Nirayama (韮山町 Nirayama-chō) was a town located in Tagata District, Shizuoka, Japan.
On April 1, 2005 Nirayama was merged with the towns of Ōhito and Izunagaoka, both from Tagata District, to form the new city of Izunokuni.
During the Kamakura and Muromachi period, Niirayama was the site of a castle belonging to the Hōjō clan, and the late Hōjō clan. During the Edo period, it was the location of the daikansho offices of the Tokugawa shogunate controlling Izu Province.
At the time of its merger, the town had an estimated population of 19,602 and a density of 566 persons per km². The total area was 34.63 km².
Famous for its strawberry crop, Nirayama sees many visitors from bigger cities (such as Tokyo) coming for seasonal picking and the picturesque views of Mount Fuji.
