Seya-ku (瀬谷区?) is one of the 18 wards of the city of Yokohama in Kanagawa Prefecture, Japan. As of 2010, the ward had an estimated population of 126,839 and a density of 7,390 persons per km2. The total area was 17.16 km2.
Seya Ward is located in eastern Kanagawa Prefecture, and on the northwestern borders of the city of Yokohama. The area is largely flatland, with scattered small hills.
The area around present-day Seya Ward has been inhabited continuously for thousands of years. Archaeologists have found stone tools from the Japanese Paleolithic period and ceramic shards from the Jomon period, house ruins from the Yayoi period and tombs from the Kofun period at numerous locations in the area. Under the Nara period Ritsuryō system, it became part of Kamakura District in Sagami Province. By the Kamakura period, parts of Seya were part of a shōen which supported the Shinto shrine of Tsurugaoka Hachimangū. The Kamakura-kaidō, a highway linking Kamakura with the provinces in northern Japan also passed through the area. During the Muromachi period, Seya was a contested territory between the competing Uesugi clan and Ashikaga clan until the area was seized by the Late Hōjō clan from Odawara in the late Sengoku period. After the defeat of the Hōjō at the Battle of Odawara, the territory came under the control of Tokugawa Ieyasu. It was administered as tenryō territory controlled directly by the Tokugawa shogunate, but administered through various hatamoto. The area prospered in the Edo period as a post station on the Kamakura-kaidō and Nakahara-kaidō highways connecting Edo with Kamakura and with the provinces of central Honshu. At times, Seya was administered by Totsuka-juku, Fujisawa-shuku, and towards the Bakumatsu period came under the control of the Nirayama daikansho . After the Meiji Restoration, Seya was transferred to the short-lived Nirayama Prefecture, before becoming part of the new Kanagawa Prefecture in 1868. In the cadastral reform of April 1, 1889, the area was divided into several villages under Kamakura District. During the Meiji period, the area was a center for sericulture. Seya suffered relatively little damage from the 1923 Great Kantō earthquake, with one fatality and 53 houses destroyed. The Sagami Railway Main Line connected the area with Yokohama in 1926.
