Shiojiri is located in former Shinano Province, and as its name implies, was traditionally a centre for salt production. During the Edo period, Narai-juku, Shiojiri-shuku and Seba-juku developed as post stations on the Nakasendō highway connecting Edo with Kyoto. The village of Shiojiri was established with the creation of the modern municipalities system on April 1, 1889. It was elevated to town status on April 1, 1927. Shiojiri annexed the villages of Kataoka, Hirooka, Souga and Chikumazi on April 1, 1959 and was elevated to city status. Shiojiri lost Kitauchida hamlet and Gakenoyu hamlet (both in Kataoka ward) in 1960 and 1961 to Matsumoto city due to border adjustments. On June 28, 1961, Shiojiri absorbed the village of Seba and the village of Narakawa on April 1, 2005.


Shiojiri has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 18 members. Toshiyuki Oguchi is serving as the current mayor of Shiojiri. His first win in the mayor election was in 2002.


The economy of Shiojiri is largely agricultural, with grapes, apples, pears, and wine production as major components. The manufacturing sector includes precision instrumentation.[4]
