## Location

JR East's Ochanomizu station lies south of the Kanda River in Chiyoda ward. During the Edo period, the Kanda River was rerouted to pass through Ochanomizu, which was otherwise a highland between two valleys. Hijiribashi (聖橋, Hijiri Bridge) crosses over the river near a station exit. The subway Marunouchi Line makes a short above-ground appearance as it passes over the river. Holy Resurrection Cathedral (Nicholai-dō) is easily accessible from the Hijiribashi Exit of this station. The Ochanomizu neighborhood is known for its many guitar and instrument shops.
The Tokyo Metro station is located in Bunkyō Ward, separate from the JR East station, and is served by the Marunouchi Line. The area is also served by the Chiyoda Line at Shin-Ochanomizu, which is connected to Ogawamachi on the Shinjuku Line.

The JR East portion of the station has two island platforms serving four tracks, forming a Cross-platform interchange. Tracks 1 and 4 (the outer tracks) serve trains on the Chūō Line whilst tracks 2 and 3 are used by trains on the Chūō-Sōbu Line.
