History
During the Edo period, all of eastern Sagami Province was tenryō territory under direct control of the Tokugawa shogunate, and administered by various hatamoto. With the establishment of the modern municipalities system the early Meiji period in April 1889, the area was reorganized into Hayama village through the merger of six hamlets. Hayama was elevated to town status in 1925.
Government
Hayama has a mayor-council form of government with a directly elected mayor and a unicameral town council of 14 members. Hayama, together with neighboring Zushi, contributes one member to the Kanagawa Prefectural Assembly. In terms of national politics, the town is part of Kanagawa 4th district of the lower house of the Diet of Japan.
Economy
Despite its lack of rail connections, Hayama is now primarily a commuter town for Tokyo and Yokohama and, due to its mild climate, a popular resort area with a marina. From the Meiji period it became a prestigious summer home location for the upper classes of Tokyo, partly due to the prestige of the Imperial villa. In the postwar period, its popularity continued with actors, artists and wealthy expatriates. Local agricultural produce includes shiitake mushrooms, and a brand of beef known as "Hayama-gyu".
Education
Hayama has four public elementary schools and two public middle schools operated by the town government. In addition, the Graduate University for Advanced Studies's main administrative campus is hosted here.
