On this bright sunny Saturday morning, I visited all nine (!) bridges connecting Shinkawa to the rest of Tokyo. It’s a good excuse for an exercise and is also a good way of exploring the neighborhood.
I see Shinkawa as a small “island” surrounded by bridges and rivers including the huge Sumida River to the east. I’ve heard people call it the Venice of Tokyo because of all these water channels.
It is so small, there are no train/subway stations in Shinkawa. The nearest subway stations would be Kayabatcho and Hatchobori, which are not that far away anyways.
