During the Edo period, all of Izu Province was tenryō territory under direct control of the Tokugawa shogunate, and the area now comprising Itō was occupied by 15 small farming and fishing hamlets. It was in this area that the Tokugawa shogunate ordered Englishman William Adams to construct Japan's first western-style sailing vessels in 1604. The first ship, an 80-ton vessel, was used for surveying work, and the second ship, the 120-ton San Buena Ventura was sailed to Mexico. The period is commemorated in Itō by a street named after Adams (Anjinmiuradori). The area was reorganized into four villages (Tsushima, Itō, Komuro and Usami) within Kamo District with the establishment of the modern municipalities system in the early Meiji period in 1889, and was transferred to Tagata District in 1896. On January 1, 1906 the village of Itō was elevated to town status. It annexed neighboring Komuro Village on August 10, 1947 and became the city of Itō. In 1950 Itō was proclaimed an "International Tourism and Cultural City" by the central government. It further expanded through annexation of neighboring Tsushima and Usami villages on April 1, 1955.


Itō has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 20 members. The city contributes one member to the Shizuoka Prefectural Assembly.


Itō is one of the well known hot spring resort towns near the greater Tokyo metropolis, and tourism is the mainstay of the economy. Commercial fishing and the production of stockfish form a secondary economy.


Itō has ten public elementary schools and five public middle schools operated by the city government and two public high schools operated by the Shizuoka Prefectural Board of Education. In addition, the prefecture also operates one special education school for the disabled.
