Kagurazaka (神楽坂) is a neighbourhood in Tokyo, near Iidabashi Station. It has a shopping street at its center, lined by numerous cafés and restaurants. It is served by Tokyo Metro Tozai Line and Toei Oedo Line. The main road of Kagurazaka was once at the outer edge of Edo Castle, opposite the Ushigome bridge over the castle moat, and has always been busy because of this privileged location. In the early 20th century, the area was renowned for its numerous geisha houses, of which several remain today. Currently, Kagurazaka is experiencing a popularity boom due to its traditional, sophisticated atmosphere on the edge of modern Shinjuku ward and proximity to Waseda University.
