Ichinoseki is located inland in the south of Iwate Prefecture, a little over two hours north of Tokyo by the Tōhoku Shinkansen. A large volume of extremely stable granite rock runs beneath the city, and is the center of the site is being promoted as a suitable location for construction of the International Linear Collider (ILC).^[2]

The agricultural makeup of the city outside the centre is mostly composed of farmers, leading to an influx of Chinese and Filipino immigrants due to marriage. As a result, Ichinoseki has a varied ethnic makeup, although the newcomers still remain a small minority.

Per Japanese census data,^[6] the population of Ichinoseki peaked in the 1950s and has declined over the past 70 years. Ichinoseki has been recognized by Japan's Office for the Promotion of Regional Revitalization (Kishida Cabinet Secretariat), which promotes the development of new technologies to combat depopulation, for meeting a "high standard" of digital transformation/telework infrastructure. Related projects have been awarded over ¥80M in government grants.^[7]

The area of present-day Ichinoseki was part of ancient Mutsu Province, and has been settled since at least the Japanese Paleolithic period. The area was inhabited by the Emishi people, and came under the control of the Yamato dynasty during the early Heian period. During the Heian period, it was controlled by the Abe clan, followed by the Northern Fujiwara clan of Hiraizumi. During the Sengoku period, the area was dominated by various samurai clans before coming under the control of the Date clan during the Edo period, who ruled Sendai Domain under the Tokugawa shogunate. A portion of the present city was part of Ichinoseki Domain, a sub-domain of Sendai Domain.

The town of Ichinoseki was established within Nishiiwai District, Iwate on April 1, 1889 with the establishment of the modern municipality system. It was raised to city status on April 1, 1948 by the merger of the towns of Ichinoseki and Yamame with the villages of Mataki and Nakasato.
