Tatsumi (辰巳) is an area of Koto, Tokyo, Japan. It is surrounded by water on all sides, but is joined by bridges to Shiomi to the north, Shin-Kiba and Yumenoshima to the east, and Shinonome to the west. The west side is largely residential, the east largely consists of parks. It is built on reclaimed land.
