Probably the most famous bridge over the Sumida River is Ryōgoku: first built in 1659, it even has its own song and was painted multiple times by the ukiyo-e master Hiroshige and by many other artists (I must also mention Hokusai).
Its name has an interesting genesis - Ryōgoku means “two provinces” - because when it was first built, it was joining Edo (on the right shore of Sumida) with Shimōsa (on the left shore). Today, the area on the left shore, famous for its Sumo stadium, bears the name of the Ryōgoku bridge.
The present day bridge, less spectacular than the original painted during the Edo period, was inaugurated in 1932, it is 164 meters long and 24 meters tall.
