Shinagawa (品川区, Shinagawa-ku) is a special ward in Tokyo, Japan. The Ward refers to itself as Shinagawa City in English. The Ward is home to ten embassies.
As of 1 April 2016[update], the Ward had an estimated population of 380,293 and a population density of 16,510 persons per km2. The total area is 22.84 km2.
Shinagawa is also commonly used to refer to the business district around Shinagawa Station, which is not in Shinagawa Ward. This Shinagawa is in the Takanawa and Konan neighborhoods of Minato Ward, directly north of Kita-Shinagawa.
Shinagawa Ward includes natural uplands and lowlands, as well as reclaimed land. The uplands are the eastern end of the Musashino Terrace. They include Shiba-Shirokanedai north of the Meguro River, Megurodai between the Meguro and Tachiai Rivers, and Ebaradai south of the Tachiai River.
The Ward lies on Tokyo Bay. Its neighbors on land are all special wards of Tokyo: Kōtō to the east, Minato to the north, Meguro to the west, and Ōta to the south.
Shinagawa Ward consists of five areas, each consisting of multiple districts and neighborhoods:
Most of Tokyo east of the Imperial Palace is on reclaimed land. A large proportion of the reclamation took place during the Edo period, when Shinagawa-juku was the first shukuba (post town) in the "53 Stations of the Tōkaidō" that a traveler would reach after setting out from Nihonbashi to Kyoto on the Tōkaidō. The Tokugawa shogunate maintained the Suzugamori execution grounds in Shinagawa.
Following the Meiji Restoration and the abolition of the han system, Shinagawa Prefecture was instituted in 1869. The prefectural administration was to be set up in the Ebara District, but in 1871 Shinagawa Prefecture was integrated into Tokyo Prefecture. In 1932, during the reorganisation of the municipal boundaries of Tokyo City following the 1923 Great Kantō earthquake, a smaller version of Shinagawa Ward was created. On March 15, 1947, this was merged with the neighboring Ebara Ward to create the present Shinagawa Ward.
The Ward's historic post-town function is retained today with several large hotels near the train station offering 6,000 rooms, the largest concentration in Tokyo.
The Tōkaidō Shinkansen high-speed rail line began serving Shinagawa Station in 2003.
Shinagawa is run by an assembly of 40 elected members.
