Ōiso

Ōiso is located on the coastline of central Kanagawa Prefecture, facing Sagami Bay of the Pacific Ocean. The area is generally hilly, rising to Mount Koma (168 metres) in the northwest of the centre of town. The coastline of Ōiso is sandy and is regarded as the western end of the Shōnan area. Ōiso remains a popular beach resort and holiday spot for residents of Tokyo.

Per Japanese census data,[3] the population of Ōiso has grown steadily over the past century, with a slight drop from 2010 to 2020.

Ōiso is the ancient centre of Sagami Province. The exact location of the Nara period provincial government of Sagami Province is unknown, but tradition and the place name "Kōzu" place its probable location within the boundaries of present-day Ōiso.

As a minor coastal settlement, Ōiso was under the control of the later Hōjō clan of Odawara during the Sengoku period. In the Edo period, it was nominally part of Odawara Domain, and developed as Ōiso-juku, a post town on the Tōkaidō connecting Edo with Kyoto. After the Meiji Restoration and with the establishment of the district system in 1878, it came under the control of Yurugi District (淘綾郡, Yurugi-gun). Ōiso became a town on 1 April 1889 with the creation of the modern municipalities system. Blessed with a temperate climate, and with convenient access to Tokyo due to the Tōkaidō Main Line railway, it was favoured as a seaside health resort by politicians and literary figures during the Meiji period after a glowing report on its location was written by noted physician Matsumoto Jun. Prime Minister Itō Hirobumi, Yamagata Aritomo, Saionji Kinmochi and Ōkuma Shigenobu, Foreign Minister Mutsu Munemitsu, writer Shimazaki Toson and zaibatsu founder Yasuda Zenjirō had summer residences in Ōiso. This popularity continued into the postwar era, and Prime Minister Shigeru Yoshida also had a residence in Ōiso to which he retired after leaving politics. The former Itō, Yoshida and Shimazaki residences have been preserved as memorial museums.

Ōiso merged with neighbouring town Kōzu on 1 December 1954.

Ōiso has a mayor-council form of government with a directly elected mayor and a unicameral town council of 14 members. Ōiso, together with neighboring Ninomiya, contributes one member to the Kanagawa Prefectural Assembly. In terms of national politics, the town is part of Kanagawa 15th district of the lower house of the Diet of Japan.

The local economy of Ōiso is based primarily on seasonal tourism, agriculture and commercial fishing. The town is also a bedroom community for both Tokyo/Yokohama and Odawara

Ōiso has one public elementary schools and one public middle schools operated by the town government. The town has one public high school operated by the Kanagawa Prefectural Board of Education. There is also one private elementary school, middle school and high school. The private Seisa University has a campus at Ōiso.
