Otamaya Bridge, Concrete bridge in Aoba-ku, Japan.

Otamaya Bridge is a concrete bridge with white Japanese-style ornamentation over the Hirose River, linking Otamaya-shita and Yonegabukuro in Aoba-ku, Sendai. It is 60.6 meters long and 10.1 meters wide. Below it, the river narrows but has its deepest bed, called Genbei-buchi, with a vertical cliff on the east bank and a sandy shore on the west.

A wooden suspension bridge originally stood here in 1916, connecting the two city quarters. The current concrete structure was built in 1935 to improve the transportation link between the districts.

The bridge takes its name from the nearby Zuihoden Mausoleum, which houses members of the Date clan. This historical connection shapes how local people view and relate to this crossing.

The bridge carries the city road linking Otamaya-shita and Yonegabukuro, and the two-lane roads joining it at either end are narrow. From the city centre you must cross the Hirose via either Hyōjōgawara Bridge or Otamaya Bridge. The river here, Genbei-buchi, is the deepest stretch of the Hirose, with a vertical cliff on the east bank and a sandy bank on the west.

The stretch of the Hirose River beneath the bridge, though narrow, has the deepest bed on the whole river and is known as Genbei-buchi, Genbei's pool. The east bank drops as a vertical cliff while the west side is a sandy shore. The bridge itself is 60.6 metres long and 10.1 metres wide.
