"Ichinomiya" literally means "the first shrine" of a province. In case of Owari Province, this was Masumida Shrine, which dates to the Nara period and was located close to the provincial capital in what is now the city of Inazawa. Ichinomiya developed as a monzen-machi from the Heian period and was part of the holdings of Owari Domain under the Edo period Tokugawa Shogunate. In the early Meiji period, with the establishment of the modern municipalities system on April 1, 1889, the town of Ichinomiya was created within Nakashima District

Ichinomiya was raised to city status on September 1, 1921. The city annexed the neighboring villages of Haguri and Nishinari in 1940, and with an additional eight surrounding municipalities (the villages of Chiaki, Tanyo, and Kitakata, and the towns of Asai, Yamato, Akiwara, Oku and a portion of Imaise) in 1955.

On April 1, 2002, Ichinomiya was designated as a Special City, with increased local autonomy.

On April 1, 2005, the city was further expanded by absorbing the city of Bisai, and the town of Kisogawa (from Haguri District) which made it the fourth largest in Aichi Prefecture, after Nagoya, Toyota, and Toyohashi.


Ichinomiya has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 38 members. The city contributes five members to the Aichi Prefectural Assembly. In terms of national politics, the city is divided between Aichi District 9 and Aichi District 10 of the lower house of the Diet of Japan.


Traditionally noted for textiles, Ichinomiya is now a regional commercial center with a mixed economy of manufacturing and agriculture. Kanesue has its headquarters in Ichinomiya. It moved to its current headquarters in July 1976.[4] The Eisaku Noro Company, which produces colorful handcrafting and machine yarns for clothing, is also based here.
