A large part of the area was the tenryō territory in Sagami Province controlled directly by the Tokugawa Shogunate through the Edo period, though other parts were administered by small clans including the Ōoka clan, which is renowned for its descendant Ōoka Tadasuke.

In terms of national politics, the city is part of Kanagawa 15th district of the lower house of the Diet of Japan.
