Nomi River System（呑川系）
Nomi River is one of Tokyo’s lesser-known rivers, quietly flowing through the city’s residential neighborhoods.
It runs through areas like Ota, Meguro, Setagaya wards, not far from the bustling streets of Kamata.
The river eventually reaches its mouth near Haneda Airport, where it flows into Tokyo Bay.
Some sections of the river are open and visible, while others are covered and hidden beneath the cityscape — forming quiet walking paths that offer a more local, everyday side of Tokyo.
