A view now across the Sumida River to construction happening. I found the shadows interesting on the buildings, and have come to the conclusion it is painted that way, or has something to do with the construction of the building. It appears to have sections protruding outwards, forming the curved line. It can be plainly seen on the sides of the building too, making me think it is construction rather than paint. I wonder if this is just a design feature of if there is some functional purpose?
