To the north of Ryōgoku Bridge on the east bank of the Sumida River is a spot called Senbongui. Meaning literally “a thousand poles or stakes,” Senbongui was marked with posts, which were driven into this section of the embankment to halt erosion. There are strong currents at this point in the river, in part because it is where salt tidewaters mix with freshwater from the north. These waters were known for excellent catches of fish.
Kiyochika followed the master Hiroshige in selecting this site as an important one in the lexicon of notable places in Edo/Tokyo. Today, concrete walls control the river and an express highway runs above it. The only markers for this site are a plaque, a few mural paintings, and a symbolic clustering of stakes.
