Sumida River Cruise Pt 7 - Flood Gates
The section at the top could serve a few functions. I would imagine it would house electronics or hydraulics to lower and raise the gates, access for maintenance, an observation/ viewing point, and maybe even a walkway over the water from one side to the other for local residences.
I am surmising of course, but I don't think I am too far from the truth.
