Tama is located in the foothills of the Okutama Mountains of southwestern Tokyo, known as Tama Hills, which spans Tokyo and Kanagawa Prefecture. The entire region is historically referred to as Tama; therefore there are many place names scattered throughout the area with references to the name "Tama" which are not within the city limits. The Tama River marks the city's northern boundary, and Kanagawa Prefecture is to the south. Its southern half forms part of the Tama New Town project, Japan's largest residential development, constructed in the 1970s.

  • The area of present-day Tama was part of ancient Musashi Province. In the post-Meiji Restoration cadastral reform of July 22, 1878, the area became part of Minamitama District in Kanagawa Prefecture.
  • Tama Village was founded on April 1, 1889 from the merger of 11 pre-Meiji period hamlets with the establishment of the modern municipalities system.
  • Minamitama District was transferred to the administrative control of Tokyo Metropolis on April 1, 1893.
  • Tama was elevated to town status on April 1, 1964. Construction of Tama New Town began in 1966, and the first occupants started moving in 1971.
  • On November 1, 1971, Tama Town was reclassified as Tama City, dissolving Minamitama District. Tama was the last town in the former Minamitama District.


Tama has a mayor-council form of government with a directly elected mayor and a unicameral city council of 26 members. Tama, together with the city of Inagi, contributes two members to the Tokyo Metropolitan Assembly. In terms of national politics, the city is divided between Tokyo 21st district and Tokyo 23rd district of the lower house of the Diet of Japan.


In 2018, an activist named Michihito Matsuda ran for mayor in the Tama city area of Tokyo as a human proxy for an artificial intelligence program.[4] While election posters and campaign material used the term robot, and displayed stock images of a feminine android, the "AI mayor" was in fact a machine learning algorithm trained using Tama city datasets.[5] The project was backed by high-profile executives Tetsuzo Matsumoto of Softbank and Norio Murakami of Google.[6] Michihito Matsuda came third in the election, being defeated by Hiroyuki Abe.[7] Organisers claimed that the 'AI mayor' was programmed to analyze citizen petitions put forward to the city council in a more 'fair and balanced' way than human politicians.[8] In 2022, Michihito Matsuda made the campaign pledge to install THXU token into Tama city's further development as one of Government by algorithm.[9]
