Hatakeyama clan
The area around Anamizu was part of ancient Noto Province. During the Sengoku Period (1467–1568), the area was contested between the Hatakeyama clan, Uesugi clan and Maeda clan, with the area becoming part of Kaga Domain under the Edo period Tokugawa shogunate. Following the Meiji restoration, the area was organised into Fugeshi District, Ishikawa. The village of Anamizu was established on April 1, 1889 with the establishment of the modern municipalities system. It was raised to town status on August 10, 1903. Anamizu annexed the neighbouring villages of Shimazaki and Tobo on April 1, 1908; the villages of Kabuto and Sumiyoshi on March 31, 1954; and the village of Morohashi on March 10, 1955.
