The forms いわき, 石城, 岩城, and 磐城 are all ways of writing "Iwaki," which means "rocky castle". Today, いわき is the most common written form.
Iwaki's origin dates back to 708 AD, during the Nara period. The Yamato government constructed a barrier in Iwaki against possible invasion by the Emishi, a Japanese people from the north. When the Taika Reform was established in AD 645, the central government formed "Iwaki district (磐城郡)" in the northern part of the present city and "Kikuta district (菊多郡)" in the southern part. In 653, the Iwaki district incorporated part of Taga Province and became Iwaki district(岩城評). In 718, Iwaki Province was formed, which was composed of five districts with Mutsu Province: Iwaki (岩城), Shineha, Namekata, Uta, Watari and Kikuta which was given from Hitachi Province. Shineha was the present Naraha. Namekata and Uta were the present Soma. Watari was the present Watari, Miyagi. The area of the present Iwaki City was composed of Kikuta and Iwaki (岩城 or 磐城).
In the late 11th century, the Iwaki clan (岩城氏) of Hitachi Province invaded Iwaki district (磐城郡) and divided it into four districts of Yoshima, Iwasaki, Iwaki, Naraha. The clan settled in the Iwaki district. In 1189, Minamoto no Yoritomo appointed Iwaki Taro Kiyotaka (岩城太郎清隆) to jito of Yoshima.
In 1532, the Battle of Kidogawa was fought. In 1590, Toyotomi Hideyoshi came in Tohoku region and demanded sword hunt and kenchi. In 1600, Iwaki Sadataka (岩城貞隆) did not fight on Ieyasu's side in the Battle of Sekigahara. As a result, the Iwaki clan was ousted and Torii Tadamasa was appointed as the lord of Iwakitaira Domain by Tokugawa Ieyasu. Ieyasu put Tadamasa of his Fudai in fear of Date Masamune of the Sendai Domain. The domain had an income of about 100,000 koku.
In 1603 Edo period, Torii Tadamasa started to construct Iwakitaira Castle in Taira. Izumi Domain (1634) and Yunagaya Domain (1670) were placed, following Kubota Domain (1622) and Tanagura Domain (1634). In 1684, Kubota han's territory was confiscated. In 1860, Ando Nobumasa of Iwakitaira han was appointed as a Roju of Tokugawa shogunate. In 1862, he was wounded near the sakashitamon-gate in Edo Castle.
In the Boshin War, the hans in Iwaki lost and were controlled by the new government (新政府). In 1871, Abolition of the han system was practiced and the hans in Iwaki became a prefecture: Iwakitaira Prefecture, Yunagaya Prefecture and Izumi Prefecture. These prefectures were incorporated to Iwamae (Iwasaki) Prefecture (磐前県) and to the current Fukushima Prefecture (1876). In 1896, Iwaki Bank and Taira Bank were established.
In 1897, Nihon Tetsudo filled in the inner moat of Iwakidaira Castle and made Taira Station. Jōban coalfield, which was the biggest coalfield in Honshū and the nearest from the Japanese capital Tokyo, was started to exploit it under the Fukoku kyōhei policy. After which Iwaki developed into an industrial city for the exploitation of the coalfield. The Jōban Line was made for the haulage of the coal. Iwaki's fishery, forestry and agricultural sectors also developed from this time. After World War II, the Jōban coalfield was closed. The same natural hot springs that were troublesome to the coal miners were put to good use and a hot springs resort was developed Spa Resort Hawaiians.
The present city was incorporated on October 1, 1966, with the merger of 14 municipalities (5 cities, 4 towns and 5 villages). The cities were Taira (平), Uchigō (内郷), Iwaki (磐城), Nakoso (勿来), and Jōban (常磐); the towns, Yotsukura, (四倉) Tōno (遠野), Ogawa (小川) and Hisanohama (久之浜); and the five villages were Yoshima (好間), Miwa (三和), Tabito (田人), Kawamae (川前) and Ōhisa (大久). Taira was chosen as the location for City Hall and other administrative offices and continues to function as the centre of Iwaki. This stem from that Torii clan's castle town was Taira. In April 1979, an "Iwaki Number" as an automobile number plate was introduced.
On April 1, 1999, the city was designated a core city.
