Sanjō is located in an inland region of north-central Niigata Prefecture. It is about 2 hours from Tokyo via the Jōetsu Shinkansen or 4 hours on the Kan-Etsu Expressway and Hokuriku Expressway. The Shinano River flows through the west of it from south to north and the Igarashi River flows through the centre of the urbanised area.
The area of present-day Sanjō was part of ancient Echigo Province. The modern town of Sanjō was created with the establishment of the municipalities system on April 1, 1889. It was raised to city status on January 1, 1934. Heavy rain causes extensive flooding in 1961 and in 2004. On May 1, 2005 the town of Sakae, and the village of Shitada (both from Minamikanbara District) were merged into Sanjō.
Sanjō has 25 public elementary schools and nine public middle schools. There are four public high schools, and also one special education school.
