The river branches off from the Arakawa River in Iwabuchi (Kita Ward) and flows into Tokyo Bay. Along its course, the Sumida River passes through seven Tokyo wards, including Kita, Adachi, Arakawa, Sumida, Taito, Koto, and Chuo.
In the Meiji era, the original path of the Sumida River was part of the Arakawa River. The river was manually diverted to prevent flooding near the Imperial Palace in Chiyoda. The Sumida River has also inspired art, literature, kabuki theater, and poetry, making it an integral part of Tokyo’s culture and history.
