Under the Ritsuryō system, the present-day ward was the southern extremity of Adachi District, Musashi Province. In 826, during the Heian period, the Nishiarai Daishi temple was founded. During the Muromachi period and into the Sengoku period, the Chiba clan held control of the region. The Great Senju Bridge was built in 1594. In the Edo period, parts were under the direct control of the Tokugawa shogunate, and parts were under the administration of Kan'ei-ji, a temple in present-day Ueno, Tokyo.
