The station is a key one for several routes. There are, actually, two stations with this name – Tokyo Metro and Tobu Line. Check in advance, which exit you need, as there are plenty. To get there, walk to Daimno Station and ride Ginza Line to Asukasa. Here admire a beautiful corner building of Tobu Line Station, its art-nouveau style will never make you think it is a railway terminal. To buy transport cards, go to the information desk on the first floor. From here you can go to Nikko or explore inner Tokyo. You can also take a water bus or exit to the Sumida River.
