The area of present-day Tonami was part of ancient Etchū Province, and was part of the holdings of Kaga Domain under the Edo period Tokugawa shogunate. The town of Tonami was founded on April 1, 1952 by the merger of the town of Demachi with the villages of Gokaya, Aburaden, Shoge, Nakamura and Hayashi. The villages of Aoshima and Ogami joined two months later on June 1, 1952. The villages of Ota, Minamihannya, Higachi-Nojiri, Yanaze and Nishi-Tonami were annexed on January 15, 1954, followed by Sendan, Sendanyama, Hannya, and Higashi-Hannya on March 1. The expanded town of Tonami was raised to city status on April 1, 1954. On November 1, 2004, the town of Shōgawa (from Higashitonami District) was merged into Tonami.
