On April 1, 2005, Nirayama, along with the towns of Izunagaoka and Ōhito (all from Tagata District), was merged to create the city of Izunokuni and thus it no longer exists as an independent municipality.
During the Kamakura and Muromachi period, Niirayama was the site of a castle belonging to the Hōjō clan, and the later Hōjō clan. During the Edo period, it was the location of the daikansho offices of the Tokugawa shogunate controlling Izu Province.
