As with the rest of Ashigarashimo District, the area now comprising modern Manazuru was part of Sagami Province under control of the later Hōjō clan in the Sengoku period, and part of Odawara Domain during the Edo period. During this time, it was known for high quality stones for construction. After the Meiji Restoration, Manazuru was established as a village in 1889 with the establishment of the modern municipalities system. On October 1, 1927, Manazuru village was elevated to town status. On September 30, 1956, neighboring Iwa village was merged into Manazuru. A proposal to merge Manazuru into neighboring Yugawara was overwhelmingly rejected by a citizen's referendum in 2005.

Manazuru has a mayor-council form of government with a directly elected mayor and a unicameral town council of 11 members. Manazuru, together with neighboring Yugawara, contributes one member to the Kanagawa Prefectural Assembly.
