Tokyo: Japan’s capital metropolis and the political, economic, and cultural center of the country. The region’s central city anchors its employment, transport, and civic institutions.
Tokyo metropolitan area railways: The dense network of rail lines serving Tokyo and surrounding metropolitan communities. Frequent services make long-distance daily commuting across prefectural boundaries practical.

Tokyo metropolitan employment area: A functional urban area defined by commuting ties to employment centers in Tokyo and nearby prefectures. Its commuting-based boundary can differ from broader administrative definitions of the region.
Kanagawa Prefecture: A prefecture south of Tokyo, containing Yokohama, Kawasaki, and other cities in the metropolitan region. Its dense northern cities form a continuous urban corridor with Tokyo.
Shinkansen: Japan’s network of high-speed railway lines for intercity passenger travel. Its Tokyo terminals connect the metropolis to distant cities, complementing local commuter rail.
Haneda Airport: An international airport in Tokyo serving domestic and international routes. Its location and capacity support the region’s access to other Japanese cities and global destinations.
Greater Osaka: Japan’s second major metropolitan region, centered on Osaka and extending into neighboring prefectures. It provides the clearest domestic comparison with Tokyo’s larger, more dominant urban system.
Saitama Prefecture: A prefecture north of Tokyo whose southern cities are integrated into the capital’s metropolitan region. Its commuter cities extend the region northward beyond Tokyo’s borders.
Commuting: Regular travel between a place of residence and a place of work or study. Daily flows into Tokyo help define the region’s functional extent.
