Water & Greenery Corridor (Mizu-to-Midori-no-Kairo) is a semi-urban, hiking trail in the northwestern part of Ichikawa fronting the border with Tokyo along Edogawa River.

This part of Ichikawa is dotted with patches, hills, and slithers of small forests, parks, and ponds. This "Corridor" links all this greenery and bodies of water to help protect and preserve the flora and fauna in a coordinated effort by local environmental groups.
