In the Edo era, this area was the important point of the water transportation.
The left side area of the Toyomi bridge(豊海橋)was a big office and base of Tokugawa navy. Tokugawa navy was called The Pirates(海賊衆).
And the opposite bank area of the Sumida river were the big ship bases and mansions of the Pirates.
I like the design of this bridge which was reconstructed in 1927 after the falling down by the biggest earthquake in 1925.
