能登國
The area around Kahoku was mostly part of ancient Kaga Province, with a small portion of its northern area in Noto Province. The area became part Kaga Domain under the Edo period Tokugawa shogunate. Following the Meiji restoration, the area was organised into Kahoku District, Ishikawa. The villages of Takamatsu, Nanatsuka and Unoke were established with the creation of the modern municipalities system on April 1, 1889. Takamatsu was raised to town status on August 1, 1922, Nanatsuka on February 11, 1940 and Unoke on February 11, 1948. The three towns merged on March 1, 2004 to form the city of Kahoku.
