Sumida River Cruise Pt 7 - Flood Gates

More flood gates, or whatever they are. I am fairly certain they are flood gates. This time there are two side by side, and if we look closely they are raised to the same level as the brick levee at the side.

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.

Flood gates? Maybe. I am unsure of the purpose of these gates, but I figure they would be lowered in times of storms, high tides, tidal surges and typhoons. I would imagine they would stop all the tide surges going up this small channel of water and possible causing damage to buildings, homes, businesses etc.
