Above Kanda River we see a flume, through which Kanda service water flows. Between the bridge girders we can see in the distance an aqueduct. This was one of the famous scenes of Edo. During the rule of the second shogun Hidetada, Kanda River was formed to function as both a means of flood prevention and an outer moat to Edo Castle and it is linked with Sumida River. The canyon pictured here was created during this time.
