Tokyo is promoting the development of small and medium-sized rivers and streams to protect the lives and livelihoods of Tokyo residents from flood damage and to create moist and peaceful waterfronts.
We have received approval for urban planning work for the following section of the Shakujii River. In response, we will begin work on river improvement projects.
Going forward, we will proceed with design and other preparations for construction on the following sections.

1　About the Shakujii River

The Shakujii River is a first-class river that originates in Kodaira City in the central-northern part of Tokyo, flows almost in a straight line east through northern Tokyo, and joins the Sumida River in Kita Ward. Its drainage area is 73.1 square kilometers, and its length is 25.2 kilometers.

2　Overview of the project

In order to safely drain floodwaters caused by rainfall of 50 millimeters per hour, we will improve the river channel by widening the river width, etc., in order to reduce flood damage.

3　Business location

The new section to be worked on is approximately 390 meters from Sekimachi Kita 2-chome, Nerima Ward (upstream of Honryuji Bridge) to Sekimachi Kita 3-chome (downstream of Benten Bridge). *Attached guide map (PDF: 664KB)

This project is an initiative to promote the “Tokyo 2050 Strategy.”
