The area of present-day Namerikawa was part of ancient Etchū Province. During the Heian period, much of the area was part of shōen controlled by Yasaka Shrine in Kyoto. During the Edo period it was part of the territory controlled by the Maeda clan of Kaga Domain. The town of Namerkawa was created within Nakaniikawa District, Toyama with the establishment of the modern municipalities system on April 1, 1889. On November 1, 1953, Namerigawa merged with the neighboring villages of Nakakazumi, Higashikazumi, Nishikazumi, Kitakazumi, Hamakazumi and Hayatsukikazumi. It was raised to city status on March 1, 1954.
Once a rural town in the overlooking Toyama bay, then prospering as inn town on the Hokuriku Kaidō, Namerikawa has developed as an industrial city and commercial center, and is increasingly a bedroom community for nearby Uozu.
Namekawa has seven public elementary schools and two public junior high schools operated by the town government, and one public high school operated by the Toyama Prefectural Board of Education.
