## Demographics

As of 1 May 2019, with the city's estimated population of 36,865 and per Japanese census data, the population of Atami has been in slow decline over the past half century.

## History

Atami has been known as a resort town centered on its hot springs since the 8th century AD. In the Kamakura period, Minamoto no Yoritomo and Hōjō Masako were notable visitors. During the Edo period, all of Izu Province was tenryō territory under direct control of the Tokugawa shogunate. During the cadastral reform of the early Meiji period in 1889, Atami village was organized within Kamo District, Shizuoka. It was elevated to town status on June 11, 1894, and was transferred to the administrative control of Tagata District in 1896.
The epicenter of the Great Kantō earthquake in 1923 was deep beneath Izu Ōshima Island in Sagami Bay, close to Atami, which suffered considerable damage, as did other municipalities throughout the surrounding Kantō region. The tsunami wave height reached 11 meters (35 feet) at Atami, swamping the town and drowning three hundred people.
In 1932, Japanese authorities raided a meeting of members of the Japanese Communist Party in Atami.
The Inagawa-kai, third largest of Japan's yakuza groups, was founded in Atami in 1949 as the Inagawa-gumi (稲川組) by Kakuji Inagawa.
In 1963 the Japanese Communist Party established a study facility in the mountains near Atami. The JCP holds a triennial congress there.
The modern city of Atami was founded on April 10, 1937, through the merger of Atami Town with neighboring Taga Village. After the proclamation of Atami as an "International Tourism and Culture City" by the Japanese government in 1950, the area experienced rapid growth in large resort hotel development. This growth increased after Atami station became a stop on the Tōkaidō Shinkansen high-speed train line in 1964. In concert with its famous onsen, Atami was known for its onsen geisha.
Atami experienced a considerable decline in popularity as a vacation destination due to the Japanese economic crisis in the 1990s and the associated fall in large group company-sponsored vacations, but is currently experiencing a revival as a commuter town due to its proximity to Tokyo and Yokohama.

Following torrential rainfall a landslide was triggered which swept through part of the city on 3 July 2021. 27 people were killed and 3 were injured.

## Government

Atami has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 15 members.

## Economy

The economy of Atami is heavily dependent on the tourist industry, mostly centered on its hot spring resorts. Commercial fishing is a major secondary industry.
