🏞 Origin of the Name & Geographic Background
The name “Edogawa” comes from the Edo River, the major Class-A river flowing along the district’s eastern edge.
The Edo River was shaped during Tokugawa Ieyasu’s major flood-control project (the “Tone River Diversion”) in the early Edo period.
The current river course is partially artificial, created by diverting the original “Taito-gawa,” which helped develop river ports and post towns.
Today the area consists of both the modern main channel (floodway) and the Old Edo River, which forms the border with Chiba Prefecture and flows into Tokyo Bay.
Edogawa City is a district where water and history have always been deeply intertwined.
