神田川
JR East's Ochanomizu station lies next to the Kanda River. During the Edo period, the Kanda River was rerouted to pass through Ochanomizu, which was otherwise a highland between two valleys. Hijiribashi (聖橋, also known as Hijiri Bridge, Hijiribashi 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.
