Route 1 is one of the radial routes of the Shuto Expressway system in the Tokyo area. Route 1 has two segments: a northern segment (known as the Ueno Route) connecting Chūō-ku to Taito-ku via Ueno; and a southern segment (known as the Haneda Route) connecting Minato-ku to Haneda in Ota-ku. The two segments are connected by the Inner Circular Route.
The Ueno Route is 4.4 kilometres long beginning at Edobashi Junction at the Inner Circular Route and ending at a local road National Route 4 (Showa-dori avenue) in Taito-ku. It also serves Ueno Station. There are plans to extend the Ueno Route further north to the Central Circular Route.
The Haneda Route is 13.8 kilometres long, from Hamasakibashi Junction in Minato-ku to the Haneda Exit at Kampachi-dori (Tokyo's #8 ring road) near the Haneda Airport in Ota-ku. The expressway continues as Kanagawa Route 1 (Route K1) into Yokohama.
