made a formal, public apology, admitting he was one of the people who heckled Shiomura. Suzuki claimed responsibility for the first comment, but it was not clear who stated the latter. Yōichi Masuzoe, the Governor of Tokyo Metropolis, and fellow assembly member, apparently took part in the heckling. Other hecklers never came forward. On June 25, the assembly passed a resolution, aiming to restore trust, and settle the issue.
Reactions Some believe that heckling can "give humor" and make discussion smooth and thus view heckling positively. Morita Minoru, a Japanese political commentator, pointed out that the number of "vulgar heckles" has increased. Some argue sexism is a major reason. For example, Tabojin Toshio, who oversaw for the latest Tokyo Metropolitan Assembly election, said that he did not understand why this is considered sexism (2014).
Several members of Abe's cabinet criticized the incident - then-chief cabinet secretary Yoshihide Suga encouraged the Assembly to "clean up its act", while health minister Norihisa Tamura and Minister of State for the Declining Birthrate Masako Mori respectively described the comments as "deeply disrespectful to women" and "totally unacceptable". The Guardian, Reuters, and the Wall Street Journal reported on and analyzed the incident.
