There are two exits at this beauty. The West exit takes you over to the land of actually having a public restroom within the station, as well as the connection with the Toei Oedo line, which, FYI is ridiculously deep underground, so if you’re planning on making the transfer, a) give yourself some extra time to get there and b) try and ride the train on the side that will take you over near the escalator to the West exit. The East exit has a new coffee shop right outside of the turnstiles, if you’re into that. No restrooms at the East side.
