Itō (伊東市, Itō-shi) is a city located on the eastern shore of the Izu Peninsula in Shizuoka Prefecture, Japan.

Itō is located in eastern Shizuoka Prefecture, on the northeast corner of Izu Peninsula, facing Sagami Bay on the Pacific Ocean.

[3] 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.

Itō has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 20 members.

Itō is one of the well known hot spring resort towns near the greater Tokyo metropolis, one of the best three in all of Japan, thus tourism is the mainstay of the economy.
