It is located north of Wakasu, east of Tatsumi, south of Yumenoshima, and west of the Arakawa River.
The name "Shinkiba" means "New Lumberyard", and is taken from the area's historical importance in the lumber industry.
Kiba had been the main centre of the lumber industry in Tokyo since 1657, when the Tokugawa shogunate moved it there after a major fire.
In the 1970s Kiba was rapidly being developed, so the lumber businesses were relocated to reclaimed land named Shin-Kiba.
