Susono (裾野市, Susono-shi) is a city located in eastern Shizuoka Prefecture, Japan.

[3] During the Edo period, the area was mostly tenryō territory under direct control of the Tokugawa shogunate.

After the Meiji Restoration, on February 1, 1889, a train station was opened in the center of rural Suntō District on what later became the Tōkaidō Main Line connecting Tokyo with Shizuoka.

Susono has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 19 members.

In April, 2007, the head office of Yazaki Corporation, an automotive components manufacturer, was moved from Yokohama to Susono.
