Nishio (西尾市 Nishio-shi) is a city located in Aichi Prefecture, in the Chūbu region of Japan. It is a regional commercial and manufacturing center and the country's leading producer of powdered green tea.

As of May 2015, the city had an estimated population of 166,278 of which some 5,800 are foreign residents. The total area was 160.22 square kilometres (61.86 sq mi) and the population density is 1,030 persons per km².


The Mikawa area has been inhabited since prehistoric times, as attested by finds of pottery shards from the Jōmon period and the megalithic Kofun tomb in Kira, the oldest in the Mikawa Province. The fertile plains along the Yahagi River have been used for rice-farming as well as the production of tea and cotton since ancient times. Shell mounds dating to the late stone age and found in what is today the town center also point to fish and seafood as important early local produce. In Hazu, a shrine from the Nara period is evidence of an early cultural connection to the Japanese capital at the time.

During the 15th century Sengoku period, Nishio was the home territory for the Sakai clan, based at Nishio Castle. The area eventually came under the control of the Tokugawa clan, and during the Edo period, most of the area was ruled as the Nishio Domain, a minor fudai feudal domain of the Tokugawa shogunate. The area prospered as a fishing port, and due to its location on the Tōkaidō highway connecting Edo with Kyoto, although the town itself suffered heavy damage due to a tsunami in the 1707 Hōei earthquake.

Early in the Meiji period, Nishio was proclaimed a village in Hazu District in 1871. Following the 1891 Mino-Owari earthquake, a tsunami killed over 60 people. Nishio was elevated to town status on May 1, 1906. The town suffered damage in the 1944 Tōnankai earthquake, which killed 32 people, and the 1945 Mikawa earthquake, which killed 765.

After the end of the second World War, Nishio attracted many workers from the rural south of Japan and its population increased. In 1953, Nishio became a city with the annexation of neighboring Heisaka and Terazu towns and Fukuchi and Muroba villages; followed by Miwa and Meiji villages in 1955. In 1959, Typhoon Vera caused considerable damage to the area, with 20 people killed.

On April 1, 2011, the towns of Hazu, Isshiki and Kira (all from Hazu District) were merged into Nishio. Hazu District was dissolved as a result of this merger.


Nishio is situated on the northern coast of Mikawa Bay on the Pacific Ocean in southern Aichi Prefecture. The city lies along the eastern bank of the Yahagi River. Sheltered by Chita Peninsula and Atsumi Peninsula, the local climate is mild. Parts of the city lie within the borders of the Mikawa Wan Quasi-National Park
