Overview
Distinct Administrative Region
Western Tokyo, commonly referred to as the Tama area, constitutes a significant geographical and administrative division within the broader Tokyo Metropolis. Unlike the eastern sector, which is comprised of 23 special wards, the Tama area is characterized by its 30 ordinary municipalities. These include a substantial number of cities, alongside towns and a single village, presenting a diverse urban and suburban landscape.
Historical Context
Prior to its incorporation into Tokyo Prefecture in 1893, the Tama area was historically part of Kanagawa Prefecture. This region, then often referred to as "San-Tama" (referring to West, North, and South Tama counties), has a distinct administrative lineage that predates its current status within the metropolis. Its integration into Tokyo marked a significant shift in its governance and development trajectory.
Geographical Scope
The Tama area encompasses a wide range of municipalities, from densely populated urban centers to more suburban and even rural environments, particularly in the westernmost Nishitama District. This contrasts sharply with the highly urbanized core of the eastern special wards. The region's geography is varied, contributing to its unique character within the vast expanse of the Tokyo Metropolis.

Historical Evolution
Ancient Administrative Roots
During the Ritsuryล period, the area now known as Western Tokyo was an integral part of Musashi Province. Key administrative and religious centers were established within this region. The provincial capital was situated in Fuchลซ, the provincial temple (kokubunji) was located in what is now Kokubunji city, and the principal shrine (ichinomiya) was found in Tama.
District Reorganization
Historically, the Tama area was divided into three districts: Nishi-Tama (West Tama), Minami-Tama (South Tama), and Kita-Tama (North Tama). These districts encompassed various cities, towns, and villages. Over time, administrative boundaries evolved, leading to the dissolution of Minami-Tama and Kita-Tama districts as their constituent municipalities were fully established or reorganized into cities.
