Watch Dive in Tokyo Season 1 Episode 3 Online

This time, we investigate Kandagawa, or the Kanda River. James Farrer (Professor, Sophia University) tracks the river across the city to find out how it became the way it is now. Along the way, he encounters old dye workshops, a giant underground reservoir, and a shogun's construction project from 400 years ago. The river has been involved in everything from providing drinking water, to flood protection, to providing security for a castle. Join us as we unravel the secret story of Kandagawa.
