Surreal Tone-Gawa Delta 2

The Tone River was an indispensable inland water link between the capitol at Edo, and later Tokyo, to the Pacific Ocean. It carried not only local products like soy sauce from Choshi, but also products from the Tōhoku region, in order to save time and to avoid risk in the open sea. With the advent of the railway in the 19th century major shipping on the Tone quickly declined, and inland ports such as Noda, Sekiyado, now part of Noda, Nagareyama, and Sawara, now part of Katori diminished in importance. Today the river has several dams that supply water for more than 30 million inhabitants of metropolitan Tokyo and large-scale industrial areas such as the Keiyō Industrial Zone.
