The area of Inzai has been inhabited since the Japanese Paleolithic period, with some stone tools having been found in Kikaribyo that were used by people during that time. During the Edo period, the village of Kioroshi developed as a port at the bank of Tone River.

After the Meiji Restoration, on April 1, 1889, the town of Kioroshi, and the villages of Omori, Taisha, Funoho, Rokugo, Munakata, Hongo and Eiji were founded with the establishment of the modern municipalities system. The Meiji Era is also the golden age for steam ships in Tone River sailing from Tokyo to Chōshi. Taisha was raised to town status on March 1, 1913 and renamed Omori Town. In 1942, a pilot training center was built in Sofuke. This place was hit by Allied air raids in World War II. After the war the training center was abandoned.

On December 1, 1954, the town of Inzai was founded through the merger of the towns of Kioroshi and Taisha, and the villages of Eiji and Funaho. At the time the population was about 11,000.

The development of the Chiba New Town project and the Hokusō Line considerably boosted the development of Inzai from the mid-1980s. Inzai was elevated to city status on April 1, 1996.

On March 23, 2010, Inzai absorbed the villages of Inba and Motono (both from Inba District) to create the new and expanded city of Inzai.

Inzai has a mayor-council form of government with a directly elected mayor and a unicameral city council of 22 members. Inzai, together with the neighboring town of Sakae, contributes two members to the Chiba Prefectural Assembly. In terms of national politics, the city is part of Chiba 13th district of the lower house of the Diet of Japan.

Inzai has mixed economy dominated by large shopping centers and industrial parks. Its location and good transportation connections between Tokyo and Narita International Airport have led to numerous logistics companies establishing warehouse and distribution centers in the city. The development of Chiba New Town has also greatly increased the number of commuter residents, with over 24% of the working population traveling to Tokyo daily.
